In this article we explore how Krytox lubricated EGR valves reduce engine emissions, increase engine output performance, and save fuel.
Higher Performance in EGR Valves
New CO2 and nitrogen oxide emission targets are shifting industrial requirements. As a result, the need for measurement and control precision in the engine air management system has increased significantly. The purpose of exhaust gas re-circulation (EGR) is to reduce engine emissions, increase engine output performance, and save fuel.
The complexity of the engine air management system requires engineers and manufacturers to precisely optimise the performance of the entire system simultaneously. Consequently, the system’s lubrication solutions must work at high temperatures and, in addition, be compatible with the exhaust gases throughout the life of the vehicle.
The exhaust gas re-circulation valve reduces the formation of nitrogen oxide (NOx) emissions by re-circulating some of the exhaust gas into the engine’s cylinders. This reduces the maximum temperatures inside the cylinder; thus reducing the rate of NOx formation. If the valve does not open enough, insufficient re-circulation occurs and contamination levels can raise. However, if the valve is opened, the temperature inside the cylinder can drop too low, thus decreasing engine performance and fuel consumption. For this reason, Krytox high-performance lubricants are an ideal solution. This is due to the EGR valves having to withstand high temperatures and exposure to exhaust gases.

Thanks to the impressive portfolio of Krytox greases, the lubrication of EGR valves is rapidly improving, increasing their performance. Extensive tests have demonstrated the performance lubricants’ effectiveness in extreme temperature and high vibration ranges. They have shown to improve durability, reliability and performance. Additionally, the lifetime of the valve is extended and costs are saved.
