What is DPF?
What is DEF?
What is EGR, and what is SCR? They are EPA Emissions Controls added to your diesel performance truck by Ford, Dodge, and Chevy. These have an effect on your MPG and power as well as the life of your engine. 1World Filter and EXTREME engine protection systems by InsaneDiesel.com want to arm you with knowledge and more. Here we show you what all these acronyms are and how to protect against the side affects of these catalysts and devices, and even improve MPG, Performance, and radically reduce engine wear whether you have a DPF delete, SCR, & EGR delete or not. Soot and other abrasives in your oil can only be removed by a bypass filter. 1World/EXTREME™ bypass oil filter is the absolute best way to keep oil clean, with the only patented progressive filtering that doesn't plug easily like other fine bypass filters. Fuel and its destructive effect in oil can be minimized as well through the use of NASA-certified EXTREME WS2 oil Additive. Love your truck? Learn more:

Please forgive chemical formulas that are not perfectly balanced, and mispronunciations like "Nitrous Oxides" instead of "Nitric Oxides" and Nitrogen represented as N instead of N2, etc.
DPF and SCR and CATs come in different orders on different engines and different years and with different manufacturers. The video information is just to present general basics of emissions controls and their effects on the engine and not meant to be a technical seminar with every variation explored and explained to put you to sleep at night. It's to give you enough knowledge to inspire and motivate you to protect that huge investment that is your diesel truck. Love it? Keep it clean! You're welcome.

As a diesel tech....I love all these additions required by the EPA.....Provides job security as shit keeps fucking up
That's government for ya
Talking outta your ass? Try getting educated on this process. There are some good videos on the process, if you can sit thru the entire 8 minutes and understand the chemistry. Here is it. th-cam.com/video/NPM40ey1OHQ/w-d-xo.html
@@brucelston sorry that was a bit harsh. It’s really meant for anyone who thinks they know better than the engineers and scientists who developed this and then did a delete of the def system. Providing more pollution that needed.
Lmao
What you describe is collusion that leads to oligarchy. You seem to be happy with that.
This guy knows how to teach and make it clear to newbies like myself. Thanks for being vivid and to the point. 2 thumbs up.
Thank you for your response. We will be posting more videos in the near future.
He chats shite ....
I did the deletes on my diesel pickup, and I went from getting 13 mpg to 22mpg. Getting better fuel economy = less pollution. The EPA crap is a contradiction. Burning more fuel to go the same amount of distance is not better for the environment nor for my pocket book. The only thing that the EPA crap does is force diesel owners to buy more fuel and makes the oil companies richer.
Couldn't have said it better! Thanks.
and clog up and wear out their motors so they have to buy a new car sooner
But if you deleted the DEF then you are now producing more NOX , you are burning nitrogen. I do not know how big a problem that is for the atmosphere, acid rain or what. I am inclined to distrust the EPA assessment of NOX but Im going to keep my DEF system because it is working and it is cheap.
if you do the delete on your pov i do not know the consequence of fines etc. as a professional mechanic i am NOT allowed to delete your egr system. the fines are in the thousands per day that they (epa) says it ran. ask Volkswagen how that worked out. they would LOVE to make an example of you and your pocket book. they mandate, we comply. if you don't like it, vote in someone who will make a change! like, i don't know maybe> MAGA!
Jarheads4Yeshua , i have a 2016 cummins megacab , im getting 22 hwy at 60mph. Any faster and it devours fuel. I have no mods.
Soooo we invented a way to make engines break down more... got it
Well the human race likes to destroy things if it's not one another, it would be good old mechanical engineering that was sooo simple and easy in them days now we like to build things that brake just by flicking it

Yup it’s either that or COPD and other diseases. But since the symptoms aren’t directly evident some would prefer to ignore them.
The EPA don't care as long as the animals in the north pole have a place to live without global warming the EPA would rather have us back to horse and buggy days
Lol

moiziz youre forgetting elbow grease, left handed hammers, steam in a can, universal allen wrenches, and paper stretchers.
dont forget skyhooks and brick stretchers!
