ABSTRACT:
In an engine exhaust catalyst warm-up control, an ignition timing is delayed than normal first to raise the catalyst temperature, and then a fuel injection amount is dithered to increase and decrease alternately from a normal amount until the catalyst temperature reaches the catalyst activation completion temperature. In place of the ignition delay control, afterburning control may be employed in which fuel cut for a cylinder and fuel increase for the other cylinders are executed. Further, the catalyst warm-up control may be performed by controlling a supercharging operation and an exhaust gas recirculation operation cooperatively.
