ABSTRACT:
A control system for a multiple cylinder engine includes a vapor fuel introduction system for introducing a vapor fuel vaporized in a fuel tank. A feedback device is used for setting an air fuel ratio feedback compensation value for each of the cylinders or each group of cylinders of the engine and for executing an air fuel ratio feedback control. A fuel supply device is used for supplying engine fuel for each cylinder so as to equalize the air fuel ratio feedback compensation values of each of the cylinders or each group of the cylinders regardless of a change of an operating condition of a vapor fuel introduction control. A desirable A/F feedback control can be accomplished regardless of the execution of the vapor fuel purge in the multiple cylinder engine.
