ABSTRACT:
A fuel injection apparatus for internal combustion engines, having a digital control apparatus for producing an actuating electrical signal for the engine injection valves proportional to the engine speed and the quantity of air aspirated by the engine, and a signal correction apparatus for modulating the injection actuating pulse in accordance with other parameters of the engine, such as fuel enrichment during starting or warmup of the engine, adjustment for idle, partial load, and full load conditions, and adjustment for the air-fuel ratio for both short time variable conditions, and long time variations such as variations in barometric pressure. This correction apparatus includes auxiliary storage register, interconnected to numerical frequency converters, which produce the correction signal from the information stored in the auxiliary storage registers.
