ABSTRACT:
A control apparatus retards ignition timing of the engine, and increases an amount of a fuel supplied to the engine based on a retard amount of the ignition timing, by calculating a maximum engine intake air amount at which an exhaust system temperature can be maintained at or below a predetermined upper limit temperature by increasing the amount of the fuel supplied to the engine without causing a misfire of the engine, and limiting an engine intake air amount to a value no greater than the maximum engine intake air amount.
