EGR Explained! Do we Need to DELETE the EGR?

Excellent explanation, thank you 😃

Everyday we should learn something new, today I did. I learnt that the engine/air shut off is not just to prevent runaway in a diesel engine. With servo motor control, more can be done. My question is though, could older systems with vacuum control modulate the valve/s openings accurately ? Great video, very informative 🙏

Does Diesel engine need a throttle valve? I want to delete the EGR on a BMW e90 320d M47, but the throttle valve is right before the EGR and i want to remove both.

It's the opposite the EGR is open at cold start to get more hot air .

What about restricting the flow on the EGR for the benefit of not having less carbon build up on a diesel.
I'm not sure I understand if the engine is running cooler surely there's more harmful emissions, if it's running hotter these emissions would get burnt off because not all the exhaust gases are recycled, so I can't see thats reducing the emissions by having the EGR?

Bored?? Man, this video was so entertaining. You have talent to educate people. One of the best educational videos i have watched. thank you.

👍👍👍👍

What a fantastic tutorial. Best I have ever seen, thank you very much 🤟

😅

Salamat po!

這個影片是解釋EGR 最佳的影片，太讚了!!

This ficking egr caused my engine to lock up due to carbon residue enter the combustion chamber. There goes the evnironment

Thank you 👍🏽👍🏽

Excellent explanation of the recirculating gas system on the diesel and ICE engine. Thanks for making this so accessible.

Excellent tutorial. Will be looking to get my EGR cleaned.

Excellent work

there is one word for this video. RESPECT!

Well I've had an EGR disabled on my car aswell as egr cooler removed .
What I've noticed is better throttle response. quicker turbo spool up. almost exactly 10% better fuel economy.. no more black smoke from exhaust. Coolant temp doesent run any hotter infact have found the opposite , seems to run a little cooler.
Now have peace of mind knowing that the engine won't grenade from a failed egr cooler. Nor have to worry about spending a fortune on intake manifold and egr cleaning every few years.
EGR SYSTEMS ARE A CURSE ON MODERN DIESELS !!!

Very good and informative. I have a 2.4 Honda CRV, I just cleaned my EGR and PCV valves 2 weeks ago, I was wondering about the EGR cause like you said many people are deleting it, now I will leave it as is, just clean or replace if I have to, the engineers designed a car in a particular way and should not be tampered with.

Good video 💯

Yes it’s still deleted, mainly because I have had a performance exhaust fitted and they recommend leaving it deleted. I have had a few things to sort on the car so haven’t had time to swap it back but once I’ve driven it for a while with the new exhaust and am familiar with how it runs on my regular journeys, then I will swap it back and see if I notice any difference on those same journeys.

sir how about limiting the volume of exhaust gas bybplacing an EGR plate with a 7mm openingvas I've read in some forums?

Best explination ever. THANK YOU SIR!!

&& i thank you with all my honor

Truly an amazing video took the time and drawing to explain well done best video better than what is taught at school

Really appreciate and thanks sir. Good explanation and examples❤️

if you have an throttle valve that does not work would that cause any harm later on to the engine thank you

Fascinating! 😀👍👍

What a great video.Learnt a lot! Thank you.

Best explanation of the egr system to date!

Since EGR reduces pumping losses, does it reduce engine braking?

👏👏👏👍👍👍😃😃😃

Thank you for a very clear information about function of gas and diesel EGR sir👍

Egr will kill your engine slowly,because of carbon deposit inside your intake manifold,its very hard to maintain that.airfilter to have clean air in your engine,but why engineers put exhaust gas to our engine😂😂😂.no way,i already blocked my egr.

Egr is rubbish , better to be simple. They differ cause one is newer than the other

thanks for this, this further clarify to why my turbodiesel 2003 kia sorento gets very sluggish and overheating after long period time of driving/idling (+black smoke and very poor fuel economy when idling/driving uphill road)

my temporary workaround for this is to block off the egr (also, the egr valve body is covered with engine oil) , the sluggish performance after long period driving/idling is still there but not as severe as before blocking egr but no more overheating, i will try to clean the egr later on. ( i also removed the turbo water cooling line before, i think this might be one of the causes as well, i will reinstall later as well)

do correct me if im wrong here.

Thanks!

So you saying pushing hot exhaust gas into you cylinder reduces engine temperature?? BS

It’s absolutely true! Why else would the eye be full of carbon and soot??

💯best explanation I’ve ever had 💯
Wow bet a few who have had a incorrect explanation are thinking 💩

Best explanation video about EGR I have ever seen on Internet !

Man you are very talented. I understand your explanations very well. You know how to explain details. You need to be a teacher.

Eating your own manure. Now THAT'S what I call getting your point across. Good job. Reminds me of the termite guy's video down in Florida who explained how termites love cardboard by saying termites love to eat cardboard, like a fat woman loves chocolate.

Genius ito na paraan para ma double ang gas consumption at madaling masira ang makina. Good business sa mga manufacturer 😅

You may install oil catch can to prevent carbon monoxide sticking on intake manifold .

Excellent presentation, clearly explained and illustrated, more please!

OMG this is brilliant thank you !!!❤❤

perfect. thank you

Yes, most people are correct, egr mean you eat your own sh.t. Egr is the most stupid thing come from the Lawyer! There are ways to reduce emission!
