Abstract

PURPOSE:To prevent overheat of lubricating oil by a method wherein lubricating oil is fed with a pressure only to the lubrication-needing part of an engine through a feed piping, the size of an oil pump is reduced, and after lubricating oil after lubrication is cooled in a lubricating oil tank, it is returned to an oil pan. CONSTITUTION:Lubricating oil 17 in an oil pan 12 is fed to a lubrication-needing part 18 of an engine through a piping 31 with the aid of an oil pump 16. After the lubricating oil 17 by which the lubrication-needing part 18 of an engine is lubricated is fed to an exhaust turbosupercharger 15, it is introduced to a lubricating oil tank 14 through a return piping 32. In this case, after the lubricating oil is stored by a partition wall in the lubricating oil tank 14 once for natural cooling, it is returned through a given discharge port to the oil pan 12 by means of a passage. As noted above, the lubricating oil 17 is fed only to the lubrication-needing part 18 of an engine through a feed piping 31, and reduction of the size of the oil pump 16 is achieved. The lubricating oil 17 is cooled in the lubricating oil tank 14 to return it to the oil pan 12 to prevent overheat of the lubricating oil 17.

Next, the effect will be explained. In the semi-dry sump type lubrication system described above, as shown in FIG. 4, the lubricating oil 17 that is pumped by the oil pump 16 is supplied to the lubricating parts 18 of the engine through the feed pipe 31. Therefore, a portion of the lubricating oil 17 is transferred to the lubricating oil tank 14 through a pipe 50 branched from the feed pipe 31 as in the conventional case.
There is no need to send the oil to the oil pump 16, and the capacity of the oil pump 16 only needs to be a discharge amount corresponding to the amount supplied to the lubricating parts 18 of the engine, making the oil pump 16 smaller than before.

The lubricating oil 17 after lubricating the engine lubricating parts 18 is sent to the exhaust turbo supercharger 15, and after lubricating the exhaust turbo supercharger 15, it flows into the all lubricating oil tank 14 from the return pipe 32. High temperature lubricating oil 17 that has flowed into lubricating oil tank 14
flows into the lubricating oil tank 14 from the population 35 in FIG.
The lubricating oil is temporarily stored in the lubricating oil tank 14 so that it does not flow out immediately from the discharge port 36 through the partition wall 34, and is allowed to cool naturally during that time before passing through the discharge port 36 and the passage 37 to the crank chamber 38.
Return to Therefore, compared to the conventional case where the high-temperature lubricating oil 17 is directly returned to the oil pan 12 after lubricating the exhaust turbo supercharger 15 through the piping 51 in FIG. It does not flow into the pan 12, and overheating of the lubricating oil 17 is prevented.
