Abstract (en)

Electronic system for identifying the strokes of a four-stroke internal combustion engine, having an output crankshaft coupled to an angular position sensor which generates a signal having an interval of 360 DEG of the crankshaft. The signal has at least one zero reference corresponding to a zero angular reference of the crankshaft. The system can detect (100) the zero reference and arbitrarily assign (110) the strokes of the engine (2) with respect to the zero reference by determining at least one specified angular relation between the zero reference and the angular position in which the upper dead centre of a first cylinder is reached. The system can monitor (133) the torque generated by the engine to detect a timing displacement of 360 DEG in the arbitrarily assigned strokes and retime (135) these strokes as a result.