Rookies yall always forget about arc start,spark samples, and tire air replacement
as good as it looks on paper, it doesn't matter what you do to control the emissions produced by the motor, those filters still choke up the engine and will never allow it to run at its best especially with a turbo equipped motor, i've seen many turbos fail on diesels simply because the filters and converters choke them out tremendously
As far as I understand, the EGR as what really contributes to that through depositing so much gunk into the oil. The engine can handle dirty oil for quite some time but turbos are far more sensitive to that.
Thank you for your reply.
Just adds to the thoery, that “if “ you want to keep your engine/carlong term, changed your oil & filter at regular intervals. Not at manufacturers (ie 5-10k not 20-30klms!!!!
where is the WPS? (wallet protection system)
You simplified all the terminologies in one single image and a video of 13 min and its crystal clear. Thank you very much
So in practice the only reason that these systems exist is so the environment wankers can feel satisfied
Tor Arne Bråten that and those b.s. acronym agencies / gov. can make money
Tor Arne Bråten yes and they can mak3 more money
Its actually from the clean air and water act of 1972, put into place by President Nixon as he was trying to out do a rival politician to garner public support. At the time, the environment was a large political platform. Nixon also created the EPA, but soon found it to be a hindrance to him and tried to cut its funding and render it useless, however he had allowed safeguards to be put into place to prevent that from happening, as an environmental legislative entrepreneur wrote the bill, and not Nixon's staff (because they were to lazy to write the bill themselves). Nixon, trying to show off actually made the bill more strict than the "Environmentalists" did, to try and outdo Senator Edward Muskie, who at the time, was considered the largest supporter of environmental policy; and was polling better than Nixon. So it wasn't to please those "environment wankers", it was shady politicians trying to garner public support for re-election. As the majority of the United States was suffocating from unregulated surfer dioxide and nitrous oxide emissions from manufacturers who were over polluting and causing major health issues in large cities in the late 60's and early 70. So really if you think about it the bill came into effect because of those conservative industrial greedy wankers. You should also look up the "Tragedy of the commons", might learn something. Education is something people on TH-cam should invest in!
Oh and you can also blame those "Canadian wankers", as they put tremendous pressure on the U.S. to tighten regulations on pollutants (in the early 1980's, I believe it was 1983 when they increased the legislation on the clean air and water act (amending it)) because the air pollutants were all going north and causing large amounts of acid rain, which was impacting soil pH levels and starting to have large degradation on forest growth, and as a domino effect was impacting the animal and other plant ecology.
Preston Gladd fuck Nixon
$8000 for new part or... 1500 for straight pipe and voided warranty, its about to get a lot louder in here bud
Am not sure with a straight pipe youll pass inspection when time comes.
I’m only a first year student in my school’s diesel program but wouldn’t it be a lot more than $1500 to delete all that stuff? I imagine it would be even more than $8000 if you could even find a shop that would do it
@@geoffrey9888 where I live we don’t have inspections
@@bradsmith2661 it’s not that hard to do it yourself if you’ve got the tools
@@jakefournie5930 You must be lucky then. Where i live there are inspections every year and failing inspections means the car is unroad worthy. Its crazy in our country.
From a mechanics view, I've had so many problems with EGRs... they're always such a pain
Frequent cleaning should help.
Thank you for showing me what all needs to be removed
I bought my 2015 dmax brand new. I deleted it about 3000 miles in. Best thing I could have ever done. It took one limp mode on the interstate to make up my mind.
Drill a few big holes thru the DPF, block of the EGR and be a happy camper
I’ve never actually sat down and done my homework on the light diesel emissions equipment. This was a pretty good break down. Clear and concise, I dig it.
best explination I have ever heard on this subject!
One word... AWESOME! As a potential diesel owner, this was VERY informative. Thanks.
