ABSTRACT:
A system for producing a signal for marking cylinders for control of a phased sequential multipoint injection in an engine including a crankshaft sensor for providing a marking of passings of a top dead center for each of the cylinders and a system for detecting combustion misfires. The system includes the following successive steps. First, injection of fuel for a predetermined reference cylinder is stopped. An occurrence of a combustion misfire for the predetermined reference cylinder is then detected. The moment of stopping of the injection and the moment of detecting the combustion misfire is then compared, and the moment of passing of the intake or firing top dead center for the predetermined reference cylinder is identified. A signal for marking cylinders in phase with the top dead center signal is then produced, initialized at the moment of passing an intake or firing top dead center of the reference cylinder and resuming the sequence of the combustions.
