VALVE GEAR CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

Title:

VALVE GEAR CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2002/057609

Kind Code:

A1

Abstract:

A valve gear control device of an internal combustion engine controlling the opening and closing operations of exhaust valves (EV1, EV2) and first and second intake valves (IV1, IV2) installed in one cylinder (4), wherein an electromagnetic valve gear mechanism (5) opens and closes the first intake valve (IV1) by an electromagnetic force, a cam type valve gear mechanism (6) opens and closes the second intake valve (IV2) by an inlet cam (11) provided on a camshaft (10) driven in synchronous with the rotation of the internal combustion engine (3) and can produce an cylinder flow motion in the combustion chamber of the cylinder (4), and an ECU (2) controls the operations of the electromagnetic valve gear mechanism (5) and the cam type valve gear mechanism (6), whereby, since the valve opening and closing timings of the intake valve can be optimally set according to the opening conditions, a fuel consumption can be improved, an output can be increased, the accumulation of fuel and the sticking of the intake valve to a valve seat at the intake valve can be eliminated, and a cost and a weight can be reduced.
