Fuel injection system for internal combustion engine, has high pressure accumulator chamber that branches in supply line, which is continuously connected with pressure intensifier working chamber of pressure transmission unit

摘要

The fuel injection system has a high pressure accumulator chamber (1), a fuel injector with a pressure transmission unit (38), and an injector valve (37). The high pressure accumulator chamber of a high pressure line (21) branches in a supply line (13). The supply line is continuously connected with a pressure intensifier working chamber (17) of the pressure transmission unit as a line (16). A choke valve (4) is rotary arranged by an actuator (2) in its flow rate.
