Abstract (en)

A fuel injection system for a diesel engine with a DeNOx catalyst comprises a fuel injection pump arranged to produce periodic pressure pulses and at least one fuel injector connected to the fuel pump by a respective outlet assembly (4) and a supply line. The outlet assembly (4) includes a reverse flow damping valve (6, 8) and an unloading valve (2, 24). Disabling means (18, 22; 30; 32, 34) is arranged selectively to reduce or eliminate the reverse flow damping function of the reverse flow damping valve (6, 8). <IMAGE>
