。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.

車体重量増分招くという問題もある。Conventionally, in the dry sump system, the oil tank is provided separately from the crankcase, and therefore, in motorcycles, three-wheelers, etc., it is necessary to arrange the oil tank in a limited space or to arrange the piping. There is also the problem that these arrangements lead to an increase in vehicle weight.
