| description | The system includes a detector (50) for measuring fluctuations in pressure in the combustion chamber (51) during the post-combustion period. A circuit (52) is provided for processing the measured signal and developing an electrical control voltage from this signal. A piezoelectric device (53) is arranged in the hydraulic supply line to generate fuel flow pulses at the output of the fuel injectors. The piezoelectric device may be mounted in a chamber of given volume fitted before the injection orifice. Alternatively it may be mounted in a restriction before the orifice, or at the orifice itself. |
