The cylinder liner or sleeve or bore provides the engine with the cylindrical structure needed to confine the combustion gasses and to act as a guide for the engine’s pistons. In engines using sleeves, there are two types of sleeves, wet and dry.
A piston is a cylindrical engine component that slides back and forth in the cylinder bore by forces produced during the combustion process. The piston acts as a movable end of the combustion chamber. The stationary end of the combustion chamber is the cylinder head. Pistons are commonly made of a cast aluminum alloy for excellent and lightweight thermal conductivity.
This is an e valve for the Isuzu FVM and FTR model trucks. Integral to the vehicle’s engine management system, the aptly named exhaust gas recirculation valve, or EGR valve for short, recirculates finely metered quantities of exhaust gas to the engine intake system for increased engine efficiency, reduced fuel consumption and lower NOx emissions.
