Utilizing a closed loop EFI system with an oxygen (Lambda) sensor as a feedback element, techniques are demonstrated to expand the A/F operating range up to 10% from a stoichiometric calibration.Fuel injection timing techniques, such as “simultaneous double fire,” are presented which further enhance the transient engine response of EFI vehicles.A closed loop air control system operating with the EFI system is discussed. This system has resulted in improved idle-speed control during both cold-and warm-engine operating conditions.
