INGCO S-PE-LCC-ET950 Crank Case(S-PE-LCC-ET950)

product details:

A crankcase is a fundamental component in most reciprocating engines, including piston engines found in cars, motorcycles, lawnmowers, generators, and many other machines. Here’s a breakdown of its key functions and construction:

Function:

• Housing: The crankcase serves as the enclosure for the crankshaft, the heart of the engine. It provides structural support for the crankshaft and other rotating parts like connecting rods.
• Lubrication reservoir: The crankcase acts as a reservoir for engine oil. As the engine runs, oil is circulated throughout the crankcase by the oil pump, lubricating various engine components to reduce friction and wear.
• Support for additional components: Depending on the engine design, the crankcase might also house other essential components like the oil filter and sometimes the camshaft.

Construction:

• Material: Crankcases are typically made from robust and lightweight materials like aluminum or cast iron. They need to be strong enough to withstand the forces exerted by the rotating crankshaft and other engine components.
• Parts: A crankcase usually consists of two main sections:
  • Upper crankcase: This is also known as the cylinder block. It houses the cylinders where combustion takes place.
  • Lower crankcase: This is often referred to as the oil pan. It forms the bottom enclosure of the engine and serves as the reservoir for engine oil. The oil pan is usually designed with fins or ridges to aid in oil cooling.
• Openings: The crankcase has various openings to allow for:
  • Crankshaft rotation: Openings allow the crankshaft to rotate within the crankcase. Bearings support the crankshaft at these openings to minimize friction.
  • Oil circulation: Passages within the crankcase and between the upper and lower sections allow for oil circulation throughout the engine.
  • Attachment points: Other engine components like the starter motor or flywheel might be bolted onto the crankcase.
