Disclosed is a device for reducing the combustion instabilities of a combustion engine, this device including: an intake circuit admitting oxidizing air to the engine, a valve positioned on the engine oxidizing air intake circuit and designed to regulate the flow rate of oxidant gas admitted to the engine, an exhaust gas recirculation circuit connected to the intake circuit upstream of the oxidizing air flow rate regulating valve. The device is arranged in such a way that, at least when an injection of fuel to the engine is cut off, a minimum opening of the valve is assured so as to eliminate recirculated gases from the intake circuit.

Device for reducing the combustion instabilities of a combustion engine

Disclosed is a method for controlling a combustion engine, the combustion engine including an inlet circuit and an exhaust circuit, the method including the steps: determining a temperature of the exhaust gases flowing through the exhaust circuit of the combustion engine; comparing the determined temperature with a maximum threshold; and if the determined temperature is less than the maximum threshold, controlling the engine by decrementing the richness of operation by a predetermined value and jointly incrementing by a predetermined value a level of exhaust gases recirculated between the exhaust circuit and the inlet circuit of the combustion engine.
