Abstract
The invention relates to a method for injecting fuel, which is at high pressure, into air-compressing internal combustion engines employing an injection system which includes a compressor unit for compressing fuel and containing an actuating device for control valves with which device the nozzle needle of an injector is controlled. One of the two control valves is triggered multiple times or in clocked fashion via a piezoelectric actuator during individual injection phases or during the injection cycle.
