A TIMING CONTROL DEVICE OF A INTAKE AND EXHAUST VALVES IN VARIABLE VALVE TIMING ENGINE

摘要

The present invention relates to an intake / vent valve timing adjuster capable of varying the valve opening and closing timing of a car engine of DOHC (Double Over Head Cam) structure by moving force accompanied by the auto-tension Tu idler gear intake / vent valve, to this end, the intake camshaft gear and the linear motion bearing, a linear motion bearing and a rack that is connected between the respective deployed auto tension Tu idler gear to a lower portion of the exhaust camshaft gear disposed / fixed on the lower part of the rack to guide the rack along connections to the rack so that it can be moved horizontally accompanied by the auto-tension you and idler gear means, and a camshaft sensor which is close-up provided on the intake camshaft gear so as to detect the rotation of the intake camshaft gear and is electrically connected to the camshaft sensor detection signal characterized in that the transmitted and, comprising an ECU (60) that controls the operation of the actuator on the basis of the detected signal do.
