A control device for an internal combustion engine characterized by: (2) The control device for an internal combustion engine according to claim 1, wherein the valve position detection means for the intake and exhaust valves detects the stroke of the valve stem. (3) The valve position detecting means of the intake and exhaust valves comprises a scale provided on the valve stem and magnetized at predetermined intervals in the axial direction, and a magnetic detection sensor disposed near the scale. A control device for an internal combustion engine according to. (4) A crank angle sensor, a sensor that detects various factors that affect the controlled object, and a storage means that stores the optimal relationship between the various factors mentioned above and the crank angle at which a control signal should be issued to the controlled object. In a control device for an internal combustion engine, the control means receives signals from a crank angle sensor and various factor sensors, and selects an optimal crank angle based on the stored contents of the storage means and issues a control signal. , the storage means stores in advance an operating position of the supply and exhaust valves corresponding to a crank angle that has an optimal relationship with various factors, and a valve position detection means for detecting the operating position of the supply and exhaust valves is provided, If the position detected by the valve position detection means is different from the optimal operating position selected from the storage means based on signals from the various factor sensors, the control means determines that the engine is abnormal. A control device for an internal combustion engine.
