    Abstract: An engine valve device, wherein an opening part (7) smaller in area than the end surface of a piston (5) is provided in the end surface of a cylinder (3) to form a valve seat (8), and a valve disc (9) in contact with the valve seat (8) is disposed on the outerside of the valve seat (8) so that the cylinder (3) can be moved away from and toward the valve disc (9) and, in a compression stroke when the piston (5) rises, the valve seat (8) is in press-contact with the fixed valve disc (9) because upward force is applied to the upper end surface of the cylinder (3) and the cylinder (3) is urged toward the valve disc, and the area of the opening part is increasable up to the ultimate diameter of the piston, providing a highly airtight, simple-structured valve device yielding high engine energy efficiency.

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 在用于摩托车的发动机中，主轴由构成曲轴箱的一部分的下壳体的第一和第二支撑壁可旋转地支撑。 在减少零件数量和组装步骤数量的同时，曲柄轴和主轴之间的中心距离将缩短。 第一轴承孔形成在第一支撑壁中，用于装配在其中并保持安装在主轴的一端上的第一轴承。 在第二支撑壁上形成第二轴承孔，该第二支承壁允许主轴从主轴的相对端侧插入其中，直到主轴的一端装配在第一轴承中。 第二轴承装配并保持在第二轴承孔中，以便在将主轴的一端装配到第一轴承中之后，从主轴的相对端侧装配在主轴上。

    Abstract: An engine is disposed with a crankshaft axially oriented in the longitudinal direction of the vehicle body. A camshaft and an exhaust port in a cylinder head are disposed parallel to the crankshaft. The exhaust port is open at the front surface of the cylinder head, and discharges exhaust gases through an exhaust pipe. Hoses extend from a radiator in front of the engine to the front surface of the engine. A valve case is disposed on a left side of a cylinder block in the vicinity of the exhaust port to which the exhaust pipe is connected, and is connected to an air cleaner behind the engine by a substantially straight secondary air pipe.
