Should I block or remove the EGR valve?
Don’t Block or Remove the EGR Valve, It’s Saving You Money. The EGR Valve (Exhaust Gas Recirculation) valve is found on almost all modern engines and is considered part of the emissions package of your vehicle. In some states, removing it will cause you to fail your emissions inspection.
Is the EGR bad for the engine?
It is true that the EGR recycles exhaust gas through the engine and those gasses are less than optimum for combustion. However, at low throttle angles your engine isn't struggling to make power so much as it is struggling to work against the vacuum being created by the pistons traveling up and down the bore. What do I mean?
What is an EGR system?
York, Pennsylvania. Egr stands for exhaust gas recirculation and it is a federal standard for emissions. It takes some exhaust and reintroduces the exhaust back into the engine in a miserable attempt to burn gas that wasn't burnt the first time.
Should I block the EGR on a hybrid car?
Building and recycling a eco-friendly hybrid vehicle has a far bigger carbon footprint than a naturally aspirated 1960/70 V8. Block the EGR off it will not do any harm. Pieter Kemp. Home built Blapsie caravan. There is a definite performance gain under 2000 rpm. Most of the vehicles developed in other countries are built to last only for 2 years.

What does blanking an EGR valve do?
Once the valve is either removed or blanked off the vehicles ECU will no longer get a signal from the EGR Valve causing the emissions workshop light to appear on the dash board. We can remove this by reprogramming the EGR software on the ECU.
What happens if EGR is closed?
Knocking noises from the engine can be caused if the EGR is constantly closed. This is because at low rpm the fuel ignites early when it meets the high temperature. Detonations are also common as a second ignition can occur after the normal ignition.
Is it worth doing an EGR delete?
Removing the EGR valve is going to improve the efficiency and performance of your vehicle and it is going to be a lot more powerful. The EGR valve, while a well-intentioned design feature is impractical in the sense that it sacrifices the performance of the engine in order to ultimately work against its own goal.
Does removing EGR increase power?
When you delete a vehicle's exhaust gas recirculation (EGR) system, it automatically boosts oxygen density in the engine's air/fuel mixture. This will further result in increased horsepower.
Can I just unplug my EGR valve?
Go ahead and unplug it. It won't hurt anything, I promise, except give you a check engine light which you can reset later.

Available. This means less fuel is needed to maintain the same power available from the engine 2.
Can car run with EGR disconnected?
Yes it might affect the environment but no harm to engine as such. there are people who are running without EGR for more than 50k km. Also in all remapping they disable the EGR. There are some doubts on temperature increase in cylinder if EGR is disabled.
Does EGR delete damage engine?

Is the EGR valve normally open or closed?
The EGR valve is the main component of the EGR system and it's normally closed. It connects the exhaust manifold to the intake manifold and is controlled by either a vacuum or a built-in electric step motor.

I've just blanked my EGR valve off... - Page 1 - PistonHeads
Just a question, I notied on some plates there was holes drilled in them [for the 16 valave] but no plates available for the 8 valve which is a different shape so I made one with small holes in it.
How does EGR valve work?
Anyhow, The EGR valve also helps your engine by richening up the air/fuel mixture but without additional fuel. It does this by reducing the amount of oxygen in the cylinders and thus the amount of fuel needed to keep a sane engine temperature while at cruising speeds. This reduces the amount of fuel your engine needs to burn when power demands are ...
Why does the EGR valve open at throttle?
In reality, the valve opens at small throttle openings and in closed throttle situation to help fill the cylinders that are hungry for air but aren't getting any due to the throttle being in the way. It is true that the EGR recycles exhaust gas through the engine and those gasses are less than optimum for combustion.
How does exhaust gas work?
By providing the exhaust gasses to the engine, it's almost like opening the throttle up a bit more but without producing more power/burning more fuel. You're filling the cylinder, which has to be filled with something, but now you're filling it with a small mix of air/fuel and basically do-nothing gas. This reduces wasted energy and nets a gain in fuel economy.
What is an EGR valve?
The EGR Valve (Exhaust Gas Recirculation) valve is found on almost all modern engines and is considered part of the emissions package of your vehicle. In some states, removing it will cause you to fail your emissions inspection. Unfortunately, there is a huge misunderstanding about it's function circulating around the internet and sadly a lot ...
Does EGR make a car faster?
However, in normal mode, you can give the car more throttle in 5th gear without it shifting down thus saving fuel. It doesn't make the car any faster, it only changes the downshift behavior when you get it more throttle. Anyhow, The EGR valve also helps your engine by richening up the air/fuel mixture but without additional fuel.
Does an engine have to work against itself to pull air in?
Therefore, the engine is actually having to work against itself to pull air in and that's wasting energy ("pumping losses"). This is just a design "flaw"/feature of the modern internal combustion engine and there's not a whole lot that can be done about it. However, the EGR valve allows us to do something very clever.
Can you remove EGR valve?
In a street car, you absolutely want to keep it. There is no performance advantage to removing it and the only thing you'd accomplish is wasting more fuel.
What does EGR stand for in exhaust?
I see quite a few of you have blocked off the EGR (Exhaust Gas Recycle ) system. I think I understand what it is, and how to block it off, but I am a little fuzzy as to why you would want to do this.
What is the maximum EGT for a turbo?
This in turn means higher Exhaust gas temps. The maximum EGT you want is about 720c, after which the turbo will begin to self destruct.
How long does a 2000 rpm engine last?
There is a definite performance gain under 2000 rpm. Most of the vehicles developed in other countries are built to last only for 2 years. Recirculating burnt carbon particles act as an abrasive and shortens engine life. It blocks the inlet system and thus affects performance.
Can you reinstall EGR on Scorpio?
If your vehicle is under warranty though, then Henris suggestion will work, as if you cut the plates correctly, and reinstall the EGR system, the dealer won't know. The engine management light will not come on either way.
What does EGR mean in a car?
Egr stands for exhaust gas recirculation and it is a federal standard for emissions. It takes some exhaust and reintroduces the exhaust back into the engine in a miserable attempt to burn gas that wasn't burnt the first time.
Is recirculated gas inert?
You're both close (with Guilty being 99% of the way there). The recirculated gas can be thought of as being inert in that it has already been burnt. By using up some of the space, the temp is kept down in the cylinder. Burning cooler produces less NOx, which is something that causes acid rain.#N#In a nutshell, engines that are matched to their current use are the most efficient and produce the least nasty byproducts. Your engine can't shrink at idle, so they effectively shrink it by filling part of it up with inert gas.
Can exhaust gas be burned?
For those who think unused exhaust gas is being pushed through to be burned all the way you are dead wrong. It takes hot exhaust gases and puts them into the intake to keep temps at idle high enough to burn the fuel in the most efficent way.
Does EGR increase efficiency?
A properly operating EGR can theoretically increase the efficiency of gasoline engines.
