FUEL CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINES

摘要

A fuel control system for internal combustion engines comprising a control voltage generation circuit for generating a control voltage representative of the operating conditions of an engine, a capacitor-resistor coupled type monostable timer circuit composed of two transistors and having the time constant fixed at a certain value, said control voltage being applied through the resistor to the collector of that one of said transistors which is in the cut-off state when said timer circuit is in its stable state, a current amplifier circuit adapted to amplify for current amplification the output timing pulse from said monostable timer circuit to operate an electromagnetic metering valve, and a trigger signal generating circuit for producing a trigger signal at the fuel metering time of the engine to trigger said monostable timer circuit.