Awesome ?🤣🤣🤣
Don’t buy a diesel.
Buy a pre-emissions diesel.
Awesome?? What you gonna do, buy a petrol??
@@richardjones3112 Diesel engines will always have more power and sound better than gas engines. I bet you drive a Prius lmfao
Ah yes DEF..... Saving our planet one plastic jug and cardboard box at a time.
Ya know that's funny Because a Mechanic in My shop who is very good at what he does even suggest for us to get a drum and containers instead of us just going thru those 2,5s and what not... BUT NOOOO the CHEAP Company which is very BIG for UTILTYs in this country disagreed yet we go thru training on saving the environment. Pretty Much the definition of OXYMORON. With this subject around here..
Some truck stops in remote areas have dumpster full of plastic jugs
where the hell do you live? I've never seen DEF at a pump. Not saying that they don't exist....but I've seriously never seen it available from a gas station pump.
sold inside stores
Wesley Richardson Regular car gas stations, that also carry diesel will not have a def pump, but almost every big truck stop in the country has a def pump next to a diesel pump. Major corporate truck stops like Pilot, Flying J, Petro, TA, Love's are guaranteed to have it at every fuel isle.
Excellent presentation 👍 I got VW T5.1 BUS 🚐 4Motion 2.0tdi 140.HP. And after I watch this video, I will immediately order my VW Bus to my mechanic to EGR and DPF Delete. I have no problem with that system but, but that garbage which will destroy my engine. Diesel power 💪. Greetings from Croatia 🇭🇷
Every single diesel vehicle owner in the world should watch this video right now!
Absolutely the best video I've ever seen on YooToob. Thank you, sir.
TH-cam''
You have a gift of teaching as well, If you buy a diesel car make sure you know everything about it. Have to do the right thing. Thanks for your knowledge and thanks for sharing.
Thank you. Knowledge is power :-)
I did egr delete with a turbo back 5” straight pipe on my ecodiesel 🤘
Simple and concise.
I was trying to remember why we were dumping fuel and dpf in exhaust system.
Diesels are very common in UK, esp the Chelsea Tractors (Urban SUVs) going on shopping trips and taking kids to school on short journeys.. People simply do not understsnd, that they need to go on long journeys.. Personally, i have had nothing but problems with my city Diesel. I personally had to learn how to use it and clean the EGR valve and DPF.. but have learnt so much about general servicing.. thank you, your video is very clear snd informative
Thank you. My brother explained this to me, but since we are brothers I thought he was full of crap but apparently knew his stuff lol.
😆
This was explained very well, and being a newbie to diesel trucks (and will never go back) helped me to the conclusion that I do want a egr delete and downpipe. Thanks for your info.
Excellent choice
New to the Diesel world (2017 F350 6.7L) I have watched 100+ videos, read forums, and talked with a few longtime owners. This was the best video to teach me about the engine process and understand the EPA junk. I literally emailed Banks Power Corporate with a, "If I have to be EPA compliant, how do I correct the EGR, DPF, and SCR problems with aftermarket solutions?" They got back to me by suggesting their tuning module, pedal controller, intake, and exhaust.... So the boastful "EPA Compliant" company doesn't have a solution for any of these systems. My Vote - Delete everything. I would think the Aftermarket community would have "Compliant" fixes with upgraded systems. Hell, there's probably Government grant money for companies to do so. But there isn't.
I've got an older 2000 diesel truck. Getting about 23mpg. I blanked the EGR valve and ran a straight thru exhaust pipe. Getting about 30mpg now. And its the best its ever run.
Good!
what brand ///engine
30 mpg on a medium size diesel truck? Dude, what truck and what engine?
Thanks! Great explanation! You've helped me understand how my bad DPM filter can cause dirty oil and damager to my engine.
You are welcome.
Best explanation I have heard on DEF thanks
Glad you liked it :-) Knowledge is power.
This is the best explanation of the processes I've seen or heard anywhere. Thanks
Thank you. Knowledge is power.
