What is engine crank case?

The engine crankcase is the housing that encloses the crankshaft and other internal components of an internal combustion engine. It serves multiple functions, including providing structural support, containing oil for lubrication, and preventing contaminants from entering the engine. The crankcase is typically made of metal or durable composite materials to withstand the stresses of engine operation. Additionally, it plays a crucial role in maintaining proper engine pressure and preventing leaks.
