Crankcases are an essential component in internal combustion engines, particularly in automobiles and motorcycles. They are an integral part of the engine housing, serving as a protective enclosure for the crankshaft and other internal moving parts. The term "crankcase" is derived from the words "crank," referring to the crankshaft that converts reciprocating motion into rotational motion, and "case," indicating the protective casing.
The main function of a crankcase is to house the crankshaft, connecting rods, pistons, and bearings, while also containing the lubricating oil required for the engine's smooth operation. It prevents the ingress of dirt, debris, and pollutants that could potentially damage the internal components. Additionally, the crankcase is equipped with various openings and passageways to allow oil circulation, ventilation, and drainage.
Crankcases are typically made from durable materials such as cast aluminum, which provides optimal strength without adding excessive weight to the engine. They are designed with intricate channels and compartments to effectively manage the flow of oil throughout the engine, ensuring proper lubrication of all the moving parts.
In summary, a crankcase is an integral part of an internal combustion engine that encloses and safeguards the crucial rotating and reciprocating elements, while also facilitating the necessary flow and circulation of lubricating oil.
The word "crankcase" is a combination of two words: "crank" and "case".
The word "crank" has Old English origins and was originally spelled as "cranc", which referred to a circular lever or handle used to turn a wheel or shaft. It has Germanic roots and can be traced back to the Proto-Germanic word "krankaz", meaning "sick" or "weak".
The word "case" comes from the Latin word "capsa", which originally meant a box or chest used for containing or enclosing something. Over time, it developed into the general meaning of a container or covering for different objects.
When combined, the term "crankcase" refers to the housing or casing that encloses the crankshaft within an engine. The crankshaft is a component that converts the reciprocating motion of the pistons into rotational motion.
