A control system for a variable valve actuating mechanism for an internal combustion engine for varying the lift or timing of intake or exhaust valves in response to engine operating conditions. The control system includes sensors for detecting the pressure in the combustion cylinder and the temperture at the mounting seat of the spark plug. A warning device and fail safe conditions can be activated when an abnormal condition is detected by one of the sensors.

A control system for a variable valve actuating mechanism for an internal combustion engine having a camshaft for actuating intake or exhaust valves, and adjusting means for changing a lift or valve timing of said intake or exhaust valves, comprising: sensor means for detecting a state of combustion

A control system for a variable valve actuating mechanism for an internal combustion engine having a camshaft for actuating intake or exhaust valves, and adjusting means for changing a lift or valve timing of said intake or exhaust valves, comprising: sensor means for detecting a state of combustion in a cylinder of said engine so as to indirectly monitor an operating condition of said variable valve actuating mechanism; a control unit which acts upon said valve actuating mechanism to force it to a certain fail safe condition when any abnormal condition is detected by said sensor means.
