Lubrication Diagram of an engine using pressurized lubrication Wikimedia Commons has media related to Internal combustion piston engine lubrication systems. Surfaces in contact and relative motion to other surfaces require lubrication to reduce wear, noise and increase efficiency by reducing the power wasting in overcoming friction, or to make the mechanism work at all.
At the very least, an engine requires lubrication in the following parts: Between pistons and cylinders Small bearings Big end bearings Main bearings Valve gear (The following elements may not be present): Tappets Rocker arms Pushrods Timing chain or gears.
