Abstract

The invention concerns a method for noise reduction of an injection diesel engine (M), in particular in transient state. The method consists in: determining a noise index based on a pressure signal (S1-S4) derived from a sensor, said signal providing an instantaneous pressure of the combustion chamber (C1-C4) of the engine (M) during an engine cycle; determining a difference value (Ec) between the noise index (Ib) and a predetermined reference value (Ref); modifying at least one parameter to reduce said difference (Ec) if said difference is greater than a predetermined threshold value. The invention us applicable in particular to diesel engines.
