Patent ID: 8408189

Claim:
A method for managing a gasoline heat engine for a motor, comprising: acting on a first quantity of gas from a recirculation circuit introduced into the supply system, when the motor has an operating parameter reaching a limit threshold at which knocking occurs, wherein the operating parameter is one selected from the group consisting of a quantity of gas from the recirculation circuit introduced into the intake, a quantity of gasoline introduced into a combustion chamber, and an ignition advance, detected at the engine block; and controlling the operating parameter so that a richness of the mixture introduced into the combustion chamber is maintained in a stoichiometric proportion when the operating parameter reaches the limit threshold; wherein the engine comprises: an engine block operatively connected to an intake circuit comprising a compressor; an exhaust system comprising a turbine for driving the compressor; a cooler connected to the intake circuit; and the recirculation circuit operatively connected to both the exhaust system downstream of the turbine and to the intake circuit upstream of the compressor, wherein the cooler is a water cooler, and wherein the water cooler is placed between the compressor and the engine block for cooling a recirculated air-gas mixture output from the compressor.
