プ３３を備えた注入口３５が開口している。d. Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2, the intake air passage 3 of the gas engine 1 passes through a lubricating oil supply device 5, a mixer 7, an intake port 11 opened in the side wall of the cylinder 9, and enters the inside of the crankcase 13. It is communicated with. The lubricating oil supply device 5 is fixed to the intake port 11 via the mixer 7, and an oil-impregnated body 17 made of a cylindrical porous material with an air hole 15 in the center is provided in the intake air passage 3 passing through the interior. It is held between an annular lid portion 21 and a fitting bullet 19 . Oil chamber 2 provided above the oil-containing body 17
3, a lubricating oil tank 25 provided at a distance communicates with the oil-containing body 17 via a pipe 27 and an oil supply hole 29 opened at the bottom of the oil chamber 23.
Further, inside the lubricating oil tank 25, an end of a pipe 27 is opened below the liquid level, and an inlet 35 having a cap 33 with an intake hole 31 is opened on the upper surface.

れるものである。 In the above configuration, when the gas engine starts, the air sucked into the lubricating oil supply device 5 communicates with the air hole 15 of the oil-containing body 17, and is caused by the negative pressure caused by the flow of the passing air and the suction force of the engine. Then, the lubricating oil contained in the oil-containing body 17 is atomized by suction into the intake air, flows into the crankcase 13, and lubricates the inner surface of the cylinder 9, the bearing portion, etc. Further, the oil in the lubricating oil tank 25 is sucked and supplied into the oil chamber 23 by this suction force.
以上の実施例において、含油体１７から吸入空
気中に混入される潤滑油の量は流入空気の動圧に
比例するので、ガスエンジン１の回転速度に適応
する最適の量の潤滑油を供給できるのである。 In the above embodiment, the amount of lubricating oil mixed into the intake air from the oil-containing body 17 is proportional to the dynamic pressure of the incoming air, so it is possible to supply an optimal amount of lubricating oil that is compatible with the rotational speed of the gas engine 1. It is.