If the manufacturers would finally listen to people and come out with an EGR that shuts off when regen mode engages the world would be a happier place.
thank you so much , I've been searching for this information and you just put in a nice convenient way ,great explanation .
You are welcome. Glad to help.
Excellent video for giving folks an understanding of the word salad of the initials of fail in a modern diesel emissions system!
Glad we could clarify your word salad.
This is the most informative diesel video I've ever seen. THANK YOU SIR!
You are welcome.
I have a 2000 detroit diesel series 60 with 1000000 miles plus and that thing runs cleaner than any new engine which would spend most of its 400000 miles in the shop.
Thank you for the video.
Great video, a very simple way to have a better understanding on how the system works or better said Supposed to work.
Thanks again
Basic but valuable info for the diesel owner. Thanks for your feedback.
I have a 2014 jeep grand cherokee eco diesel. Had a recent recall on this EGR since my jeep was over heating. Since its been great 👍
the egr delete kits works wonders, also..using tap water instead of def fluid works too...in commercial trucks-it is all about operating costs and def/egr expenses do indeed factor in
Terrific and very informative video. Thx for the hard work.
This is the dumbest design..I've had my semi in the shop constantly..From failed nox censors..act problems..I'm turning 2 Delete..
Thanks a ton!! Was very informative!!
My truck is a 2006 with a 6.0 turbo-charged diesel. It doesn’t have an EGR valve and based on this info, I’m thankful.
Thanks for this video this is something every owner op should watch
This just confirmed that im doin right in keepin my 300k mile 05 ram
They will write books in the future about how stupid this system was for engines and how bad of a design it was.
They set the Diesel engine back 10 years with this disaster.
Gcal1956 10 years back means great Diesel engines lol. I got what you mean though, it’s weird this time around. Older is better as you know.
Yip..Look at 6.0's
Gas trucks will now outlive trucks with all this stupid def/dpf/epa bs
Except that now a 2.8 Duramax produces almost the same power as the original 7.3 ford diesel did. But whatever.... can't argue facts and logic with an idiot
ohgodwhat1 good luck towing anything bigger than a lawnmower with the 2.8 Duramax.
I solved all the issues with my exhaust scrubbing systems. I took that crap off. My fuel mileage went way up and now my exhaust looks really cool when I romp on the throttle.
One of the best explanations I have seen of this system and the reasoning.
Thank you!
Actually, this clown does know what he’s trying to explain. EGR cools combustion temperatures. That’s how it avoids creation of NOx.
Great video and thanks for the education. Just kinda skeptical about the infomercial at the end.
And to those who believe the government is to blame and they think they know better? Go ahead and try to invent a better way that pollutes less and costs less. No a deletion of the whole system is not an option. That creates more pollution. But many mouth breathers who don’t care about climate change and the air quality think a delete is ok. It’s the best we have so far. Let’s hope they get better systems in the future. Again thanks for the education.
I burn a lot of diesel in my tree service and I do sometimes think about the amount of pollution that I'm putting out. But my trucks are all pre emissions and I can actually afford to work on them
@@edwardrook8146 , I totally understand, my comment was really to those who remove the items required by law/epa. Thanks for sharing
Basically, the truck runs better without that junk on the engine!
you can't take it off without redoing the whole computer shit... truck won't start without it
And a big fine if you get caught
My buddy just put his 2011 Pete in the shop for $21,000(warranty) & the truck still isn't right.....FUCK THAT WARRANTY! It doesn't cover your downtime.
B______ F________ is that all i would need to do? im buying a 2012 srt longbed 2500. i want them to do all the work for me at the shop while its there. i appreciate all your knowledge man. this is my first diesel truck. im rigging it out for welding
And most the fuckin time they cant mechanic their way through a simple fluids change... atleast the local dealer here cant. local dude had his pickup at the dealer for over 6 months because they couldnt get it to start(one of their guys some how fried the computer) so they put a new one in... turns out they put an auto trans computer in a stick truck, damn thing was looking for park and wouldnt start without that...
