Abstract: A motor drive device for valve timing control of an internal combustion engine includes: a motor drive unit that controls a phase of a camshaft to drive a motor for controlling opening and closing operation of a valve; and a determination unit that determines whether a timing is to start up the motor or to normally drive the motor. The motor drive unit drives the motor with an advance angle when it is determined that the timing is to normally drive the motor by the determination unit, and the motor drive unit normally drives the motor without the advance angle when it is determined that the timing is to start up the motor.

Abstract: A rocker arm includes a pivot portion that is journaled by a rocker arm shaft, a contact portion that projects from the pivot portion to a side of a valve cam, and a pressing portion that projects from the pivot portion to a side of a valve. While including a slipper projecting from the pivot portion in outer side in an axial direction to a side of a camshaft, an overhead valve actuation mechanism for the engine includes a stopper portion with which the slipper comes in contact when the rocker arm swings and reaches a predetermined position at a position opposing the slipper.

Abstract: A partially deactivatable internal combustion engine has two cylinder banks 2R and 2L having cylinders. Some of the cylinders are deactivatable cylinders capable of deactivated by keeping engine valves for them closed and the rest are continuously working cylinders. A camshaft for a cylinder bank having the deactivatable cylinders drives an engine accessory, i.e. a fuel injection pump, whereby variation of camshaft driving torque can be suppressed.

Abstract: A synchronous drive apparatus includes first and a second rotors. The rotors have multiple teeth for engaging sections of an elongate drive structure. A rotary load assembly couples to the second rotor. The elongate drive structure engages about the rotors. The first rotor drives and the second rotor is driven by the elongate drive structure. One of the rotors has a non-circular profile having at least two protruding portions alternating with receding portions. The rotary load assembly presents a periodic fluctuating load torque when driven in rotation. The angular positions of the protruding and receding portions of the non-circular profile relative to the angular position of the second rotor, and the magnitude of the eccentricity of the non-circular profile, are such that the non-circular profile applies to the second rotor an opposing fluctuating corrective torque which reduces or cancels the fluctuating load torque of the rotary load assembly.
