Description

Technical Field

[0001] The present application relates to the technical field of engines, and in particular to an oil pan of an engine. Background Art

[0002] The oil pan of the engine is an outer shell that closes the crankcase and serves as an oil storage tank. Its main function is to prevent impurities from entering, collect and store the lubricating oil flowing back from the friction surfaces of the engine, and dissipate some heat to ensure that the temperature of the lubricating oil is not too high. When arranging the oil pan, it is usually necessary to consider how to optimize its heat dissipation performance to ensure the normal working temperature of the lubricating oil. The oil pan is generally exposed outside the vehicle and is one of the main noise sources of the vehicle. Due to space constraints, the engine oil pan needs to be installed at the bottom of the engine. Since the space around the engine is usually very limited, it is necessary to consider how to reasonably use the space when arranging the oil pan to ensure that the oil pan can be installed correctly and work with other parts of the engine.

[0003] The oil suction pan is an oil suction device. When the engine is working, the oil pump sucks oil from the oil pan through the oil suction pan. The existing oil pan and oil suction pan are usually designed separately, but this assembly method is complicated, and there is a risk of failure at each connection point, resulting in many failure points and high maintenance costs.