I really learn a lot from your short lesson. Thank so much for making it so simple to understand.
You are welcome. Glad to help.
Holy Moses, this is a great explanation. Very methodical and easy to follow at a great pace. I also like the stopping and check on learning.
Thank you.
outstanding information!
Very interesting video and well explained. Thanks.
Thank you.
Holy cow! I'm so glad I didn't buy new like I was going to. I found a sweet 2002 Silverado HD w 40k miles. Looks like I'll be keeping it for many years to come!
The EPA and the Federal Government KNEW long before these regulations came into effect the damage EGR and DEF would do to diesel engines. Yet they passed them anyway. This was Clinton Era EPA that came up with the regulations. This is why CAT no longer makes on road use diesel engines. CAT, Cummins, and Detroit Diesel testified before Congress on the damage these new EPA regs were going to do to engines and the negative impact on the trucking industry. No one cared.
My last truck, a 09 Western Star, had probably the BEST emissions setup. NO EGR. It had a 60 Series Detroit with a Re-Gen system. The exhaust system had a DPF, and the entire exhaust system had fuel lines and spark plugs at intervals along it. There were sensors for soot every so far. If ANY sensor showed soot, from that sensor back got fuel shot to it and ignited by the spark plug. NEVER in 450,000 miles I drove that truck did I have ANY soot issues or problems. The engine was California Certified Clean Diesel.
That sounds like a much better system @mean45acp, why don't they make all cars and trucks with that system? I.e. what's the downside for them? (Apart from us not having to have them serviced as regularly, replace them as often or buy fuel as frequently, obviously!).
So it the EGR system that hurts the system. I could leave the DPF and DEF/SCR system in play?
Trade off from soot to the DPF then produces nano particles which pass through lung lining to the blood stream! Great stuff!
I know you wrote this forever ago but could you please elaborate? What are you saying?
Best explanation on this subject I’ve ever seen!! Thanks
Looks like the videos a couple years old but the info is still very good and relevant and the outro music is kick ass!
DEF isn't ammonia, it's urea CO(NH2)2. Congratulations for your lectures, thanks a lot.
So, i brought our F-550 from 11mgp to 24mpg with a emissions delete, my question is how does burning more then twice the fuel more eco-friendly? burning it clean yes, but twice as much.... come on
Kyle Ranger r
it dosent. it just makes it looks like it sows
"Does"
That's the way our government works.
you probably had a clogged dpf trying to regenerate continuous
I found a woman near Clear Lake California with a old dually F-350 and UNDER 250,000 miles and a Excellent fifth wheel hitch already installed. Asked her what she wanted for it. $13,000 she said. I stayed calm and bought it 5 years ago. New front brakes, a turbo tube, 7 Tires, 8 injectors with valve cover wiring to improve cold start and a shudder..a side mirror and some paint. I'm in Love.(Injector job was $3,600 - OEM - by a Diesel shop).
Great informative video on how a modern diesel engine works and the benefit of an adblue system.
Also any video that ends with led Zeppelin gets a thumbs up from me.
This has been super informative, thank you for putting this together! Some clarifying questions:
So with deleting, can I deleted everything but the DEF/SCR and then run it while still achieving mileage and power/efficiency gains, without causing backpressure back into the engine? or does the SCR still cause some backpressure?
Based on this video and the comments here, I would keep SCR but without a doubt delete EGR and DPF.
We appreciate your kind words.
My DPF has already been removed... Removing my EGR soon!
The thousand dollar question is: What are the consequences for the engine and computer settings? I guess you are not even filling DEF? What about that gauge?
Best explanation I have seen yet for diesel emissions junk
Very good explanation of the DEF system and Diesel system
Great video. Thanks a lot...
nothing like the smell of def when its scrubbing.. smells like some sort of acidic pepper spray combination.. But those are good emissions lol Id much rather smell diesel fumes..
