This is WITHOUT A DOUBT THE BEST EXPLANATION about the EGR! All the other videos ive seen only focus on the egr recirculating exhaust gas into the intake, but they never explain why, what for, the way it all operates. This video COVERS IT ALL! I could honestly say that i was one of those who considered the egr a dumb idea and question what it was for. THANK YOU FOR THE VERY INFORMATIVE VIDEO!

This is the best explanation on KZfaq . Better than any Aussies or US video . You should do more of these videos . Keep it up !!

Ive watched at least 10 videos on EGR and NOTHING has explained it with so much clarity as you have. I feel I fully understand it and other things now regarding engines, such as pumping loss which I have never heard before today. Subscribed INSTANTLY 🏆

You should be a teacher if you are not already.absolutely brilliant video explaining everything including pros and cons.even if 1 person benefits and is educated your work sir is a triumph.education is empowerment and you have empowered already 60k plus people.bravo may you keep helping people and get your just rewards.

I doubt anybody could be bored with such a well presented and comprehensive explanation of the workings of the EGR valve, up until now I had no idea it was so complex and desirable. Thank you for this video I'm subscribed and about to further educate myself with your help

Dear Sir, you are easily the best mechanical teacher I have come across on youtube. Thank you for this amazing demonstration. God bless!!

Your demonstration with the blow torch is brilliant. Nice job, sir.

Yes! Thank you for mentioning pumping losses in relationship to the EGR. Clear explanation and demonstration, excellent! Well done. Love the little throttle moving from underneath the sheet of paper, nice🙂

mechanic here , this guy is correct, also D4D hilux/prado etc pistons crack due to high engine load (full power up a hill towing a caravan example), hot piston ,cold fuel shot at piston.......so if you can lower the combustion temp you improve the chances of pistons lasting. so EGR needs to stay. sadly it will soot up the intake but there are ways to mitigate this. im sure ill get critics but its true (i wish it wasnt haha)

I have been a heavy duty diesel mechanic for over 30 years now. None of the emissions changes they have made have given trucks better fuel economy. But like he mentioned deleting the egr system greatly effects the combustion temperature. I have seen many deleted engines and they are know for cracking the head due to higher temperatures.

Absolutely excellant coverage of the EGR system, your methodical and measured approach to teaching your subject is phenomenal! Thank-you, well worth the time spent!

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

Brother...that was so to the point..and informative...I watch Chris fix, Scotty , a handful of other vehicle diagnostics and repair channels..dude that was delivered in a manner that I have to say is one of the easiest to get a good mental grasp of the egr system..the illustrations the slow pace.. the constant explanation of everything mentioned previously. ..dude you got a like and subscribe today...id rank this video up there with a few of my favs from project farm...so yeah. Um guess I'm about to binge watch the rest of your videos until the Dallas cowboys game comes on. Thanks boss

Woah ,if you don't understand will never understand. What a top notch explanation and details. Superb. Very smooth and a calmly way no background music ,I really enjoyed and learned from it.Thank you for your precious time and effort. 😊

No one has explained this better! Great job!

The views on this video should be in the millions, Thank you for a brilliant explanation.

I'm glad I found your channel! Excellent explanation on DIY projects! Waaaay better than channels with larger followings!

One of the best well presented videos I’ve seen on this platform. Thank you!

Absolutely fantastic! So clear and unhurried and captivatingly well explained. Best “How it works” video I’ve ever seen. Thanks so much for taking the time to put this together. Huge thumbs up! Regards Guy

Absolutely mind blown by how comprehensive this video was, thank you!!!!

This video deserves MILLIONS of views. FANTASTIC work here. It's so informative

thank you for that video, honestly, it's the best explanation about the EGR on the KZfaq. your explanation is very precise, I found in this video the information I search for several years.

Man, you’re a master! This is the best explanation about EGR available on YT. Very well done!

This is a great video. I had it explained to me that the EGR cooler was responsible for cooling the exhaust down to less than ambient, which I thought didn't make sense. This explains how the EGR reduces temperature much better

This is the best I have seen to explain how a egr valve works. Very simple to understand. Great job thank you

What an amazing video! You were so thorough! Best video on KZfaq explaining egr hands down, thank you very much

This is probably the best explanation of the EGR and how it works. Very good work. It makes way more sense to me now.

What a great description of how the EGR works. Very interesting and superbly done. Great

Świetnie wytłumaczone . Fajne pokazanie zasady z tym palnikiem 😊

Congratulations for all your explanation, I really appreciate all the content and the examples you provide. Keep sharing great content please. Thank you!!!

Best and most carefully explained account of the EGR valve I've ever watched. You have a new subscriber!

WONDERFUL EXPLANATION!! We know that people know what they’re talking about, when someone who doesn’t understand a thing about these topics, finds it easy to understand.

Brilliantly explained with a clear language! Looking forward to watch more! But when I watch my engine with a OBD-App, I can see, that the EGR is also working in cold engine during idling. No faults in ECU. Greeting from Germany!

Thank you for recording this video. Your explanation was so simple to understand. You explained like a university professor.

Nicest explanation of EGR. Slow, steady and clear.

Thank you! This is by far the best and most comprehensive explanation of the EGR systems in our vehicles! Because of this, I had to subscribe! 👍

Excellent explanation -- clear, to the point, easily understood. Kudos sir!!!

