。The lubrication system for the four-cycle engine for tunnels is that an oil reservoir is installed at the bottom of the crack case, and the lubricating oil in the oil compartment is sucked up by an oil pump through an oil strainer.
The so-called wet sump system (Wet su+np system) is used to send the lubricating oil in one oil reservoir to the oil tank, which is then sent to the oil tank, and the 4ν1 lubricating oil in the oil tank is sent to each oil gear. It can be roughly divided into the so-called dry sump system.

ことができる。As mentioned above, in the non-embodiment, the oil tank, which was conventionally separate, is formed integrally with the crankcase 1, and the communication passage 1.0a with the oil reservoir 7 (ltll) is integrated with the case bottom 6 (C Compared to the case where a separate oil tank is installed, the oil tank weight is reduced to 11, and since there is no need for separate piping for the oil tank J2, a large amount of weight can be achieved. In addition, the oil tank I2 is installed using the surplus space under the mission case, which is integrated with the crankcase 1, and the oil tank I2 is installed using the surplus space under the mission case, which is integrated with the crankcase 1. Separate body for communication between oil I?Ff 7 and oil tank 122.
(Since there is no need for Illf, even when the engine 91 is assembled or when it is mounted on the engine, it becomes a very convenient engine, and the center of gravity can be lowered.