Mike Baer you could say it smells like burning piss, probably because it is
Those chemicals really worry me, I've noticed them a lot lately and they make me feel really bad when walking past a vehicle that is spewing them out (bad as in I can't breathe) I never had that problem with regular diesel exhaust.
He'll yeah
@@littlemisssunshine2931 same here but the epa says its healthy
I love the smell of diesel early in the morning.

Great video, very informative. Just an FYI though, NO2 is technically "Nitrogen Dioxide." The "Nitrous Oxide" you are referring to would be N2O, which is also known as "laughing gas"
Thank you for letting us know. We will make the correction.
Fully Deleted. Full Bolt Ons. Tune.
Enjoy more power, better fuel economy, better throttle response, and, if your tuner is competent, no smoke or other problems.
I just bought a 2009 Ford Mondeo. You guys in the US probably have never heard of the mondeo but they are popular here in Ireland. It has the 1.8 litre tdci engine. Great engine that Ford have been using here for years. It has no dpf but it does have an egr which I will be blanking very soon
One of the best videos on TH-cam. Well explained by keeping it as simple as possible so that someone like me, who has no knowledge of how an ICE works, can understand it.
So let me get this straight..... Adding an EGR gives you less emissions, but worse fuel mileage and more wear on your engine. Adding a DPF gives you less emissions, but worse fuel mileage and more wear on your engine. Adding a SCR and DEF tank will give you less emissions but potentially worse reliability. So is all this emissions out of the tailpipe being reduced worth it if you may have to rebuild an engine in 400,000 miles? Is that really more green vs. a truck pre-egr that can easily get 1-1.5 million miles before a rebuild?
It's about destroying your car under ecological pretext. It's the genocide agenda , making your life difficult every way they can.
If you think about it, 400k is a decent run for even reliable diesel engines. Most have failed before that point because of bad maintenance habits. Vs a single owner truck well maintained that you can expect 1M miles because he spent the time and money to keep it healthy when nothing was wrong with it yet. I think these factors still matter more
@@danielandries3240 It's communist. Thats what the communist party did to the Russian people.
@@edwardrook8146 my truck 🛻 after only 55K miles is at the shop, for what you asked? That’s a great question, the EGR was clogged and damage a few other components
I must also add that I bring my truck for regular maintenance, last oil fuel filters change was around 5K miles ago
@@Pinpon-ni8vc My sympathies to your truck situation sir, I certainly understand the EPA mandated technologies are very unreliable and can be destructive to even new diesel engines. I have all pre-emissions diesel trucks in my fleet so that is what my experience is limited to.
Best solution: bring your diesel to a tuner and let them remove the EGR from the software. Then the dpf wont have to run and your gas mileage goes up. In Holland the yearly MOT doesnt check the software en the NOx stays within the limits because the MOT limits on used cars is lower then the limits on newly developed cars. You could even try and remove your dpf but that could be noticed by the MOT
Best answer yet!
Then it plugs up, right?
Sorry but you're wrong. The DPF will still catch soot, it's how the engine works. I had my EGR disabled and yes the DPF would no longer regen but the Differential pressure sensor through a code because the DPF was getting clogged. Just do it the right way and remove everything and have it all disabled via software.
@@1tokeover Is it still possible to do a delete since the EPA is more strictly enforcing their draconian rules ?
Thank you for this information. Objective and factual. Excuse me while I remove every piece of equipment you just covered.
Very good video. My Mercedes Benz E320 Diesel is having a issue with the DPF and the low efficiency of the engine is very noticeable.
Hi...Im not here to have a go at you...Your diagram is excellent but its just that my 1kd had severe sooting problem in throttle body, Inlet Mainfold and Inlet port in head which was created by PCV (Oil vapours) and EGR.
Joe mine also has severe soot. Sent to dealer and they said repair or replacement is thousands. Instead I sold em the truck bought new and now looking for delete options.
