Abstract (en)
[origin: US4770178A] In a method for controlling an injection valve for an internal combustion engine in which the magnet coil of the injection valve is connected to pulsate current by means of a semiconductor switch to an operating voltage in such a way that, during a first time interval, a current which is sufficient to open the injection valve flows and that, following same, there is possibly a second time interval which is dependent on the intended injection time and has a current sufficient for holding the valve open. The first time interval is terminated by disconnection when the current has reached a peak valve which is dependent in accordance with a predetermined function on the operating voltage.
