摘要： A variable valve operating mechanism of a four-stroke internal combustion engine includes a slide pin energized by a pin spring in a direction while oil pressure acting on the slide pin in the opposite direction through oil pressure supply passages. The slide pin moves by controlling the oil pressure causing a stem contact surface and a stem through hole to selectively face a valve stem. The mechanism also includes an oil discharge passage including a discharge port which is opened to allow oil acting the slide pin to be discharged when the valve lifter is pressed by a valve operating cam to move for opening the valve. The mechanism is capable of quickly moving the slide pin upon the release of oil pressure when the valve comes into a quiescent state. Therefore, the response of transitioning the variable valve from an operating state to the quiescent state is improved.

A piston includes a pair of mutually opposed longitudinal ribs individually formed with piston pin bosses interconnecting a pair of piston skirt portions on a back side of a piston head. A pair of transverse ribs interconnect the mutually opposed longitudinal ribs with the transverse ribs. The pair of transverse ribs are formed with transverse-rib through holes at places proximal to the back side of the piston head. A skirt opening is formed by cutting away a part of the piston skirt portion that is opposed to the transverse rib and faces the transverse-rib through hole.

摘要： A lubrication structure of an engine arranged so as to reduce the size and weight of an engine. A lubrication structure that utilizes a lead valve and a strainer that are placed close together and divided by a partition, prevents air from being sucked into a strainer at the same time as reducing the amount of air in the engine oil. In this structure the oil is supplied to the oil pan from an oil exhaust port open to a small partition partitioned by a rib. The oil exhaust port communicates with an oil reservoir in a lower part of a crankcase via a lead valve. Oil sent from the oil exhaust port includes air. However, the air is separated by providing the rib. The oil in the oil pan is sucked through the strainer by the oil pump.
