PURPOSE:To simplify construction of an engine, decrease a manufacturing cost of the engine, easily supply lubricating oil of high reliability and reduce a power loss of the engine, by removing an oil pump from the engine. CONSTITUTION:An oil tank 1 is placed in a position higher than an engine 7, and oil flows in a throttle metering portion 4 due to its pressure head and is metered. To reduce temperature depeding quality of the metering, said portion is housed in a thermally insulated box. Further a solenoid valve 2 is open-close operated automatically at operation or stop of the engine. To prevent a pulsating wave of the engine from being applied to a feed oil pipe 5, a pulsating wave preventive device 6 is mounted in the vicinity of an oil feed place to the engine 7. |
