ABSTRACT:
Method and apparatus for ignition control of an internal combustion engine provide for computation of an ignition instant based upon operating parameters of the engine measured during a preceding ignition cycle. A device for controlling the ignition of the engine includes a central calculating unit (17) and a peripheral input/output unit (1) controlled by a micro-code program stored in a micro-code ROM (18). Computation of engine speed is accomplished by a disk (5a) having teeth on the periphery (5b), and cooperating with a magnetic detector (5d), the disk being rigid with the crankshaft of the engine to be controlled.
