Should i remove egr

EGR systems will reduce the nitrogen oxide emissions because it recirculates some of the exhaust gases through the engine intake. This process keeps the engine cool while maintaining a strong fuel efficiency profile. This kit installs easily on most diesel engines. Most diesel engines use an EGR valve which develops high soot content over time.

This development blocks proper air flow into the engine while increasing the risk of having a deposit reintroduced into the engine. Installing the software from an EGR delete kit will bypass this valve, which will work to restore power to the engine. Most kits will help diesel engines begin performing close to their original results immediately.

You can improve your fuel efficiency with an EGR delete. That makes the process more efficient while reducing the risk of a diesel particulate filter failure. This kit can lower the temperature of your engine. When the coolers or valve of the EGR system get clogged with soot, then the exhaust gases begin to circulate more often in the system.

This blockage causes temperatures to rise around the engine. The advantages of an EGR delete are more for people who intend to tune their car, thus making software and hardware changes to increase engine power. Not only will it help your consumption and power, but at the same time, it can create problems for your engine. With EGR having a well-defined role, some cars that have a more complex suite of sensors can give random errors and, in time, can affect other components vital to the optimal operation of the engine.

EGR delete can therefore create problems, even if the car is older, without DPF or sophisticated sensors.

Some drivers have reported a large amount of smoke coming out of the exhaust after canceling the EGR, strange noise, like the sound of a vacuum cleaner, when the car was accelerated, or even other more serious engine problems, for example, temperature sensors went nuts when the engine was running for longer periods in summer. The answer is yes. You can receive fairly large fines if you are caught having your EGR canceled. In older engines, there is a way to make room for the clean air to go into the combustion chamber.

With the help of this clean air trick, you can feel more horsepower in the engine. A diesel engine normally cools the exhaust gases and re-circulates them into the system. However, bypassing the feature using an EGR delete kit makes the exhaust to remain hot.

That increases the temperature of the exhaust gas and affects the overall efficiency of the engine cooling system. When you bypass the EGR system using a delete kit, you take advantage of the situation if the valve or coolers are clogged. However, if the system gets stuck in an open position, then the EGR can go very bad. If the vehicle works fine at high RPMs or high speeds but struggles when idling with it, then the EGR delete kit will not remedy the situation.

It may be what you need in your vehicle, but it presents its unique set of limitations. You may clog the EGR system due to soot recirculation just as the valves and coolers get blocked as the vehicle operates. EGR delete kits usually come to mind when dealing with older diesel engine vehicles. The design issues in the earlier generation products allowed a bypass to create space for clean air inside the combustion chamber. Theoretically, better air gives you a more efficient power source.

Unlike older engines, modern diesel vehicles struggle to take benefit from this due to design change. That means you might have to work with less horsepower when using an EGR delete kit. In most U. The kind of vehicle you drive and the amount of time you drive it may also affect the fine amount. Using an EGR kit might cause some engines to start knocking after completing the modification work.

The issue may be caused by the change in the temperature profile of your engine. I do a lot of miles and you can always tell which car has had EGR deleted as they absolute stink if your following along with huge clouds of s te.

CarAbuser posts 95 months. The main reason for getting rid was to prevent crap building up in the intake. I cleaned the EGR valve and intake manifold after and also took the time to pull out the swirl flaps.

Car drives better smoother and more responsive , uses less fuel and no longer requires periodic EGR valve cleaning. Edited by CarAbuser on Friday 2nd February Bert Cheese posts 63 months. I've done this to my last couple of cars after resolving swirl flap problems not helped by them being covered in the black stuff, they have both run much better afterwards too with previous low speed juddering in traffic having completely disappeared.

Equally removing it is anti-social, increasing as it does the NOx emissions and as EGR actually improves fuel economy although presumably that's when working and not clogged up!
