The function of the oil pan is to close the crankcase to prevent impurities from entering, and as the shell of the oil storage tank, collect and store the lubricating oil flowing back from the friction surface of the fuel machine, disperse some heat, and prevent the oxidation of lubricating oil.
Generally made of thin steel plate stamping, some engine oil pan is cast by aluminum alloy (with heat sink). The shape of the oil pan depends on the overall layout of the engine and the capacity of the oil. The oil pan and the cylinder block joint are equipped with a liner or a heat-resistant sealant to prevent oil leakage.
