Exhaust gas recirculation (EGR) made easy

EGR= it like breathing through a tube that is in the ass

BIGGER CARS with SMALLER ENGINES working HARDER don't last.

ALL OUR LIVES we are told the IMPORTANCE OF CLEAN AIR FILTER for engine longevity.
then manufacturers DIVERT ABRASIVE/ ACIDIC SOOT back into the cylinders which GUMM UP RINGS, abrade bores and ACIDIFY OIL.

Cooper grease the EGR ❤?

The EGR has aluminium components?

Vielen Dank

But some mechanic remove the EGR, maybe not understand the function. Like my engine of my Suzuki multicab f6a scrum.

Can egr malfunction cause a misfire ?

It’s a old inefficient system in my opinion, yes it keeps engine temps low, good for a old Tahoe an it’s little clutch fan in the summer, but choking out the motor is no fun. There’s better methods, I’m removing mine😂

what an honest video

So basically the EGR valve is a way of the vehicle giving itself a Dutch Oven.

Been around since the 70s and still can't get it right

The environmental aspect of reduced NOX emissions is all well and good. Unfortunately all these parts eventually clog up with soot and are usually in difficult to reach positions, making removal and cleaning a difficult and/or expensive job. Same with the DPF - Great idea when it's working, expensive to fix when it doesn't!

Worst whats can happen to engine. Cloged intake, stucked egr valve. Its evil

If reducing o2 is great for low nox, then why not just run with closed throtle and rich mixture....

Just did this on a VW TdI. These engines suffocate themselves and in the long run, they than pollute and consume more fuel than necessary because of the wear. Ingenuity and complexity at its finest. Thx politicians and environmentalists! May you inhale your own farts!

Egr is scam... The manufacturer makes this money making machine.. it cost a lot to clean and replace the parts.

And also significantly reduces the life of your engine.. They love that part to .

I really have a hard time understanding this concept! We take warm hot exhaust gas and put in into the cold intake air, to cool the combustion chamber so it reduces nox? I find that like trying to cool your freezer with a blow torch?
Also we take exhaust gas and take it into the intake to lower O2 levels?! To reduce CO2?
Well how do that work? If you lower the O2 level, the engine would want more air to make the lambda burn fuel near stoikiometric?! Hence doing this would reduce the engines output and wasting the efficiency? It makes no sense to me why you would do this or going this way to solve a problem.

Doesn’t it reduce carbon monoxide, not carbon dioxide?

Why are the manufacturers fitting these egr valves if they are clogging up with carbon causing the vehicle owner to fork out thousands of pounds to get a replacement only for it to happen again in let’s say another 56k mileage a but yet the DPF has a system that does a reg.

Learning functional tests, EGR is part of the test in some vehicles

EGR is easy to explain..... Go for a run around the block, and notice how you feel. Next, take a flexible tube. Put one end in your nostril, and stick the other end up your bum hole. Again, go for a run around the block, take notice of how you feel

Thank You!❤️

i have a ford ranger 2009 2. 3 with a P0400 code. the egr aparently is in a place where i cannt even see it at all.

Great explanation of a shameful wicked system.

Stupid idea of having EGR. Engine has less power, intake mainfold is incredibly dirty, costs of service is higher and there's a need of cleanIng EGR and throttle body constantly. I removed it and no issues.

Racepipe and full egr delete. The way to go for

Nice clarification...

Basically an EGR valve forces the engine to smell it's own farts.

What they don't tell you is that particularly in diesels, it reduces fuel economy which in-turn increases fuel consumption. I also increases engine wear and reduces engine life. If the EGR or EGR cooler fail (which they do often) they can allow soot into the cylinder which can coat the cylinder walls and damage them or the piston.

Glad you included both gas and diesel engines, since I have one of each.

egr is the biggest bs on my car. Folks at the garage told me to sometimes run the car 30mins @3500 rpm at least, to burn it clean.
It would clog up anyway.
It made the car run poorly.

I'm not mechanically inclined on this stuff but would exhaust gases be recirculated through a oil catch can if installed?

How much emissions are spent to build me a new engine when mine goes out because it was literally eating it’s own waste and gave up at 100k miles?

ขนาดเครื่องเจตยังมีแค่ EGR เลยครับ
เสมือนบู้ทเตอร์แระ

EGR - what makes cars less fun, repairs more expensive, bureaucrats happy.

This reduced milage by 20%

Bypass valve actuator supply and electronic details

Great video. Simple explanation - easy to understand. Great CGI. Very well done. Thank you!!

Great vid but FUCK egr

Everyone one that commenting things about how these make your car perform worse... Unless you all driving 40 year old cars - This is just not true. Do your research, stop reading random forums full of car guys who don't even know what they're talking about.

saving fuel vs spending money for spare parts

Nice video

Hippy pleasing crap

I refuse to believe that the recirculated 500 *C Exhaust gas can cool the combustión chamber

I used to always install a plate under the egr valve, blocking it's function. Used to! I now do the opposite, i "block" the egr valve open permanently, this allows me to advance the ignition timing substantially, so that i get a lot more power out of a lot less gasoline, without any knocking or pinging.
