Crankcase

A crankcase is the housing for the crankshaft in a reciprocating internal combustion engine. In motorcycle engines, the crankcase is integrated into the engine block.Two-stroke engines typically use a crankcase-compression design, resulting in the fuel/air mixture passing through the crankcase before entering the cylinder(s). This design of the engine does not include an oil sump in the crankcase.Four-stroke engines typically have an oil sump at the bottom of the crankcase and the majority of the engine's oil is held within the crankcase. Crankcase is usually made of metal materials and is divided into left and right parts, which can be replaced during maintenance. There is also a crankcase cover on the outside of the crankcase to cover and protect the crankcase. You can buy the crankcase and crankcase cover at the same time.