A very informative video. With the EGR reducing the Nx by cooling the exhaust gas which is in opposition to the DPF which needs heat to remove the soot, the whole system is a mess. The result might be a cleaner tailpipe emission but an engine block chocked up with abrasive carbon and unburned fuel sounds like a recipe for expensive repairs. It is a pity as diesels have great torque and good fuel economy. Unfortunately I do a lot of short stop start driving so it looks like I am out???
Good luck.
Wow great video. Liked the video and subscribed. My 2017 John Deere 2032R has a dpf, probably other things too
Great video btw. It explains a lot in layman's terms!
Exceptional video! Great explanation of the process.

You're welcome. Knowledge is power.
They are all ways of decreasing enjine efficiency, so you use more fuel to be "cleaner"
The conspiracy theory about that exact topic is that oil companies are lobbying the government for exactly that reason. They ask the government to increase restrictions on emissions to make vehicles consume more fuel for 'clean' air.
@@MyWatchIsEnded it's not a conspiracy when it's clearly the case.
An inefficient engine that has to burn more fuel to do the same job means more immissions.
Having a free flowing intake/ exhaust with an accurate tune will save fuel and gain power. Less need to accelerate harder to do the same job.
@@marcusbarnes5929 agreed plus their definition of "efficient" is severely lacking.
They cry out how semi trucks are "inefficient and polluting" and yet they never account for the fact that semi trucks are doing necessary 'work' and that they're making 4-10mpg from 34,000lbs to 80,000+ which is by definition efficient since they are making acceptable fuel numbers for a lot of work produced.
Is it efficient for a car carrying one person 300 miles and burning 24 gallons or is it efficient that an 80,000lb semi is carrying 45,000lbs of cargo/goods and only burning 50 gallons in 300 miles?
that's why we delete all that bullshit!
Chad Irwin : hey bro do u know they delete that Bullshit
Really great explanations mate. Cheers.
Good instructional video 👍🏻
the world's gone mad, we're designing engines to burn more fuel to be better for the plannet! not only that all the fuel and energy to produce new parts just for the cleaning process, more expensive services extra running costs which means we have to work longer hours using more energy !!.
That's slick way of getting that $$$$ , use global warming polar bear starving tactics to end up making more $$$ , less fuel efficient diesel having to consume more fuel , paying for def, higher price tag from the manufacturer , keeping the dealership busy , by you having aflawed system keeping you in the shop
New Diesels suck.....back to gas or even electric
Yes in Texas I once owned a honda CRX with an econo vtec engine getting 50 mpg and it wouldn't pass ppm emission tests. But a ford excursion getting 10 mpg did just fine.
IS it possible to buy Diseal engine with out the EGR system?
Scrappy ChildHood - Glider, new body old engine, but it has to be the only engine ever in the vehicle, it is against the law to replace an engine with an older engine.
The dpf collects soot and ash. The truck series today has been creating over heat which then cracks the egr cooler that sends coolant to the dpf and burns.
Your def fluid is injected into the scr. You have an injector for the def and dpf for fuel.
We do oil sampling to check our oil from being contaminated. Nox sensors you have 1 on the intake and the 2nd one on the exit. The def fluid is injected in front of the scr. Depending on the truck i have seen Macks heat at the dpf around 1200 degrees. There is also a SCR crystalline regen that creates a heat range near 1600 degrees. Every def tank i have seen has a tank heater. This is a heater that uses engine coolant to heat the tank.
If you want to keep your truck running take it to an Aftertreatment specialist.
The aftertreatment uses a differential pressure sensor this is located on or near the dpf it has 2 hoses that recieves pressure from both sides of dpf. The computer uses this sensor to activate the regen when the numbers climb. When you have your laptop on your truck you can see the soot levels and ash.
great video, very clear explanation!
We shouldn't be forced to use this system till its perfected
HGVs have been using it since 2006 in Europe.
