摘要： In an engine employing a variable lift and working angle control mechanism enabling both a valve lift and a working angle of an intake valve to be continuously simultaneously varied depending on engine operating conditions, the control mechanism includes at least a rocker arm and a control shaft formed integral with an eccentric cam. The valve lift characteristic of the control mechanism varies by changing an angular position of the control shaft. A control-shaft position sensor has a directivity for the sensor output error occurring owing to a change in relative position between the control shaft center and the position sensor. The error becomes a minimum value in a specified direction of relative position change. The specified direction of relative position change is set to be substantially identical to a direction of a line of action of load acting on the center of the control shaft during idling.

摘要： To an internal combustion engine having intake and exhaust valves, there is applied a variable valve timing device. The timing device comprises a first mechanism which varies a working angle of the intake valve within a first given range from a minimum working angle to a maximum working angle; a second mechanism which varies an operation phase of the exhaust valve within a second given range from a most retarded phase to a most advanced phase; and a control unit which controls both the first and second mechanisms in accordance with an operation condition of the engine. The control unit is configured to carry out, when the engine is under an idle operation range, controlling the first mechanism to cause the intake valve to assume the minimum working angle, and controlling the second mechanism to cause the exhaust valve to assume the most advanced phase, and when the intake valve assumes the minimum working angle, controlling the first mechanism to set the open timing of the intake valve to a first point retarded relative to the top dead center (TDC), and when the exhaust valve assumes the most advanced phase, controlling the second mechanism to set the close timing of the exhaust valve to a second point retarded relative to the top dead center (TDC).
