Modern engines rely on advanced exhaust gas cleaning systems to reduce harmful emissions and meet strict environmental standards. These systems include components such as EGR valves, coolers, and NOx sensors, which work together to improve combustion efficiency, lower NOx levels, and protect the environment. At Wilmink Engine Parts, we supply high-quality exhaust gas cleaning parts that meet OE specifications and provide reliable solutions for overhaul specialists and wholesalers. |

Exhaust Gas Recirculation (EGR) is a system that routes a portion of the exhaust gases back into the engine’s intake. BBy reintroducing exhaust gases, combustion temperatures are reduced, as the exhaust gas is inert, thereby reducing the formation of nitrogen oxides (NOx).
The EGR valve controls the amount of exhaust gas recirculated into the intake system. When functioning correctly, it helps maintain an ideal balance between performance and emissions.
To check an EGR valve:
An EGR cooler (heat exchanger) lowers the temperature of the exhaust gases before they are redirected into the intake. Cooling the gases helps further reduce NOx emissions and prevents excessive heat in the intake system.
An EGR delete is the removal or bypassing of the EGR system. While sometimes used in performance modifications, it is not recommended for road vehicles. Deleting the EGR system increases emissions, may cause engine issues, and is not compliant with emissions regulations.
NOx emissions are nitrogen oxides produced during high-temperature combustion. They contribute to smog and environmental pollution. Systems like EGR valves, EGR coolers, and NOx sensors help reduce these emissions by controlling combustion conditions.
At Wilmink Engine Parts, you’ll find OE-quality exhaust gas cleaning components from trusted manufacturers:
Both brands are recognized for their engineering quality, helping overhaul professionals and wholesalers deliver dependable solutions for customers.
The EGR vacuum modulator regulates the vacuum pressure to the EGR valve. A faulty modulator can lead to poor engine performance and increased emissions. Testing involves checking vacuum lines for leaks and using a hand vacuum pump to ensure proper operation.
Yes. An EGR valve gasket ensures a proper seal between the valve and the intake manifold. A damaged or missing gasket can cause exhaust leaks, increased noise, and reduced system efficiency.
Symptoms include:
Replacing the gasket restores the seal and keeps the exhaust gas cleaning system functioning correctly.
Cleaning involves removing the EGR valve and carefully clearing away carbon deposits. Specialized cleaners may be used, but in many cases, replacement of heavily contaminated parts with OEM-quality parts is the most reliable solution.
