Abstract
Providing a gas engine in which the drain oil in the blow-by gas as a lubricant is mixed into the air fuel-gas mixture, the lubricant actively lubricating the bearing surfaces of the wear parts such as the valve seats and valve guides as to the intake-air valve and the exhaust gas valve, so that the lubricating device improves the engine lubricating conditions. A lubrication device for a gas engine thereby a valve gear roomis formed on a cylinder head, including: a blow-by gas discharge pipethrough which the blow-by gas flowing into the valve gear roomis discharged; whereby, an oil mist separatoris arranged at the downstream side of the blow-by gas discharge pipe, the oil mist separator separating the drain oil and the air in the blow-by gas; the outlet regarding the drain oil from the oil mist separator communicates with an oil discharge devicethrough an oil pipe, the an oil discharge device being arranged at an upstream side of a gas mixermixing the fuel gas with the intake air for the engine, the upstream being in relation to the intake air; the outlet regarding the air from the oil mist separator communicates with an air inlet of the air cleanerfor the engine intake air, through a breathing pipe
