ABSTRACT:
A method and apparatus for injecting fuel directly into the combustion chambers of an internal combustion engine in which a hydraulic threshold switch is provided which detects the pressure reversal of the pressure course at the end of fuel pumping by a fuel injection pump to a fuel injection valve; upon the attainment of a threshold value of the decreasing pressure, fuel is diverted into a relief chamber to effect a rapid decrease of pressure.
