INTERNAL COMBUSTION ENGINE VALVE CONTROL APPARATUS

Title:

INTERNAL COMBUSTION ENGINE VALVE CONTROL APPARATUS

Document Type and Number:

WIPO Patent Application WO/2003/010420

Kind Code:

A1

Abstract:

An internal combustion engine valve control apparatus capable of suppressing increase of the inertia mass of an engine valve and appropriately setting the valve closing timing according to the operation state, thereby improving the specific fuel consumption and increasing the rotation speed and output as well as reducing the cost and weight. The valve control apparatus controls opening&sol closing of the engine valve. A cam type valve train opens&sol closes the engine valve by a cam driven in synchronization with the rotation of the internal combustion engine. An actuator engages with the engine valve which has opened and holds the engine valve in its open state. An ECU controls operation of the actuator, thereby controlling the engine valve closing timing.
