Handheld type four-cycle engine |
摘要 |
In a handheld type four-cycle engine, the lubricating system includes an oil tank placed outside an engine main body, a through hole providing communication between the oil tank and a crank chamber, an oil feed pipe placed outside the engine main body and providing communication between the crank chamber and a valve operation chamber of a cylinder head, an oil return pipe placed outside the engine main body and providing communication between the valve operation chamber and the oil tank, and a one-way valve for transferring oil from the crank chamber to the valve operation chamber side via the oil feed pipe. The side walls of the engine main body can thus be made thinner and the weight of the engine main body can therefore be reduced regardless of the presence of the oil feed pipe and the oil return pipe. <IMAGE> |
