ABSTRACT:
An electronic system for fuel injection in internal combustion engines of the fuel injection type including a system which modifies the pulse length of the fuel injection control pulses by integration an on-off signal delivered from an air/fuel ratio sensor wherein the integration time constant is varied in accordance with the frequency of the on-off signal from the air/fuel ratio sensor so that the rate of increasing the injection quantity of fuel is increased in accordance with an increase in the engine intake air flow.
