ABSTRACT:
A control system for an internal combustion engine for an automotive vehicle determines whether a catalytic converter arranged in the exhaust system of the engine is in a predetermined high temperature condition. When it is determined that the catalytic converter is in the predetermined high temperature condition, priority is given either to a decrease in the amount of intake air supplied to the engine or to an increase in the amount of fuel to be supplied to the engine, depending on operating conditions of the engine.
