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.

In a motor control method and apparatus for an internal combustion engine, a point for the beginning of injection moment and injection period for each cylinder are determined in a load-controlled way in a motor controller and supplied to the actuators for execution of the injection. To improve the response characteristic of the internal combustion engine, control information for injection of the cylinder currently to be addressed is transmitted as reserve information for the subsequent cylinder in every transmission cycle. In the event of a load increase, reserve information from the previous transmission cycle is used to control injection in the subsequent cylinder.
