ABSTRACT:
A combustion control system and method for operating an internal combustion engine to provide the desired air/fuel ratio under all running conditions. The system includes a feedback control which received output from an oxygen sensor coupled to one of the combustion chambers of the engine, the feedback control operating to modify the fuel/air ratio from that achieved by a basic setting that is derived from parameters of engine performance so as to maintain the desired ratio. The system also includes a mechanism for controlling backfire during operation of the feedback control. Backfire corresponding to the cylinder including the sensor is controlled by the system in a manner independent of the feedback control. Backfire corresponding to all other cylinders may be controlled independently of the feedback control or by changing overall feedback control parameters.
