Egr Valve: What Is It And Why Does Your Car Need One?

In vehicles, the EGR valve, or exhaust gas recirculation valve, is part of the engine management system and is in charge of reintroducing exhaust gas in measured amounts to the intake system. This improves engine efficiency, lowers fuel consumption, and cuts nitrogen oxide emissions.

The pressure to reduce emissions means that the EGR valve will take on a more significant role in the future. In the event that it breaks, you must know what it is, why it breaks, and how to replace it..So watch this video to the end to understand everything!

EGR is like eating your own sh!t to reduce waste 😂

Best lesson learned: the best EGR is the deleted EGR.

They are great for clogging up your diesel engine intake.

I admire and appreciate all the YouTube teaching and learning videos, only thing with this is the man is talking and explaining to fast.

The narrative is so flowing continuously, continuously flowing, flowing continuously without any little brakes/pauses, that my poor brain can't grasp the content !!! After the video, even at 0.75 speed, I don't know more about EGR than I already did understand before.
it could be a good YouTube, but the way it "flows", it is in vain. And if there is something important to read in the video, there should be even more time to "get it", I can't read, while the narrator is talking. After something difficult/complex is explained, the pause needs to be longer!
The combination of pictures, video, narrative, Pauses, reading, and Summary makes a good learning/teaching experience.
After 10 to 15 min Something of the content should stick to my permanent brain memory!

I just spent about $1000 having my EGR replaced in my diesel car. So this is what it was for xD

[jat-justamaturetech-philpj]

How do you know when you need to replace it? Even without codes? Mine is 24 years old!
I'm not getting black smoke. I am having a slight rough idle and murmer when cold. I have new OEM Chrysler IAC, MAP and TPS and all new injectors, Coil, plugs and fuel pressure regulator.

I have a 02 honda accord Se and running rich so I get smell of gas fumes inside the car when the fan is blowing inside the car and also when I press the gas I get a strong fume smell out the exhaust mufflers……so should I change the EGR VALVE?!??

M52 and M54 are practically the pinnacle. Not perfect, but very good.

[Fleshbits]

Is there any danger of coolant making its way into cylinders as a result of busted EGR cooling systems?

[AnthonyTobyEllenor-pijq]

How can the EGR, " improve engine efficiency" ?? I cannot see how engine efficiency can be improved and I am thinking of disconnecting the EGR valve on my car, any comments ??

[marcom]

Just something else to go wrong, with no benefit

[billysaunders]

I find it really difficult to follow these voices

[monkeyboysdad]

I always wonder why the words are read so quickly? It’s just rushed and makes the information harder to understand. Pity really as the graphics are good.

The evidence that we have no right to property, Is evident not only in the fact that we are forced to pay the unconstitutional property tax, but the fact that It is illegal to remove the EGR valve on a vehicle which we own.

[paveljelinek]

Interesting fact: cars without egr have a longer lifespan. So where's your effectivity? In SHIT! There it is!

[Caleb-lbj]

I hate it a can of break cleaner will clean it

Exhaust gas into the intake will not make you waste less fuel he doesn’t know what he’s talking about

[Hardknuckle_LBZ]

EGR valves do not help you get better.Fuel mileage, if anything it costs you feel mileage.It also destroys your motor prematurely And essentially restricts your air flow Especially in diesels. Also the idea That it helps cut down. The exhaust gasses in the environment is also c*** because Yes, exhaust gasses.Go into the atmosphere but guess what Trees and other vegetation Filter the Co two gases and turn it into oxygen Basically trees are The planets air filter All this is a bunch of crap Word of advice delete the EG.R especially if you're going to spend a $100, 000 on a truck Leave the stupid emission systems on the vehicle. Just tune it and shut it off. So you get rid of the check engine light And drive the vehicle and keep your mouth shut about it. Keep a tuner on hand so if you have inspections every year you can turn it on before you go to the inspection. And then once you pass, shut it off again. And again keep your mouth shut. And don't fall into the kind of crap that this video is trying to get out They explained what the function is for. And what the EGR is for. But it's nothing but a bunch of garbage That has no truth behind it
