Abstract

A hydraulically actuated electronically controlled fuel injection system comprises a pressure intensifier (6, 7) associated with a hydraulically controlled differential valve (4) having a poppet valve (27) opening into a working chamber (10) of the pressure intensifier (6, 7). An external groove (8) is provided on the plunger (7) of the intensifier (6, 7) for connection of the plunger's compression chamber (12) with a nozzle's locking chamber (17) during an injection cut-off period.