Definitely not bored, this is one of the best explanation videos I have seen.

Mann, you are the best teacher on KZfaq regarding EGR valve....keep up the great work....

Nice explanation, I've been driving diesel cars for taxi for years. my advice, if you don't want endless costs, issues and codes, get a diesel car with less sensors, egr, dpf, adblue, additives and other complicated components that needs the car to be plugged in to figure out what is going wrong. diesel cars only needs service and that's it.

I wasn't even looking for EGR Info but decided to give this a watch based on the rave reviews.. I am now so much richer for having watched this, thanks! One day I might clean my EGR valve.. maybe..

The clearest, most logical lecture on EGR!

Best and comprehensive EGR explanation on the internet so far, kudos to you sir and tvm!

Very well explained about the egr system 👍 I have a 1KD-FTV 3L turbo diesel and what I did after removing and cleaning the whole intake system was put a blanking plate with a 7mm hole in between the egr cooler and number 1 pistion intake . This still allows the egr to flow at a lower rate sloweing down carbon biuld up with no codes coming up 😊 worked 4 me .

Subscription earned. You have a gift for clear and concise teaching with excellent physical demonstrations.

Extremely thorough explanation. Thanks for taking the time to do this 👍

This is by far the simple and very understandable explaination i ever came across

Thank you for taking the time to help me understand the EGR system. That took a lot of time and effort.

Very clear explanation on the EGR glad I found your channel keep up the good work.

After watching so many videos about EGR, this is the only one that I understand. Thank you, Sir!

this guy is a great exlpainer.he never says um,or ah. just flowing fluent educational speech.awesome!👍

Thank you very much , never found a video explaining EGR like yours , simply the best.

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

Thank you Mr DIYer for a fantastic explanation of how the EGR works The best video I have seen on youtube

Dear sir, this is the best teaching on egr. Not every one who knows can explain like you. You are a born professor. Thank you so much.

Second Explorer's comments ... THE ABSOLUTE BEST EXPLANATION about the EGR. Thank You Very Much for SHARING THIS VERY INFORMATIVE VIDEO !!!

This egr explanation is absolutely brilliant.

There was this KZfaq channel (name: Garage 54) that tried to make a separate engine run on another engine's exhaust gas and managed to make the engine work.

這個影片是解釋EGR 最佳的影片，太讚了!!

thank you for your clarification about this information, I was confused before I watched your video

Wow thank you for this. Really informative. I was a bit reluctant to watch because 20 minutes seems long... but it was worth every second. Well done!

Best video on you tube explaining what an egr valve does Credit to you sir and thank you.

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

Thank you! This is the best explanation I have ever seen on EGR. I would be curious to hear your opinion about swirl flap delete as well

ang galing magturo! veryinformative and straight to the point.

Kudos sir! Hindi man lang ako inantok. Mas naging attentive pa tuloy ako. More power sir!

Great job! You thoughly explained the EGR in simple terms! Thks so much!

Brilliant! clear and comprehensive explanation

This the best EGR explanation video ever !!

This is amazing! Thank you for your work! Edit: initially commented to ask about the pcv system, but I found your other videos.

Im not bored. So informative. Thank you so much for giving time for this videos.

very well done! even a non-mechanic like me will understand the function of the EGR system function. Thx, Ant.

Wow That's a precise explanation by an engineer.

Mate that was bloody awesome u should get a award so clear and easy to follow love it thanks heaps keep up the great work mate

Crystal clear explanation Mr. DIYer. Thank you very much.

This is a whole EGR masterclass. Liked and subscribed ❤❤❤

Just wow Sir, very good explanation, thank you!!!

You are great at making people understand Sir.....and that too without any cost

To show you how wonderful your explanation is, my graduation project was based mainly on this video. You made things easier for me, thank you🌹.

Excellent video, Sir! Clear and comprehensive.

Your videos are amazing! Very easy to follow and great depth in the explanations. However, I would argue that during startup egr helps to get the (diesel) engine up to temperature quicker. @09:30

Brilliant simple explanation, great video thanks for taking the time to make it.

That was brilliant. Learned a lot from that.

That explains exactly what was happening to my Ford Transit. Started knocking noice and low power after not a great amount of miles. Still a young motor. Still went but slow build up to 100kilometers. Had i seen this awesome video earlier. I would have cleaned the EGR. I literally wrecked the entire vehcle because of it and sold it as parts.

Perfect explanation and well paced. Superb work 👍

Ma dude, this is the best egr video on KZfaq. Thank you for that. Subscribed!

Really like your style and enjoyed this very informative video. Before this I only had a very vague idea of what an EGR does.

This is a fantastic video, one of the best I've seen on youtube on any topic.

This is awesome video with great real world examples and analogies.

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

I really needed to see this, I was going to remove my egr on my diesel. Thanks.

Very clear and properly arranged sub topics with supporting technical facts great mabuhay ka sir DIYr

Brilliant explanation of the EGR valve.... Great visuals. 100% 👍

Chef's kiss. Great explanation!

For me, This is so far the best explanation

Best video i have seen for EGR on KZfaq

You are a very good educator clear concise and understandable thank you for your explanation

An excellent video, couldn't ask for more. Superb!

This is one nice lecture of an automotive technology.more videos like this please.!

Finally I understand how and why of things. Thank you sir!