40,000 miles mine failed pulling my camper and was forced to find a dealer. They couldn't fix it right away and had to set up camp at the dodge dealer. Now I got 57,000. Am I going to break down every 40,000. They said it couldn't regenerate fast enough.
now mines in the shop getting a whole new system.
just delete the thing. keep the shell of the DPF and keep the stock system kicking around for when you sell it or is checked for emissions shit the shell will make it look stock and passable
And it the UK, they plan to completely ban Diesel and Petrol cars in 2040. @@lynalllynall9082
Yeah let's run unburned fuel back into our intake... Less mpg, less power, less life. Screw the EPA
EPA did not invent DEF etc. EPA simply required a reduction of emission and this was the solution implemented by car manufacturers. More things to buy and maintain for the owner. A capitalist decision that benefits manufacturers.
@@gregoryreeves3686 Still EPA's fault
You are correct sir! =] The EGR system is ONLY used in the USA. The GOAL was to make a terribly inefficient engine concerning FUEL ECONOMY and doing that turned out to make horribly polluting engines.... SOOOOO they designed the EGR. It allowed the engine to continue to guzzle down fuel and a ridiculous rate AND reduce the emissions to an "acceptable" level. Truth be told... we have the technology AND have had it for decades.... to produce extremely efficient engines (fuel economy) with extremely low emissions... but we don't. Because they want your money. TAXES on fuel sold in the US account for over HALF of the total intake by our government. You think the government runs like shit now? What do you think would happen if they LOST all that money every year.... they probably couldn't operate at all. It's about MONEY... plain and simple.
@@liberty9348 mate the egr is used all over the world not just in USA.
I'm in the UK and have an bmw 330d and they all have egrs
They don't give a rats arse about repercussions of dpf on a Hwy diesel because they don't foot the repair or rebuild cost if they were bet regulations would change quick smart
This is a great video and very clearly states how mad the word is. I drive a 09 Nissan 2.5 Hardbody / Navara /np300 in Africa, with no real emission laws here. I had a straight through (2 muffler) exhaust installed for $200, fitted a EGR blank for $5, Had a chip installed for $300 (Dyno included) and had my boost notched up just a small little bit by playing with the waste gate (Not to much, i realize this is not always good). I still change my oil as often as i possibly can and my truck runs circles around the larger 3L model. I have gained 30% in power and 20% in fuel economy. The motor is far more responsive, and the exhaust runs clean (visibly). I have driven the truck for 7 years now and have never had a fault. I strongly suggest that you delete all these ridiculous items from your vehicle, and enjoy saving the planet with far more power :)
That is good to hear.
Gotta drive a truck everyday with egr and dpf. It's something everyday with the damn egr messing up. No power, no boost, fluctuating boost, check engine, no power getting hot, re-gen, no fuel mileage. Got damn.
Great video, I do have a question. If you have a DEF diesel does that take the place of the extra fuel that is put into the engine. (4:00 on video) for the DPF?
DEF doesn't replace the DPF, but it does often create a more efficient combustion because the DEF lets the engine run hotter, reducing soot that plugs the DPF. That means the DPF will go into re-gen mode less often. Better for gas-mileage because less re-gen means less wasteful fuel injection.

To answer your question correctly, The DEF system has a dedicated injector in the exhaust stream so its better for your motor than the DPF old school systems that run your motors injectors on the exhaust stroke, washing the oil off your cylinder walls. In 20 years this stuff is going to be looked at like a sick joke.
Is it possible to do a EGR/DPF delete and still keep the SCR? Would there be any benefit or should a person (in theory) just delete everything behind the turbo, except maybe for a muffler if needed?
Volatile to provide an even more correct answer, def has nothing to do with the combustion process. It simply injects urea into the exhaust. This urea pulls even more nox from the exhaust. In the newer emission equipped trucks there is a separate fuel injector, usually in the downpipe, the injects fuel directly in the exhaust completely eliminating the injection of fuel at an improper time
