ABSTRACT:
A number of embodiments of engine control systems wherein fuel injection and spark timing is controlled by individual sensors associated with each of the combustion chambers. This provides more accurate fuel-air control and ignition control, particularly when operating at low speeds when the angular rotational speed of the crankshaft may vary significantly during a single revolution. However, the system includes a fail-safe mode that will provide continued operation in the event an output is not received from one or more sensors. In this event, the timing of the fuel injection and/or ignition is controlled by the output from another sensor. The timing may be done simultaneously from that other sensor output, or in a timed interval after that other sensor output.
