ELECTRONIC CONTROL FUEL INJECTION SYSTEM FOR SPARK IGNITION INTERNAL COMBUSTION ENGINE Abstract of the Disclosure An electronic control fuel injection system for a spark ignition internal combustion engine is disclosed which controls air flow rate as a function of fuel flow rate by converting an operator's depression of an accelerator pedal to an electric signal, applying the signal to a computer which preferentially determines the fuel flow rate and then the air flow rate, and feedback controlling the air flow rate by using the determined air flow rate and an actual air flow rate sensed by a pressure sensor provided at the upstream and downstream sides of a throttle valve and/or a throttle opening sensor. The computer also receives signals representative of the fuel line pressure and the air pressure in a region adjacent one or more injectors and uses this in adjusting the supply of fuel to the injector(s) to obtain a predetermined constant pressure difference there- across. A unique digital flow control valve may also be used to precisely adjust the air flow rate. The system eliminates auto- mobile "hesitation",while satisfying the requirements of fuel economy and low emissions.
