Method for limiting maximum injection pressure on injection components, comprises determination of individual valve maintenance currents, marking on valve and entering into injection control system

摘要

An assembly of electrically operated valves (1.1,1.2,1.3, 1.4) which release excess pressure in a fuel injection system are individually calibrated to determine the maintenance currents (33,34,35,36) required at the point of opening. The currents are marked on the valves and the data entered into the memory (44) of a control unit (40) through ports (42). A power unit (41) supplies the currents through ports (43.1,43.2,43.3,43.4)
