The oil pan is the lower part of the engine, also called the lower crankcase. Its function is to seal the crankcase and prevent impurities from entering, collect and store the lubricating oil returned by the friction surface of the fuel engine, so as to dissipate part of the heat and prevent the oxidation of the lubricating oil. The oil pan is mostly stamped from thin Steel Plate, with an oil-stabilizing baffle installed inside to avoid impact and splash on the right side caused by bumps in the diesel engine. A dipstick is installed on the side to check the oil level. Additionally, the drain plug is installed at the lowest part of the bottom of the oil pan.
Oil pans can be divided into wet and dry types. Splash lubrication is the lubrication of oil in the oil pan through the rotation of the crankshaft and splashing on the friction surface, while pressure lubrication is where the oil pump draws out the oil and sends the oil to the required parts with a certain pressure to achie…
