What does EGR stand for?

Within modern internal combustion engines, Exhaust Gas Recirculation (EGR) is a method to control Nitrogen Oxides (NOx) emissions, produced as a by-product during the combustion process.

What are the symptoms of a failing EGR valve?

How much does it cost to replace the EGR valve?

The average cost of replacing the EGR valve in your vehicle is anywhere from $250 to $350 on average, depending on your vehicle's year, make, and model as well as the type of system it has. The cost of parts will be somewhere around $190 to $270, while the cost of labor will be anywhere from $60 to $80.

What does a EGR do on a diesel?

Abstract: Exhaust gas recirculation (EGR) is an effective strategy to control NOx emissions from diesel engines. The EGR reduces NOx through lowering the oxygen concentration in the combustion chamber, as well as through heat absorption.

What does removing EGR do?

An EGR delete kit is an aftermarket performance part that removes the EGR valve and prevents exhaust from being redirected back to the engine. Ultimately, this allows your vehicle to function as if it never had an EGR valve.

Is deleting EGR illegal?

An EGR delete is NOT the end all solution that most claim it to be. An EGR delete is ILLEGAL in ALL 50 STATES. All vehicles are required to meet federal emissions standards. The penalty for an emissions component alteration can be in the thousands of dollars.

Will EGR delete hurt engine?

What some people don't realize is that yes, deleting an EGR system can help prevent some expensive repairs. But they can also cause major problems in other parts of your engine.

Does EGR valve affect Turbo?

The EGR valve is likely to stick and become coked up on some applications. BTN Turbo warns that this can have a significant effect on turbocharger performance. A faulty EGR valve can result in excessive carbon/soot at the turbine end, causing the VNT mechanism to stick.

Does EGR increase fuel economy diesel?

With EGR rates up to 20% a slight increase of fuel conversion efficiency at low loads was observed, explained by re-burning of hydrocarbons that enter the combustion chamber with the re-circulated exhaust gas [30].

Will an EGR delete improve gas mileage?

You can improve your fuel efficiency with an EGR delete.

You may see up to a 20% increase in your fuel economy when using this product option while promoting improved longevity of the engine at the same time.

Can car run without EGR?

It might affect the environment but it is not harmful to the engine. Some people are running for more than 50k km without EGR. The EGR is disabled in all remapping.

Can I replace my EGR valve myself?

In most models, replacing an exhaust gas recirculation (EGR) valve is not difficult. You can do it in your garage in about an hour or two, depending on your particular system, using some common tools and a good solvent like carburetor cleaner.

Is it better to clean or replace EGR valve?

Proper maintenance of the valve is a must if you want to avoid any performance related issues on your car. If you notice a smell of fuel that comes out from under the hood or rough idling, then it might be time to replace the valve. In most cases, though, you do not need to toss it out just yet.

Will a bad EGR valve cause a check engine light?

If the EGR valve fails, the computer will recognize the problem and turn on the check engine light. This part may seem a little pricey, but it's typically an easy fix and will ensure that your engine gets back to running the way it should.

Is it worth cleaning EGR valve?

Cleaning your EGR valve will solve your car's engine performance issues related to any clogging or system passages problem with the valve. Even more importantly, it'll prevent serious engine damage and expensive repairs.

What does the blue smoke in diesel engine indicate?

Blue exhaust smoke in a diesel vehicle could still mean oil is being burned, but it could also mean the engine oil is being atomized. This could be caused by: High engine oil levels. Worn out piston rings.

Does an EGR delete make black smoke?

Registered. From my experience so far blocking or deleting the egr does not reduce smoke.

Where do you spray EGR cleaner?

Spray the product for 2 seconds into the air intake manifold but DO NOT SPRAY DIRECTLY INTO THE INTERCOOLER. After each spray, wait until the idle rpm is restored and engine runs stable. Repeat the process until all of the product has been discharged from the aerosol.

What causes EGR to block?

This is caused by: The EGR valve mechanism is stuck open. The air filter is clogged or dirty. There are intake leaks.

How do you prevent EGR valve failure?

Moreover, many EGR problems can be avoided by simply ensuring that the vehicle is maintained regularly and gets a decent blat down a highway at least once a month, with plenty of accelerating and decelerating (pottering around town at low speeds is especially bad for EGR valves).

Does EGR affect performance?

At lower loads, EGR reduces NO_x without deteriorating performance and emissions. At higher loads, increased rate of EGR reduces NO_x to a great extent but deteriorates performance and emissions. Thus, it can be concluded that higher rate of EGR can be applied at lower loads.

What happens if you get caught with a deleted diesel?

The fines can quickly get out of hand, as the EPA has the right to assess civil penalties of $37,500 per day for significant issues and up to $7,500 per day for minor ones.

Do gas engines have EGR?

External Exhaust Gas Recirculation (EGR) has been used on diesel engines for decades and has also been used on gasoline engines in the past. It is recently reintroduced on gasoline engines to improve fuel economy at mid and high engine load conditions, where EGR can reduce throttling losses and fuel enrichment.
