In this video, we're going to learn how different exhaust emission system works.
A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction.
It is installed on every internal combustion engine car, be it diesel or gasoline. The harmful components released by automobiles are Carbon Monoxide (CO), Hydrocarbons (HC), Nitrogen Oxides, etc., from their exhaust pipes.
As we already know, the exhaust gases from cars contain pollutants that aren’t healthy for the environment, and hence, the Catalytic Converter commonly known as cat-con began to be introduced. The Catalytic Converter is placed or fixed in the exhaust system of the vehicles which is convenient to perform the operation.
The catalytic converter consists of a special catalyst. It is made of platinum and palladium which carries out the chemical reactions. Pollutants like carbon monoxide convert them chemically to less dangerous pollutants like carbon dioxide. The harmful compounds mainly include nitrogen gas, carbon monoxide, hydrocarbons, nitrogen oxides, etc.
Where is a catalytic converter located in a car?
Catalytic converters are placed as close as possible to the engine because they require a temperature of 400 degrees Celsius (752 degrees Fahrenheit) to operate effectively. They are usually located underneath the car in the exhaust between the engine and muffler. The catalytic converter is wider than an exhaust pipe and looks like a muffler.

Just finished an LS swap and had no problem adding a "High Flow CAT", operates as originally designed for the donor vehicle. Still get amazing performance, win / win. Good video, learned a lot, and you stuck to engineering NOT propaganda, thanks.
Very informative and educational. We need more of this kind of information.
We all should care for the environment not just governments, Exellent work, Thank u,
Awesome video as usual and expert explaination...❤ Love from India.❤
Great information
Thank you
Well done, very informative.
so informative
I like your channel very much, so high tech.
To better help with understanding how the Regen works on diesel engines, if the ecu detects the dpf filter getting clogged, it triggers a injector that’s placed in the exhaust after the turbo to inject raw diesel fuel into the exhaust. The raw fuel reacts with the DOC and exhaust temperatures go up pass 1200degrees to burn off soot in the filter and turn it into ash which settles at the bottom of the filter and must be cleaned at prescribed intervals.
Also if the truck is driving and the exhaust temperatures are already hot enough it will actively burn off the soot in the DPF which is called active regen.
Or some cars (most cars?) use the existing injectors + glowplugs (rather than having an extra one) to inject extra post-combustion fuel and heat. Explained here: th-cam.com/video/Q4aI0-xIQsc/w-d-xo.html
@@xxwookey yessir the 6.4 power stroke is a example of that
Nice video thanks 🎉
Good
I learn so much from this video
Indeed thehnology is awesome you need to know when to put stop
Perfect explanation is cannot give 10$ now but I will say cheers 🥂 here.
I don’t remember PCV systems before 1968. The cars we had before 1968 were, 1960 Corvair, 1961 Impala, 1964 Impala and 1966 Chevelle. None of these had PCV valves. We had a 1968 Camaro and 1968 Impala and I think these had PCV valves. I remember that the California reguilations started in 1967 with the PCV valves and then in 1968 for the rest of the states. This was the time I started driving cars. My first unleaded car was a 1971 Vega, it ran so poorly on unleaded gas, that after paying $0.41 per gallon, I switched to regular leaded fuel at $0.25 per gallon and the car ran beautifully. My last new car than ran on leaded fuel was a 1974 Nova (straight 6 cylinder) and it ran perfect.
PS: cars seemed to get better as the years ran by. When I started driving Japanese cars, mainly Hondas, in the mid 90’s, I worked less on them and drove them more.
Back in the days, all those fumes and oil vapors in the crankcase were vented into the atmosphere. That's obviously very bad
It's very helpful... it shows that the catalytic system does not work. ....And there is a need for more engineering to make the system work and maintenance to clean hence 'filter'.
How long does the DEF last roughly or does it have to be replaced after a period of time?
