I've done mine recently on a garage in my local area, they done it from ECU software and they said I can revert it back easily because they only done some parameters for egr, but now after this something is wrong because my engine is pinging or knocking sounds, particularly during acceleration on heavy load, I think they forgot to adjust from ECU the flow mixture between air and petrol/diesel like you said 😢 what can I do now..some advice please 🥺. Thanks
A properly working egr INCREASES mpg. It adds inert gas while cruising so less fuel is added due to less oxygen. Therefore, the throttle plate has to be opened slightly more which reduces pumping losses. At full throttle the system is DEACTIVATED therefore peak engine performance is not reduced.
Exactly. EGR is poor man's cylinder deactivation. It reduces throttling losses and improves fuel economy by about 5% at cruising speed. And way simpler.
Bought a 2016 sprinter van that already had the delete done (legal in my province in Canada) can gets amazing fuel economy for its size 10L/100km~. Motor should last nearly forever…
Kinda sus that EGRs are legal in your province. Which one? Surely not Ontario? I'm in Alberta; no idea if it's legal or illegal here, but I feel like it should be illegal, lol.
@@Prohortico hot damn. I'm in Alberta as well. Do you suggest I delete my EGR in a 2008 Dodge Grand Caravan? I'm good either way, but I do know that my EGR is probably clogged up nicely at the minimum. Thanks for getting back to me!
Its not simple: block flow, and you throw a p0401 code: the "insufficient flow" is actually driven by low temperature in the egr unit while accellerating and with the check engine light on... you just went blind to other problems you might like to know about. A discrete delete is a nuanced project: create a signal board that can mimic temperature sensor response in the approximate 2400 to 3500 rpm range where an agr is active and do it in real time. And as you point out, fuel curve then has to be re-tuned.
Brilliant! Thanks for the clear explanation. Think I`ll stick with legal side here in the UK. But that`s an individual choice so each to their own. Good luck everyone!
Egr is a terrible design. It's so stupid. It causes cars to run ultimatley worse, consume more fuel and break, I thino that's worse for the environment in the long term.
EGR reduces throttling losses at part load and increases fuel economy while decreasing the hydrocarbons necessary in the exhaust to reduce NOx in the 3 way catalytic converter.
I drive a Hyundai Santa Fe 2.0T. The exhaust system of my car gets clogged frequently because I only drive 4 miles daily. Would deleting the EGR help with the exhaust problems? I live outside the US.
Yes. Your engine never gets hot enough to burn it out. It never really gets hot enough to ever clear it when you do get the motor hot. I don't want to void my warranty or I would do it now. As soon as it's up, it's getting plugged. In a cummins you can let it in tact while buying a kit that can plug the in and out of the egr. This gives it the appearance of the system, but it doesn't function. Just somthing else to think about. When these diesels were mandated to use Def or that blue stuff for emissions, a lot of politicians got richer. It's literally the same stuff we spray on fields called urea, aka nitrogen. We know this isn't about saving the planet because it chemically turns the carbon that would just fall to the ground and turn into dirt, into methane. They say methane is a more potent greenhouse gas. Now why would they want to do that?.... I know several people who took all emissions stuff off their cummins powered trucks. They increased their mpg from 18 to 24 while increasing the power.
I guess you are talking about diesel engines, as EGR is not common in otto circle. Diesel engine do not knock from a lean condition, this is exactly how they control power generated, inside the operating range, more fuel, more power, less fuel, less power...
Zdravo imam 2.0hdi i imam dvije metalne plocice da ga “izbrisem” dali te plocice samo stavim izmedu da ga blokiraju ili da ga fizicki odstranim te montiram plocice ?
Zdravo, Morate da uđete u kompjuter automobila i modificirati ga tako da zna da ne koristi egr. Ako to ne uradite auto ce imati problema zato sto ce misliti da je egr blokiran. I ne samo to, kao rece gospodin u videu, ako ne napravis update kompjuteru auta, neces dobiti vise snage zato sto motor nece znati da da vise benzina autu
PCM knows if engine gets to much air through the O2 sensors and will adjust the fuel accordingly. Plus there is a MAF sensor, MAP sensor so lots of ways to determine the amount of air in the engine. Just replaced my EGR with a cheep one and after a while my Ford gets limited to 3000 rpm (with EGR codes) so thinking of deleting the sucker.
Not necessarily. Older cars had a hard time getting a "lock" on the exact exhaust flow in the EGR. Late 1980s and early 1990s Honda Accords would plug EGR valves, run lean, and burn exhaust valves.
your explanation on engine knock is out wrong, cars are equipped with knock sensors on the engine too correct this. pumping exhaust gas into back into your intake does nothing more than carbon up your engine. the carbon monoxide within a month turns into carbon dioxide which plant's grass and trees use it a food.
@@xothuggerI suggest watching EGR video on "driving 4 answers". EGR actually improves efficiency, but not on high milage, badly serviced flogged cars...

i like this guy explains pros and cons very well in all his videos 👍
worse emissions but better milage surely can help the environment and also wallet

Nice...looking at similar for our 03 Sierra...and a different type of operation on our Cummins.

Removing EGR may cause engine knock. I also don't want pumping loss I will keep my EGR.
Is you engine a diesel ?

Very nicely done! Thank you for the info
Is the egr the same as the sai
No, SAI pumps in fresh air into the intake, before the cat coverters, to warm them up more quickly. SAI only works on warmup.
@@MechanicBase thank you 👍
@@MechanicBaseWhat does the "SAI" acronym stand for?

engine run hotter when egr delete

You fail to mention that deleting the EGR can also cause significant damage to the turbo
I’ll care about emissions when the government puts them on all their vehicles
Justice: Just US!
They are on all government vehicles except some military vehicles.
Will deleting egr cause smells in the cabin ?
It shouldn't, if it's done properly.
@@MechanicBase complete removal ? Blanking plate ? Obviously need to let the system know it’s been done
Only if you fart
It's mostly you!
Factually not completely accurate.
How come?
