Embodiment 1
[0025] Embodiment 1: as figure 1 As shown, an oil pan structure includes an outer oil pan 1, and an inner oil pan 2 is arranged in a space in the outer oil pan 1, thereby forming an oil pan between the outer oil pan 1 and the inner oil pan 2 The oil regulating chamber 11 and the inner oil pan 2 are provided with an oil filter 3 for preliminary filtering of the oil when the oil pump extracts the oil from the inner oil pan 2 . The upper part of the side wall of the inner oil pan 2 is provided with an upper channel 21, and the lower part of the inner oil pan is provided with a lower channel 22, and the upper channel 21 and the lower channel 22 communicate with the inner cavity of the inner oil pan 2 and the oil regulating chamber 11 respectively. Before the engine starts, the oil in the inner oil pan 2 and the oil 4 in the oil regulating chamber 11 are in a static state, so the liquid level is the same and higher than the upper passage 21, that is to say, the upper passage 21 at ...

The invention discloses an oil pan structure. The oil pan structure comprises an outer oil pan and an inner oil pan. An engine oil strainer is arranged in the inner oil pan. An engine oil adjustment cavity is formed between the outer oil pan and the inner oil pan. An upper channel and a lower channel which enable the inner oil pan to communicate with the engine oil adjustment cavity are formed in the inner oil pan. Before an engine is started, the engine oil liquid surface in the inner oil pan and the engine oil liquid surface in the engine oil adjustment cavity are higher than the upper channel; when the engine is started, the engine oil liquid surfaces are lowered to be flush with the upper channel, and engine oil in the engine oil adjustment cavity enters the inner oil pan directly through the upper channel, so that rapid engine heating is achieved; when the engine work normally, the engine oil liquid surface in the inner oil pan and the engine oil liquid surface in the engine oil adjustment cavity are lowered to be lower than the upper channel, the engine oil in the engine oil adjustment cavity enters the inner oil pan through the lower channel, and thus circulating flowing of the engine oil in the inner oil pan and the engine oil adjustment cavity is formed. The oil pan structure is compact, rapid heating of the engine can be achieved, and the requirement for lubrication during high-speed operation of the engine can be met.
Description
technical field [0001] The invention relates to an automobile engine structure, in particular to an oil pan structure of an automobile engine. Background technique [0002] The oil pan is the lower half of the crankcase, also known as the lower crankcase. The function of the oil pan is to close the crankcase as the shell of the oil storage tank, prevent impurities from entering, collect and store the lubricating oil flowing back from the friction surfaces of the engine, dissipate part of the heat, and prevent the lubricating oil from oxidation. When the engine is working, the oil in the oil pan is delivered to the friction surfaces of the moving parts of the engine by the oil pump to form a lubricating oil film for lubrication and cooling. The lubricated oil then flows back into the oil pan. In order to ensure the cleanliness of the engine oil, an oil filter is usually provided in the oil sump. We know that the engine has an optimal working temperature. Therefore, the car...
