Improve lubrication of the engine compartment
Whether under extreme temperature and pressure conditions, heavy shock loads, or exposure to aggressive chemicals, PFPE lubricants can be applied in a variety of ways to meet designers’ needs and improve engine compartment performance and reliability.
Mascherpa specializes in finding PFPE lubrication solutions through its partner Krytox. In this article we will look in detail at the lubrication of valves and seals in the engine compartment.
Lubrication of valves in the engine
A key goal for design engineers-and one that has been legislated by governments around the world-is the reduction of nitrogen oxide (NOx) emissions. The exhaust gas recirculation (EGR) valve is an essential engine component that helps achieve this goal.
The goal is to improve lubricant life and ultimately extend the service life of reliable hydraulic valves. If the valve does not open wide enough, insufficient recirculation can lead to excess pollution. If, on the other hand, the valve remains open, the temperature inside the cylinder may drop excessively, reducing engine performance and fuel consumption.
Effective lubrication is again the key to optimal performance, and Krytox™ PFPE engine compartment lubricants have become the ideal choice in the industry, as they resist high temperatures and EGR valve exhaust fumes.
Cost relief
Reliability under harsh conditions is essential to the success of the EGR valve. We can provide lubrication solutions that can cope with temperatures ranging from -40 to 200˚C and strong vibrations. The goal is to improve lubricant life and, as a result, prolong valve life. Working together with various customers, we always propose a specific type of Krytox™ high-temperature grease to solve the specific valve problem. This improves reliability and optimizes maintenance costs.
Lubrication of seals in the engine
With an increasing number of components that must work together, gaskets are becoming increasingly important under the hood.
This is why the seemingly simple O-ring has become so important and why, once again, lubrication has become critical to its efficient installation and operation.
Lubricants are often applied to keep seals in place and undamaged during assembly. The right choice is critical. The wrong lubricant could degrade the seal, causing premature damage. The preferred choice of many automotive engineers are Krytox™ PFPE lubricants because of its compatibility with all sealing materials. In addition, Krytox™ lubricants do not oxidize, so they do not contribute to degradation and also have greater temperature stability than the seals themselves. The net result is longer O-ring life and greater reliability under the hood.
