Abstract
A fuel supply system controls the amount of fuel to form a stoichiometric combustible mixture during a normal operating condition of the engine. The mixture is enriched during a transient condition to lower the exhaust gas temperature and to reduce the heat load on the exhaust system. Fuel enrichment is delayed for a delay time which varies depending on the time interval between successive acceleration cycles, to minimize fuel consumption while avoiding overheating of the exhaust system.
