<p><P>PROBLEM TO BE SOLVED: To improve reliability by simplifying channel structure up to where oil is delivered to an intake port of an engine by an oil pump, in a separation lubricating system of a 2-cycle engine. <P>SOLUTION: In the 2-cycle engine which has a cylinder 11, a crank 16, and crankcases 12 (12a and 12b) housing the crank 16 and holding the cylinder 11 and in which output is taken out of one end side of a crankshaft 13 extending from the crankcases 12 through a power transmission mechanism (7), an oil tank 41 is provided on a side of the crankcase 12b which is simultaneously the other end (rear end side) of the crankshaft 13. The oil tank 41 is arranged to house the rear end side of the crankshaft 13, and in the oil tank 41, the oil pump 50 is provided. The oil delivered from the oil pump 50 passes through oil passages formed in blocks of the crankcases 12 and the cylinder 11 to be delivered to the intake port. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
