Such an oil pan storing oil is called a wet oil pan. At present, the wet oil pan is mostly formed by stamping a thin steel plate, and is shaped like a water ladle, the lowest position in the oil storage tank is provided with an oil absorber and a baffle, the side face of the oil pan is provided with an oil dipstick for checking the oil quantity, and the bottom of the oil pan is provided with an oil drain plug for replacing engine oil.
Under special driving conditions, such as sudden braking or climbing a steep slope of an automobile, and driving in a sudden turning or wave of a yacht, engine oil in the engine oil pan splashes or flows to the other side of the oil suction port due to inertia, which may cause the following two problems: 1. the splash fluctuation of the engine oil easily causes the increase of the air bubble content of the engine oil in the oil pan, thereby causing the conditions of too fast deterioration of the quality of the engine oil and poor lubrication of the surface of the friction pair; 2. the engine is excessively inclined to enable engine oil to flow to the other side of the oil suction port, so that the engine oil is not pumped and oil cannot be pumped, the whole friction pair surface is short-term and free of lubrication, the reliability of the engine is affected, and therefore the maximum inclination angle requirements are met when factories leave factories, and the vehicle performance is limited. In addition, in order to store engine oil, the wet oil pan is deeper, so that the height of an engine is influenced, and the gravity center of the whole vehicle is higher, so that the stability and the safety are influenced.
In the prior art, a baffle is usually arranged in an oil pan, so that the fluctuation of engine oil can be slowed down, oil absorption blank is caused when the engine oil is on a uphill or a downhill, no lubrication phenomenon exists for a short time, and the effect is not ideal. Some special engines also adopt a dry oil pan to be matched with an externally hung oil tank, which relates to the redevelopment of the engine, increases the width of the engine and cannot be installed in original vehicles or yachts. Therefore, there is a need for a new oil pan that is easy to implement and that ensures that oil absorption is not interrupted, reduces the oil gas content, and reduces the oxidative deterioration of the oil under a wider range of operating conditions.
