CENTRAL FUEL INJECTION ENGINE CONTROL SYSTEM

This paper describes the Ford Motor Company's new totally electronic fuel metering concept called Central Fuel Injection (CFI). The CFI concept is a fuel system designed to meet the increasing government mandated emission and fuel economy requirements and, at the same time, remain cost competitive with a carburetor. Ford's introduction of the Electronic Engine Control (EEC) format in 1978 placed an electronic microprocessor and a variety of engine sensors in the vehicle which together are capable of monitoring and controlling such engine functions as spark timing, fuel metering, and Idle Speed Control (ISC). The CFI concept utilizes this format by either speed density calculation or flow measurement of the engine's airflow characteristics and pulse duration modulation of the fuel injection delivery system.
