Abstract
An electronic fuel injection system generates primary fuel control pulses in synchronism with the crankshaft rotation. The width of these control pulses is adjusted according to the indications of various engine transducers and determines the amount of fuel to be injected. The system also includes an air flow rate transducer whose output signal is monitored by a comparator. When the air flow rate signal undergoes very rapid changes, the comparator triggers a secondary pulse generator which supplies additional fuel injection control pulses to admit more fuel. The occurrence of the secondary pulses is temporally independent of the primary pulses.
