Document Type and Number:

WIPO Patent Application WO/2002/064960

Kind Code:

A1

Abstract:

A driver of direct acting valve for internal combustion engine, comprising an intake valve (8) disposed slidably in the vicinity of the intake port (4) of an internal combustion engine (12) and opening/closing the intake port, an electromagnetic actuator (1) for driving the intake valve to be opened/closed, and means (11) for controlling a driving current being supplied to the electromagnetic actuator, characterized in that the current control means feeds the electromagnetic actuator continuously with a driving current of a specified level based on the operating state of the internal combustion engine. The driver of direct acting valve for the internal combustion engine suppresses noise of the internal combustion engine thus realizing a silent internal combustion engine.
