![]() The only solution to this issue involves having a new gasket installed as soon as possible. Although EGR gaskets consist of heavy-duty and heat-resistant materials, they may develop cracks and other problems as time goes on.Ī damaged EGR valve gasket potentially allows exhaust to leak into your engine, even when your EGR valve remains in a closed position. By replacing your air filter, you should not only restore an ideal air-fuel ratio, but also the problems associated with excessive EGR system flow.Īnother common cause of excessive EGR flow has to do with the gasket used to create an air-tight seal between the EGR valve and its mounting surface. An overly dirty filter restricts airflow into your engine, often leading to rich fuel conditions. One of the most common culprits here has to do with your car’s air filter. As a result, the EGR valve will remain open even at times when it normally wouldn’t. Rich fuel conditions – in other words, too much gasoline relative to the amount of air – means that more fuel than usual will escape your engine unburned. Unfortunately, this function can end up leading to problems for engines whose air-fuel ratio gets too far from the ideal. Your EGR system promotes fuel efficiency by recirculating this fuel through your engine a second time. Instead, some unburned fuel escapes from the engine along with the exhaust. Yet few engines can achieve this result in real life. In a perfectly balanced engine, air and fuel would mix together in such precise proportions that every last bit of the fuel got burned up. To prevent build-up from affecting the performance of your EGR valve, most experts recommend having your EGR valve cleaned and inspected about once a year. The excess flow of exhaust dilutes the amount of oxygen available in the air-fuel mixture, leading to rough idling, misfires, and even engine stalling. Soot and other byproducts found in your exhaust can build up to such an extent that the valve cannot fully close. This issue almost always stems from the accumulation of problematic deposits on the valve body. Yet if your EGR valve becomes stuck in an open position, it cannot prevent exhaust from entering the engine. Your car uses information provided by its sophisticated sensor system to determine when – and for how long – to open the EGR valve. In order to optimize performance, an EGR valve allows exhaust to enter your engine at some times while preventing it from doing so at other times. This article outlines three frequent causes of excess EGR system flow. If you would like to learn more about what can cause this problem, keep reading. ![]() In some cases, the system may allow an excessive amount of exhaust back into your engine. ![]() Ultimately, EGR systems promote cleaner emissions and better fuel efficiency.Īs time goes on, however, an EGR system may develop problems that hinder it from providing the correct results. Such recirculation eliminates many toxic exhaust substances and also provides vital cooling to your engine. This system routes a portion of your exhaust gases back through the engine. Most cars produced in recent years contain an exhaust gas recirculation system or EGR system for short. ![]()
