摘要： A reciprocating piston internal combustion engine includes: a sensor system on a gas exchange valve which has a valve head situated at a first end of a valve stem; a lever element which engages at a second end of the valve stem and which is designed to actuate the gas exchange valve by displacing the valve head; a detection element which, upon actuation of the gas exchange valve, is displaced along a displacement path; and a sensor device configured to ascertain a position of the detection element. The sensor device is situated in such a way that the detection element, during a displacement along a portion of the displacement path, moves predominantly in a movement toward the sensor device or away from the same, thereby providing a measurement of valve timing of the gas exchange valve.
