ABSTRACT:
To control the ignition timing in a multicylinder engine, the computer output signal which controls the current flow through the ignition coil for generating the spark in the first cylinder is delayed and then applied to the ignition coil controlling the spark in a subsequent cylinder. The computer output signal is delayed by passing through a shift register whose clock input is derived from a pulse generator generating a pulse for each predetermined incremental angular rotation of the crankshaft. If a single ignition coil and a distributor are used, the computer output signal and the delayed computer output signal are applied to an OR gate whose output controls a switch controlling the current through the ignition coil. When more than one ignition coil is used, the computer output signal is applied to a switch controlling the current through the first coil, the delayed computer output signal to a switch controlling the current to a second coil. Further delays may be furnished for a control of sparking in additional cylinders.
