In a piston engine, the crankcase is the housing that surrounds the crankshaft. In most modern engines, the crankcase is integrated into the engine block. Two-stroke engines typically use a crankcase-compression design, resulting in the fuel/air mixture passing through the crankcase before entering the cylinder (s).
Crankcase is the enclosure or housing made for mounting of the crankshaft. It is one of the main components of the engine that creates an enclosure for the vital engine components like crankshaft, connecting rod, bearings, etc. The crankcase is mostly formed by the two different halves.

6 de nov. de 2019 · To construct a crank case of a heavy-duty diesel engine, materials of choice are grey cast (GJL), vermicular (CJL) and ductile irons (GJS). The physical and mechanical characteristics of grey, vermicular and ductile cast irons are tabled for use in various calculations.
29 de mar. de 2013 · The crankcase is the engine’s skeleton – it holds the cylinders, numerous pipes and hoses run through it and innumerable engine components are mounted on it. But it does not only hold the other components, it also has to withstand enormous forces generated by pressures produced by combustion and the movement of the pistons.
For engines under significant loads, the traditional crankshaft material is forged, alloyed steel, including microalloyed grades containing small additions of vanadium, titanium, or niobium, which permit development of superior surface strength, resistance to fatigue, and surface durability in the bearing contacts (Hashimoto et al. 1982).
10 de nov. de 2023 · In essence, the crankcase is a pivotal component of an engine, specifically within the realm of internal combustion engines. Acting as a protective housing, it encloses and safeguards crucial engine components, notably the piston and other internal parts.
