ABSTRACT:
There is provided an electronically controlled fuel injection system wherein a constant presetting circuit generates a proportionality constant signal having a frequency corresponding to a proportionality constant, an intake-air amount detecting circuit generates a binary coded signal corresponding to the amount of air drawn into an internal combustion engine, and a multiplier circuit multiplies the proportionality constant signal by this binary coded signal and generates an output signal having a frequency corresponding to the product of the two signals. On the other hand, an engine revolution detecting circuit generates an engine revolution signal having a pulse width inversely proportional to the number of revolutions of the engine, and the number of multiple signals generated from the multiplier circuit during the pulse width of the engine revolution signal is counted to generate a binary coded signal representing the fuel injection quantity required by the engine. A converter circuit generates a pulse signal having a time width corresponding to the binary coded signal representing the required fuel injection quantity and the pulse signal is used to operate fuel injection valves.
