The oil pan is the lower half of the crankcase, also known as the lower crankcase. The function is to seal the crankcase as the shell of the oil storage tank, prevent impurities from entering, collect and store the lubricating oil flowing back from the friction surface of the diesel engine, dissipate part of heat and prevent the lubricating oil from oxidation.
Brief introduction of oil pan
The oil pan is located in the lower part of the engine: it can be disassembled, and the crankcase is sealed as the shell of the oil pan. Oil pan is mostly stamped from thin steel plate, and the complicated shape is generally cast iron or aluminum alloy.
An oil stabilizing baffle is installed inside to avoid the impact and splash of the oil surface caused by the bump of the diesel engine, which is beneficial to the precipitation of lubricating oil impurities, and a dipstick is installed on the side to check the oil quantity. In addition, the oil drain plug is installed at the lowest part of the bottom of the oil pan.
