    Abstract: A switchable finger follower, including an inner lever and an outer lever. The outer lever is mounted for pivoting movement to the inner lever. A coupling device is located on one of the inner or outer levers and has a coupling pin arranged to move between a locking position, in which the inner and outer levers are connected together for movement in an activation direction, and an unlocked position, in which the inner lever is pivotable relative to the outer lever. A coupling projection is located on the other of the inner or outer lever. The coupling pin engages beneath a coupling surface of the projection in the locking position, and a stop surface of the projection contacts a second stop surface on the one of the inner lever or the outer lever. The second stop surface is located on a removable shim that is replaceable for lash adjustment.

    Abstract: A valve spring device is provided with a first coil spring and a second coil spring combined in series with each other. The inside diameter (coil inside diameter) of the second coil spring is greater than the outside diameter (coil outside diameter) of the first coil spring. A part of the first coil spring including an end portion along an axis is inserted into the second coil spring, thereby forming a combined spring. The end portion of the first coil spring and an end portion of the second coil spring are connected to each other by a connecting member. The first and second coil springs are compressed along the axis as they are located in series between a cylinder head and a retainer. A shaft of a valve is passed within the coil springs.

    Abstract: In a link type variable stroke engine in which a piston, a crankshaft and an eccentric shaft are linked by a linking mechanism, a counterweight part which is provided so that in a projection view on a plane orthogonal to an axis of a rotary shaft, a center of gravity of the counterweight part is located on an opposite side of the axis of the rotary shaft from an axis of the eccentric shaft rotates together with the rotary shaft. Accordingly, it is possible to effectively suppress and lessen half-order inertial exciting force occurring at the eccentric shaft.

    Abstract: A four-cycle internal combustion engine with a valve system having improved durability in the case of high revolution speed. The engine includes a cylinder head having a port, and a valve having a stem part continuous with a fillet part for opening or closing the port. A valve spring including inner and outer springs urges the valve in a direction to close the port. A valve guide holds the stem part slidably. A tubular spring guide supports an outer periphery part of an outer spring to prevent lateral deformation of the spring. A top end of the spring guide is positioned above a top end of a valve guide.

    Abstract: An internal combustion engine incorporating rest cylinders is provided which does not need a high response performance when operating a throttle valve and which can eliminate engine output variations as the number of operable cylinders changes. In the internal combustion engine, some of a plurality of cylinders is configured to rest during normal operation of the engine. The cylinders are divided into a plurality of cylinder groups, and each of the cylinders is provided with an independent throttle valve. An ECU for increasing the number of operative cylinder groups according to at least the throttle handgrip opening is provided. Also provided are motors for bringing the throttle valves in the cylinder in the rest state into a fully closed state on the basis of each cylinder group, a throttle valve position sensor, and the like.
