摘要
The injection system comprises a high-pressure pump (7) having at least one pumping element (18) operated in a reciprocating manner by means of corresponding intake and discharge strokes. Each pumping element (18) is equipped with a corresponding intake valve (25) in communication with an intake line (10), fed by a low-pressure pump (9). An on-off solenoid valve (27) is positioned on the intake line (10) of the pump (7) and is controlled by a control unit (16) with a frequency equal to a whole multiple or submultiple of that of the pumping action, multiplied by a factor ( K ) slightly different from 1.
