A crankcase is the housing that encloses the crankshaft in an internal combustion engine. It serves as a reservoir for engine oil and provides support for various engine components. The crankcase also plays a key role in protecting the engine parts from external elements and helps maintain the proper operating temperature by facilitating oil circulation. It is typically made from aluminum or cast iron for durability and strength.

Etymology

The term 'crankcase' originates from the combination of two English words: 'crank' and 'case'. The word 'crank' comes from the Middle Low German word 'kranke', which means a bent or twisted limb, and it refers to a mechanical part that converts rotary motion into linear motion. The term 'case' has roots in the Latin word 'casus', meaning 'fall' or 'event'. Over time, 'case' evolved to signify a structure that protects or contains something. The use of 'crankcase' became prevalent during the early development of the internal combustion engine in the late 19th century when engineers needed to describe the component that houses the crankshaft and regulates oil distribution within the engine. As automobile technology advanced, the design and function of the crankcase also evolved, yet the term has remained in use as a fundamental part of automotive terminology.
