Crankcase

A crankcase is an integral part of an internal combustion engine. It is a housing that encloses the crankshaft, connecting rods, and other internal components of the engine. The crankcase is typically made of metal and is designed to contain the lubricating oil that keeps the engine's moving parts properly lubricated.

The crankcase serves several important functions in an engine. It provides a sealed environment for the crankshaft and connecting rods, protecting them from dirt, debris, and contaminants. It also helps to dissipate heat generated by the engine, as it is in direct contact with the engine block.

Additionally, the crankcase houses the oil pan, which holds the engine's lubricating oil. The oil is circulated throughout the engine by an oil pump, providing lubrication to the crankshaft, connecting rods, and other moving parts. The crankcase also contains various seals and gaskets to prevent oil leaks and maintain the proper oil pressure within the engine.

Overall, the crankcase plays a crucial role in the proper functioning and longevity of an internal combustion engine.
