The crankcase is divided into two sections: the upper crankcase and the lower crankcase. The upper crankcase houses the crankshaft and the main bearings, while the lower crankcase houses the oil sump and the oil pump. The crankshaft is supported by the main bearings, which are located in the upper crankcase. The oil sump is a reservoir for the engine oil, and it is located in the lower crankcase. The oil pump draws oil from the oil sump and circulates it through the engine.
The crankcase is a critical component of an engine, and it plays a vital role in the engine's operation. Without a crankcase, the engine would not be able to function properly.
Here are some additional details about the engine crankcase:
* The crankcase is often referred to as the engine block.
* The crankcase is the largest single component of an engine.
* The crankcase is responsible for supporting the crankshaft, which is the main rotating component of the engine.
* The crankcase also serves as a reservoir for the engine oil, which lubricates the moving parts of the engine.
* The crankcase is sealed with gaskets to prevent oil leaks.
* The crankcase is typically made of aluminum or cast iron.
* The crankcase is divided into two sections: the upper crankcase and the lower crankcase.
* The upper crankcase houses the crankshaft and the main bearings, while the lower crankcase houses the oil sump and the oil pump.
