CRANKCASE Meaning and
Definition
-
A crankcase refers to the housing or enclosure that contains the crankshaft in an internal combustion engine. It is a core component of an engine, typically made of metal, that serves as a reservoir for lubricating oil. The purpose of the crankcase is to protect and support the crankshaft while also providing a sealed environment for the various engine parts.
Within the crankcase, the crankshaft is mounted and rotates to convert reciprocating motion into rotational motion. It houses the engine's pistons, connecting rods, and main bearings, with the crankshaft extending through the housing. The lubricating oil is stored within the crankcase and is circulated by the oil pump to provide essential lubrication to the moving parts.
The crankcase is designed with various openings and ports to allow for the circulation of oil, the supply of air for combustion, and the expulsion of exhaust gases. Additionally, it often contains a system of baffles and oil filters to ensure proper oil flow and filtration.
In addition to its technical function, the crankcase can also play a role in noise reduction and engine cooling. Some designs incorporate fins or cooling channels to dissipate heat generated by the engine, while others feature noise-dampening materials to minimize vibrations and noise produced during operation.
Overall, the crankcase is a critical component of an internal combustion engine, providing structural support, lubrication, and cooling while housing the crankshaft and other key elements.
Common Misspellings for CRANKCASE
Etymology of CRANKCASE
The word "crankcase" is derived from the combination of two separate terms: "crank" and "case".
1. Crank: It originates from the Old English word "cranc" or "cranca", which means "a bending tool" or "the handle of a winch". Over time, it evolved to refer to the handle used to turn an axle or a rotating device. In the context of an engine, the crank is the rotating shaft that converts reciprocating motion into rotational motion.
2. Case: It comes from the Old French word "casse", which means "box" or "container". Later, it entered Middle English as "cas" with the same meaning. In the context of an engine, a case refers to the housing or enclosure that contains and protects various components.
