Abstract: A valve train for an internal combustion engine that uses motors to open/close intake valves of cylinders. The motors drive the intake valves for each of a plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals. Since the intake valves are driven for each of the plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals, the explosion stroke is performed regularly even when an operation is conducted with only a particular group of cylinders. This makes it possible to inhibit driveability deterioration.

Abstract: The present invention provides a variable valve mechanism control device that is capable of reducing the power consumption and rating of an electric motor by allowing camshaft rotary inertia torque to reduce spring reaction force during a valve lift. Camshaft rotary inertia force is increased to a value not smaller than a predetermined value before the start of a valve lift. During the time interval between the instant at which the valve lift starts and the instant at which the maximum lift is provided, the spring reaction force of a valve spring is used as deceleration torque for the camshaft rotary inertia force. During the time interval between the instant at which the maximum lift is provided and the instant at which the valve lift terminates, the spring reaction force is used as acceleration torque for the camshaft rotary inertia force. The camshaft rotary inertia force cancels the spring reaction force so that motor torque generated during a valve lift is composed of counter-friction torque only.

Abstract: During a fuel cut, a recommended reactivated cylinder and a reactivatable cylinder are determined based on the stopped positions of an intake valve and an exhaust valve (step 104). A fastest reactivatable cylinder is then determined based on the crank angle, from among the recommended reactivated cylinder and the reactivatable cylinder (step 108). Also, the rotating direction of a motor when a variable valve drive apparatus starts to be driven again when the fastest reactivatable cylinder is made the reactivated cylinder is also determined. When a reactivation command is output, operation resumes from the fastest reactivatable cylinder when the situation calls for rapid reactivation (step 124). When the situation does not call for rapid reactivation, operation resumes from the recommended reactivated cylinder (step 118).
