VALVE TIMING CONTROLLING DEVICE

摘要

PURPOSE:To prevent fatigue breakage of component parts such as an advancing plate while reducing a torque shock in changing a valve timing by controlling change of action required for changing a valve timing properly corresponding to an engine load. CONSTITUTION:A valve timing changing mechanism 3 for changing a valve timing of an engine corresponding to an engine rotation number by generating a rotation phase difference between a can sprocket 2 on the crank shaft side and a can shaft 1 is provided. A control unit 31 which receives a signal from an engine load detecting means 33 for detecting an engine load controls an action time required for changing the valve timing for the valve timing changing mechanism 3 to be shorter as the engine load is larger.
