摘要:
An ignition and injection system for internal combustion engines is suggested in which a phase sensor which includes a sensor drum driven synchronously with the ignition distributor, particularly a Hall sensor drum formed with a plurality of cut-out portions, one of which is wider than the cut-out portions, and indicates the beginning of an ignition or injection cycle in emergency running. The cut-out portions produce correspondingly long timing pulses, at the beginning of which the ignition coil is charged until the trailing edge occurs and the ignition is effected. The trailing edge of the timing pulses can occur e.g. 10.degree. before the top dead center of the respective cylinder.
