ABSTRACT:
A fuel injection system for an internal combustion engine utilizing output signals from existing "dual magneto" ignition system to produce output pulses in synchronism with the revolution of the output shaft. A pressure transducer measures the pressure in the intake manifold while a control system generates a VALVE OPEN signal in synchronism with the magneto signal and having a duration proportional to the pressure in the intake manifold to open the fuel injectors and provide fuel to the engine. A special engine starting fuel schedule, hot enrichment schedule, cold enrichment schedule and auto-lean fuel schedule are also generated by the control system.
