Abstract

The fuel injection system has a main electronic circuit to produce injector valve opening dwell impulses and an auxiliary circuit to provide additional opening impulses for acceleration pulses. The auxiliary circuit consists of a number of comparators (17, 18, 19) which compare the tension output of a potentiometer with a number of reference signals. The potentiometer is mechanically coupled to the accelerator. The comparators are actuated in succession as the tension output increases so that the produced impulses follows without pause. The comparators are connected to a resistance network in such a way that the tension drops at the collecting point with each comparator.
