Abstract: A valve operating device for an internal combustion engine having a drive rocker arm operatively associated with an intake or exhaust valve and a free rocker arm releasable from the intake or exhaust valve. The drive rocker arm and the free rocker arm are disposed adjacent to each other and operable selectively in mutually different modes according to the rotation of the camshaft. In one embodiment either the drive or free rocker arm has two arms connected together with one arm on each side of the other rocker arm for balanced loading. A selective coupling mechanism is disposed between the drive rocker arm and the free rocker arm for selectively connecting and disconnecting them with a coupling pin movable in a direction substantially normal to the axis of the rocker shaft.

Abstract: A power unit mounting structure in a motor vehicle includes a power unit comprising an engine having a crankshaft, a transmission coupled to the crankshaft of the engine, and a differential interposed between drive axles connected to a pair of laterally spaced front road wheels of the motor vehicle and the transmission. The power unit is mounted in a front portion of the motor vehicle with its center of gravity positioned rearwardly of the drive axles extending from the differential toward front road wheels serving as the drive road wheels. A steering gearbox extends parallel to the drive axles and is disposed forwardly of the drive axles.

Abstract: A valve operating mechanism for an internal combustion engine having a valve disposed in an intake port or an exhaust port of a combustion chamber and being openable by a rotatable cam and cam follower in synchronism with the engine crankshaft rotation. The valve is normally urged toward the closed position by a spring means encircling the valve. Various embodiments are disclosed for varying the resilient force urging the valve toward the closed position during different engine operating conditions, such as, increasing the resilient valve closing force during high-speed operation for ensuring proper valve operation and decreasing the resilient valve closing force during low-speed operation for reducing friction in the valve operating mechanism. The valve operating mechanism includes means for switching between actuation by a low-speed cam or a high-speed cam. One form of the spring means includes a mechanism for increasing the spring force on the high-speed cam follower only during high-speed operation. Another form of the spring means includes a valve spring having a non-uniform rate of compression for imposing a higher rate of increase of spring force as the valve is opened a larger amount at high-speed.

Abstract: Valve operating apparatus is disclosed in which the valves are operated by transmitting members in the form of rocker arms or bucket lifters driven by cams having different cam profiles and coupling devices for selectively connecting or disconnecting adjacent transmitting members to vary the operation of the valves under different engine operating conditions. The transmitting member that is not directly associated with a valve and that idles when not coupled to an adjacent transmitting member is spring biased toward the operating cam by an abutment member and means are provided to limit the stroke of the abutment member.

Abstract: A valve operating mechanism for an internal combustion engine having cams rotatable in synchronism with a crankshaft, a pair of valves disposed in intake or exhaust ports of a combustion chamber, and four pivotable rocker arms for transmitting the lifting motion of said cams to said valves. Four cams are provided with different cam profiles corresponding to respective ranges of rotational speeds of the engine. Switching means are operated by hydraulic oil pressure for selectively connecting and disconnecting the rocker arms to thereby operate the valves in several different modes for different engine speeds.

Abstract: Apparatus for controlling the operation of intake or exhaust valves of an internal combustion engine in which cam-driven rocker arms that operate the valves are selectively connected or disconnected for movement in unision or for independent movement in order to open and close the valves in accordance with the various modes of engine operation. Control of the valves is produced by the cooperative effect of hydraulic pressure and variable spring forces whereby more accurate valve operation over a greater number of engine operating modes is achieved.

Abstract: A light, compact angle-of-rotation sensor is comprised of a magnetic ring within which resin is used to fix the ring to the periphery of a shaft. Formed on the magnetic ring are insets into which the resin enters, providing a strong bond between the resin and the magnetic ring. In addition, a key inset into the shaft provides a strong bond between the resin and the shaft. Magnetized zones are formed on the outer surface of the magnetic ring, and magneto electric transducer means are arranged in the proximity of these zones to face said zones, and the angle of rotation is detected from the changes in magnetism that accompany the rotation.

Abstract: A method of manufacturing an angle-of-rotation sensor comprises fabricating a rotating member by providing a shaft coaxially inside a magnetic ring made of ferrite magnetic material or the like, and filling the space between shaft and ring with resin. As the resin is first provided on the outer surface of the magnetic ring, then in the interior, a balance is achieved between tensile stress from within the ring and compressive stress from the outside of the ring, and as a result the ring is not broken or cracked. Thus, with this method it is possible to make the angle-of-rotation sensor small and light.
