ABSTRACT:
A control pulse generator for the fuel injection system of internal combustion engines. The rpm-dependent trigger signal is applied simultaneously to two multivibrators one of which generates pulses whose length is determined by engine parameters while the other generates pulses of fixed length. A logical circuit selects the longer of these pulses so that the fuel control pulse will always have at least a minimum length.
