Embodiment 1
[0025] Example 1: Such as figure 1 As shown, an oil sump structure includes an outer oil sump 1, and an inner oil sump 2 is provided in the outer oil sump 1, so as to form an oil sump between the outer oil sump 1 and the inner oil sump 2. In the oil regulating cavity 11, an oil collector 3 is arranged in the inner oil sump 2 to facilitate preliminary filtering of the oil when the oil pump draws oil from the inner oil sump 2. An upper channel 21 is provided on the upper part of the side wall of the inner oil sump 2, and a lower channel 22 is provided on the lower part of the inner oil sump. The upper channel 21 and the lower channel 22 respectively communicate with the inner cavity of the inner oil sump 2 and the oil adjustment chamber 11. Before the engine is started, the oil in the inner oil pan 2 and the oil 4 in the oil adjustment chamber 11 are in a static state, so the liquid level is the same and higher than the upper channel 21, that is, the upper channel 21 is connected ...

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 seal the crankcase as the outer shell of the oil storage tank to prevent impurities from entering, and to collect and store the lubricating oil flowing back from the friction surfaces of the engine to dissipate some heat and prevent the lubricating oil from oxidizing. When the engine is working, the oil in the oil pan is transported by the oil pump to the friction surface of each moving part of the engine to form a lubricating oil film for lubrication and cooling. The lubricated oil flows back into the oil pan again. In order to ensure the cleanliness of the oil, an oil collector is usually installed in the oil pan. We know that the engine has an optimal working temperature. For this reason, ...
