While funny, there is a big difference. EGR has some benefits besides soley emissions. It increases intake air temperature, decreasing the air density, which allows the car to lean out the air/fuel mixture to a higher degree. The exhaust gas also contains unburnt fuel and oxygen, further increasing efficiency. On some cars, like my Honda Civic VX, this helps contribute to very high fuel efficiency. On performance cars, it sucks though for sure.
Now with big truck diesels not only do you eat your own shit,, the DEF system staples ur stomach for the purpose of CATCHING any crumbs of your shit you may have missed. And it holds them there in your stomach while heartburn tries to fart them out (regen) but at some point you can't fart, or even eat anymore of your own shit due to inability to digest at all (clogged filter beyond regen ability to clean) Then you have to have expensive surgery to open u up and take your stomach out to clean all the built up crumbs that can't be digested or farted out (crankcase oil soot will not regen and must burn out at service center with removal from truck first) keep in mind the egr concentrates the contaminants that clog the exhaust filter, causing engines to run hotter and fail closer to 700k rather than 900-1mil they used to get between overhaul, AND the egr cooler fails more often cooking your turbo that overheats as it tries to build enough air mix pressure in manifold to combust in cylnder as piston peaks trying to add final pressure to cause explosion - but lacking in density so more rpms are needed to get same power, causing hot engine to work that much more.
The EGR valve is fitted to cool combustion down to a level where oxygen and nitrogen will not combine together to form NOX in the first place in the cylinder. Nitrogen is normally inert until it gets too hot then it will react with oxygen to form NOX. EGR or Exhaust Gas Recirculation recycles some of the already burnt gases, (which will not burn again) to slow down and cool down the combustion hence reducing NOX. The catalytic converter takes care of the rest.
On my car the exhaust gasses used for recycling are not cooled so there is a performance impact in that the inlet charge is not as cool (dense) as it could be however I suspect the performance hit is tenths of a percent per degree. I wonder if I put a water jacket round the pipe it would help?
This EGR setup has shorten life and damage my engine which only done 168,000kms due to PVC (Oil Vapours) mixed with EGR valve which has clogged up atleast 30% Throttle body, Inlet Manifold and Head Inlet ports.
so deleting the egr system will cause more harm to the environment but it will also increase horsepower? egr in turn dilutes the air/gas ratio causing less power?
do u know why I keep getting a cade for egr vavle insufficient air flow does that mean its clogged I put a new one but I didn't clean anything ,I see videos for cleaning the holes in the manifold and things likle that any ideas ,2001 accord ,also replaced evap system and can sesors so on.
Could you please add audio to this animation. i have a training coming up on EGR system and i would like to use it to demonstrate the working of the system. i would really appreciate if you can upload the viseo with the audio, doesnt matter if its in german.
Two things here, in theory water injection would do the same thing but would need to have a system to do this. If it was better than EGR the car makers would use it. Yes, you could blank off the egr valve and have more power but you would of course then be harming the environment more that way, you may also cause problems with the cat having to do more work than it should.
Well, to understand better you have to ask VW opinon on EGR. Do not remove. Maybe install an orifice at 1/2 the diameter of egr outlet port?. Those who buy diesel engine but travelling distance less than 10km per direction or 10km per stop will have serious carbon problem?.
while its good in theory, i does more harm than good. i soots up the valves, intake manyfold, the flaps. its a nightmare to clean the plastic intake manifold from it.
@punchmaster123 EGR pretty much re-use's exhaust gase's + coolant. too cool it down. witch in any case is a Horrible idea.. Because for Diesel.. soot will clog the crap out of it And like any diesel black soot is unburnt fuel. witch with a right computer can fix the usage. ERG stands for Exhaust Gas Recirculation. bad idea..even though delete isnt legal. i do NOT care. better than spending 4k on rebuilding the motor.
Worst thing ever invented. Okay it decreases NOx... But almost every engine throws crankcase vapors back into the intake and mixes with exhaustgas. Result: clogged intake, less efficient engine, smoking,.. Even worse for environment (small soot particles). This will happen sooner if you drive like an old lady... A petrol engine equipped with MPI will have less problems because of cleaning effect of the fuel but on direct injection cars it is a nightmare.
You're confusing a PCV system with an EGR system. A PCV, Positive Crankscase Vetilation system actually contributes to the logetivity of an engine by helping to vent crankcase gases, and thereby reducing sludge buildup.
Cleaning is not hard, you're only cleaning the egr that the vacuum hose is connected to. Although there are cons, advantages are more relevant such as emissions and better mpg. And yes environment free emission is important, back them you wouldn't see the light with all the emissions in big cities, it was bad.

