Abstract
An arrangement for injecting fuel for an internal combustion engine has at least one inductive injection valve which is switch controlled via a controllable semiconductor switch. This injection valve is provided with an inductive or capacitive oscillator component for atomizing fuel. During the switching control operation, electrical energy from the inductive injection valve is fed into the oscillator component for exciting its oscillating movement each time the semiconductor switch is opened. On the one hand, with this arrangement no separate high frequency generator is required for the oscillator component while, on the other hand, a second transistor is not required for the switch-controlled output stage with a rapid discharge without loss being possible at least in principle.
