The working principle of automobile engine oil pan mainly includes two types: wet oil pan and dry oil pan. Through the high-speed operation of the crankshaft, the wet oil pan makes the crank and connecting rod head dip into the lubricating oil each time, and lubricate the crankshaft and bearing shell by splash lubrication. The dry oil pan, on the other hand, uses a separate oil pump system to extract the oil from the external tank, pass through the filter and cooler, and lubricate the engine through the main oil passage
Advantges
Increase engine power : The dry oil pan reduces the rotational resistance of the crankshaft because there is no oil stirring resistance, thus increasing the engine power
increase engine lubrication performance : dry oil pan through high pressure oil pump and multistage parallel return oil pump, to provide higher pressure and more stable oil flow, thereby improving the lubrication effect
reduces stirring resistance : the dry oil pan has no function of storing oil, which reduces the stirring resistance and makes the engine run more smoothly
