We know that you want to get as much energy and use out of fuel as possible, and that engines are more fuel-efficient at higher cylinder pressure. L.E. Jones’ valve seat inserts are made of wear durable alloys and machined to the tightest tolerances to create and maintain a better seal with the valve, thus helping to ensure no combustion leakage. With the current industry push toward fuel economy improvement, cylinder pressure in engines is rising. As you know, this causes higher thermal stress and frictional stress inside the cylinder. Exhaust particulates are also important lubricants to reduce the friction between one material and another. You don’t want valve or VSI wear to increase, and L. E. Jones is in business to keep total wear at an acceptable rate. If you are experiencing increased wear, material changes can be made to manage this wear without needing to employ super-premium materials. Achieving improved fuel economy and lower emissions maintaining durability is challenging, but possible with the right alloys.