Gets replaced once in 3 fuel stops
Why don't they add the urea stuff to the fuel in the filling station? Seems like that would make more sense. Unless there is some detail I don't know about.
The dosing rate is variable and independent of the fuel-use rate.
Urea is very corrosive, too, and I don't think it dissolves well into fuel. Also, it sounds like the diesel filters use the water the DEF urea is dissolved in to be part of the catalysis/consumption process, so dissolving urea in distilled water is likely better as a combination because people would need to add ONLY water regularly, which they almost surely wouldn't do. Plus we often just use tap water, and I wonder what effect 'a bit of iron in your tap water' would have on the DEF equipment...I bet it would make a mess of things. Hard water, soft water, all a bad idea so we'd have to use pure distilled water...but 95% of people would slap tap water into the tank and call it good enough, then they'd just b***h that they have to replace their catalytic converter/DPF/whatever "every twenty thousand miles and that's the technology's fault, not theirs for using tap water!" So, DEF using distilled water as its carrier is likely the best combination of things to minimize annoyance, rust, or engine failures overall.
They seem counterproductive
A catalyst converts without changing itself.
Oxidation catalyst is pladium and platinum
The first converters pumped oxygen air into the converter.
Mines was jerking and I replaced and the down stream 02 censor
With the amount of engineering, innovation and science put into modern exhaust systems,
I'm beginning to think that, "upgrading" my cars exhaust to be faster and LOUDER,
Might be the most ignorant and straight up disrespectful change I could possibly make to the car.
Lol.
Still might do it though..
For I am, a jerk.
:)
Reduction catalyst is rodium and platinum
Hi
The early ones get clogged rather easily we'd buy cars that wouldn't run hammer a long screw driver thru it and start right up....😅
What about 5 gas analyze how is work can make one video
Instead of wasting money on electric cars why not develop better exhaust filters for more emission reduction?
And to reduce old diesel cars!
Because Carbon dioxide is still a global warming emission.
Because the problem is now climate change which is driven by CO2 which can't be reduced with a cat.
The newer cars already have good exhaust filtering systems, its the politic and the politicians that are pushing the EV for their own benefit, in ten years from now used batteries will pollute the earth more rapidly than the ICE
Cos we are fucked for fuel as well. By 2100 no oil coal or gas
Lol This is a wonder invention.l but why euro 5 further reduces Nox if catalytic already dissolve noX
When H²O be our fuel, we don't need CC
17:40 ⚠️ Car Jerks Ahead ⚠️
That’s a constant warning in EVERY city, catalytic converter or not.
Please upload electric vehicles related to technical videos
Cat delete is prohibited mainly in the western world. Thanks lord.
let's get rid of diesel engine and we will reduce our pollution by half
Con's: The price of the product will double, triple or more.
This has to be the dumbest comment on the internet. You do know that literally everything you consume is delivered by diesel right? Your food is farmed using diesel, moved on diesel trains, delivered to the store using diesel trucks. Do us all a favor and please don't vote. Just stay home and drink your Brawndo.
Ignorance is bliss ... Imagine the horror of actually realising that gasoline engines produce more pollutant emissions compared to diesel engines.
Removing the cat will not help mpg. Anyone who want better mpg should buy a newer car or one that burn less fuel.
It worked up to 1996. The OBD computer outsmarted the DIY.
No shit? Which are your specialized education degree in internal combustion engines? How many hundred of engines did you upgraded as own build in your garage?😂
@@Michael-yi4mc It never worked
@@napraznicul How many tune-ups have you done? I bet I have more videos of me helping cars get better mpg than you.
@@blackericdenice Are you drunk? We are talking about REMAPS/tune, OR effects of a RESTRICTION on exhaust?
Yes i do not make bullshit tune, i do only for my dta from the race car and no very often for few oem ecu's, BUT you just switched from my question to another domain, as was about a HARDWARE DEVICE affecting (or not) how the engine runs.
They suck
I dont like it at all .
