Fuel injection installation for IC engine with fuel high pressure pump coupled to fuel injection valve for each engine cylinder, whose engine stroke drives pump piston defining pump work chamber

摘要

The fuel injection valve (12) has at least one first injection valve member (28) for control of first injection port, and a second, slidable injection valve member (128) in hollow first member for control of second injection ports. The second valve member is engaged by pressure of control chamber (54) in closing direction, at least indirectly. The control chamber has a valve (72) controlled connection (70) to pressure section (71), in which is formed delayed pressure rise or reduction during closure or opening of control valve (60). The valve (72) has valve member (76) responsive to respective pressures.
