The Second Generation of Electronic Diesel Fuel Injection Systems-Investigation with a Rotary Pump 860145

This paper describes concepts of the next generation of electronic diesel fuel injection (EDFI) systems, and the test results of the prototype, named “Mode 1-1”.
Important characteristics of the next generation of EDFI will be; mechanical simplicity, direct control and pump intelligence,.
Direct spill control using a high speed solenoid valve for injection regulation and pump mounted electronic circuits were used in the “Model-1” system.
The test results demonstrate the advantages of this system, and suggest possibilities of new functions such as individual cylinder control, pilot injection and multi fuel usage.
