Where is the crankcase located?
The crankcase is usually located on the bottom of the cylinder block. The crankcase is defined as the area around the crankshaft and crankshaft bearings.
The crankcase is formed by the portion of the cylinder block below the cylinder bores and the stamped or cast metal oil pan that forms the lower enclosure of the engine and also serves as a lubricating oil reservoir, or sump.
The crankcase is the central component in the engine. It houses the entire crank mechanism including pistons, cylinders and connecting rods. Accessories, the transmission/gearbox and the engine control system with cylinder head are attached to the crankcase.
The crankcase is the "body" that holds all of the other engine parts together. It's the largest part of the engine, but must be designed to be both strong and light. To keep the weight low, the brothers used aluminum to make the crankcase. The crankcase was cast at a foundry in Dayton.
Unlike other types of engines, there is no supply of oil to the crankcase, because it handles the fuel/air mixture. Instead, two-stroke oil is mixed with the fuel used by the engine and burned in the combustion chamber.
Definition of crankshaft
1 : a shaft driven by or driving a crank. 2 : a shaft consisting of a series of cranks and crankpins to which the connecting rods of an engine are attached.
The crankshaft is essentially the backbone of the internal combustion engine. The crankshaft is responsible for the proper operation of the engine and converting a linear motion to a rotational motion. Crankshafts should have very high fatigue strength and wear resistance to ensure long service life.
The lower part of the engine block in which the crankshaft runs is called the crankcase. Depending on the engine design, the crankcase also contains the camshaft and the oil pump.
In the vast majority of all cars on the road today, oil is stored in an "oil pan" which is at the bottom of the engine. There's a drain plug there to remove the oil. The drain plug may be located behind a plastic "undertray" or splash shield that may need to be removed.
Oil is stored in a sump, aka the oil pan. The oil pan is attached to the bottom of your engine. Air flowing past the oil pan when your car is in motion allows heat to dissipate.
How does oil get into crankshaft?
The pump sends the oil up to the main bearings of the crankshaft (in the lower middle), which converts linear energy into rotational energy. From there, the oil moves through oil holes drilled in the crankshaft, to the rod bearings, and then through an oil line to the cylinder head (in the upper middle).
A crankcase filter is crucial in ensuring that the oil-contaminated air will not go back into the engine. These days, cars have designs that send the fumes of the crankcase back into the engine. Essentially, the crankcase filter captures the car oil residue in the air passing through the engine.
What is crankcase explosion ? It is an explosion that occurs in the crankcase because of the mixture of oil mist and air in the ratio that is within the range of flammability. In addition there must be a source of high temperature energy sufficient to initiate combustion. This source is called hot spot.
The crankcase filter simply filters the blow by gases to make sure that they are clean before they are rerouted back into the vehicle's intake manifold. Over time, the filter can get dirty and restrict the air flow, and therefore pressure relieving capacity of the system.
An intrinsic component of an internal combustion engine, the crankcase is a drilled metal frame that houses several parts, notably the crankshaft. Its main universal function is to shield the crankshaft and the connecting rods from debris.
