Abstract (en)
[origin: EP1403510A1] The fuel injection system has symmetric or asymmetric resistive attenuators (71-72, 91-92) and capacitive attenuators (73,93) to attenuate hydraulic waves, particularly waves at a frequency corresponding to the resonant frequency of the injection system. The electronic controller (20) takes account of residual pressure fluctuations at different injectors (10a-10d).
