Method for operating injection valve of fuel injection system, involves lowering value of aperture parameter often as the calculated value of opening parameter relative to standardized value of opening parameter is unchanged

摘要

The method involves providing the injection standardized current profile with the injection valves (104,106) so that the level of current parameter of the current profile for the following injection is lowered and a value of aperture parameter is determined according to an effected decrease by the aperture duration of the injection valve. The decrease is so often made, as the calculated value of opening parameter relative to a standardized value of the opening parameter is unchanged. An independent claim is included for arrangement for operating injection valve.
