摘要： 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.

摘要： 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).

摘要： A variable valve apparatus of an internal combustion engine includes a first rocker arm that contacts a cam, a low lift cam provided coaxially with the cam, and a second rocker arm capable of contacting the low lift cam. The apparatus also includes a switching mechanism capable of connecting the first rocker arm and the second rocker arm to each other through pins, valves that open by being pressed by the second rocker arms via hydraulic lash adjusters arranged in the second rocker arms, and an oil supply path formed inside the second rocker arms that supplies oil to the hydraulic lash adjusters. A radius of a base circle of the low lift cam is smaller than a radius of a base circle of the cam.
