ABSTRACT:
An electronic fuel injection control method and apparatus employs sensors which sense engine speed and the opening interval of a fuel injection valve to provide a measure of the actual fuel quantity injected thereby. The actual opening interval of the valve is compared to the calculated desired opening interval of the valve to derive a difference value. The supply of fuel to the injection valve is determined by the position of a control sleeve controlled in turn by a command signal-responsive actuator. The difference value is used to adjust the command signal by an amount dependent on the sign and magnitude of the difference value in order to minimize the subsequent difference value.