EGR is a piece of shit! I don't know why theres a need to put so many complicated systems in a car when 20 years ago cars were more simple, had very little electronics, were more reliable and easier to repair! I'm sure they polluted the enviorment less too. My Golf 3 Variant from 1996 will last longer than some 2010 cars... Car companies are scumbags these days.
engine with ERG is like human who forced to eat their own shit, for better food efficiency.
best answers ever .....

You , Sir , are a Master Mechanics Teacher ! 😊
ahahhah yep respect broo :P fuck egr bullshittt

How much NOX is produced? Any thought ideas?

Is it normal to have a little space between the egr tube and the intake manifold. I can't seem to fit them into each other perfectly
great video - can u post audio to go with it?
This EGR setup has shorten life and damage my engine which only done 168,000kms due to PVC (Oil Vapours) mixed with EGR valve which has clogged up atleast 30% Throttle body, Inlet Manifold and Head Inlet ports.
so deleting the egr system will cause more harm to the environment but it will also increase horsepower? egr in turn dilutes the air/gas ratio causing less power?
What would be the temperature difference in the combustion chamber with vs without recirculated exhaust gas?
Watching this right after I ripped mine out lol. I don't want the nasty shit clogging up my engine.
do u know why I keep getting a cade for egr vavle insufficient air flow does that mean its clogged I put a new one but I didn't clean anything ,I see videos for cleaning the holes in the manifold and things likle that any ideas ,2001 accord ,also replaced evap system and can sesors so on.
did you ever get a response for the audio?
When does the EGR valve work in this video??
Could you please add audio to this animation. i have a training coming up on EGR system and i would like to use it to demonstrate the working of the system. i would really appreciate if you can upload the viseo with the audio, doesnt matter if its in german.
If the egr inlet line has a crack will it make the engine rev. Really high and die?

Yes, you could blank off the egr valve and have more power but you would of course then be harming the environment more that way, you may also cause problems with the cat having to do more work than it should.
There once were som trucks adding water to the fuel. Only with very low temperatures it did not work

So that is the thing that is most likely making my engine cough... Hmm
so I am watching this presentation, and wonders how that could be bypassed...
erg delete kit and changing some parts of the software on the car
Saw the exhaust then and divert it away
EGR cooler? What could go wrong with that? They might as well call it the EGR clogger upper.:))
Do ineed a scanner before cleaning the egr?
for a second i thought my speakers weren't working.
about a six 4.9l 300 CID ford motor
I thought I was going def because I can't hear nothing
while its good in theory, i does more harm than good. i soots up the valves, intake manyfold, the flaps. its a nightmare to clean the plastic intake manifold from it.
on load egr close
some how im more confused
No sound....
Can you add that on some vehicles that EGR valves are a royal pain in the ass!

do you have a video that shows how to blank it off?
John has a point about the cat, Best remove the cat while were on blanking the EGR, Al gore will be turning in his grave
by german i mean greek
So for educational purpose you put a V engine ???

BLANK THE FUCKING THING
Or you could put VVT and not use EGR...

How to create this kind of animation, ,pls help
Gotta love my 24v cummins! None of that dumb shit to go wrong.
best thing to do is just bypass it !
and for the ford mondeo duratorq diesels: just put them in the shredder we don't want them on our roads anymore
you only getting %20 fresh air an %80 carbon exhaust, fuck epa
DIESEL ENGINE KILLER .................
egr, just another thing to go wrong, blank it off !!!
EGR is a piece of shit!
