    • A four stroke combustion engine and method of operation of use and control is disclosed. The engine includes a combustion chamber with an intake manifold coupled to the combustion chamber. A one-way valve is located within the intake manifold. The engine includes an intake valve for modulating the flow of a fuel-air mixture into and out of the combustion chamber. The engine preferably employs a fixed, late closing intake valve. A plenum chamber is located in the intake manifold. The plenum chamber is located downstream of the one-way valve and upstream of the intake valve. During the compression stroke of the engine, a pressurized charge of fuel-air mixture is stored within the manifold and plenum. The amount of the fuel-air mixture stored within the plenum is controlled by adjusting the volume of the plenum, or, alternatively, a plenum valve is used to regulate the amount of fuel-air mixture entering/exiting a fixed volume plenum.

    • To provide a four-cycle combustion engine wherein the air-fuel mixture can be smoothly passed at all times by the utilization of the reciprocating motion of the piston to effectively lubricate the valve operating mechanism and the cranking mechanism and also to allow the air-fuel mixture to be supplied into the combustion chamber with a high suction efficiency, the four-cycle combustion engine includes a valve operating mechanism (30) including a valve drive unit (23) for driving intake and exhaust valves (19, 20) and a drive transmitting unit (29) for transmitting a rotary drive of a crankshaft (8) to the valve drive unit (23), a valve chamber (18) accommodating the valve drive unit (23) and communicated with an intake port (40), an intake passage (33) through which an air-fuel mixture (M) containing a lubricant oil is introduced into the valve chamber (18), a first passage (24) accommodating the drive transmitting unit (29) and connecting between the valve chamber (18) and the crankcase chamber (7), and a second passage (41) connecting between the crankcase chamber (7) and the valve chamber (18). By utilization of the reciprocating motion of the piston (9), a portion of the air-fuel mixture (M) fed from the intake passage (33) is circulated through a circulating passage made up of the valve chamber (18), the first passage (24), the crankcase chamber (7) and the second passage (4).

    • In an engine for a motorcycle, a main shaft is supported rotatably by first and second support walls of a lower case which constitutes a part of a crank case. The center distance between the crank shaft and the main shaft is to be shortened while attaining a reduction in the number of parts and the number of assembling steps. A first bearing hole is formed in a first support wall for fitting therein and holding a first bearing which is mounted on one end of the main shaft. A second bearing hole is formed in a second support wall which permits the main shaft to be inserted therein from an opposite end side of the main shaft until one end of the main shaft is fitted in the first bearing. A second bearing is fitted and held in the second bearing hole so as to be fitted on the main shaft from the opposite end side of the main shaft after fitting of one end of the main shaft into the first bearing.
