ABSTRACT:
A fuel injection system for an internal combustion engine having intake valves, a plurality of fuel injection valves, and a control unit for determining the fuel injection time and fuel injection duration. The system comprises an ignition pulse generating circuit and computing circuit for producing a fuel injection time delay signal, representing a delay after ignition time, and a circuit for decreasing the time delay with an increase of the engine speed. A maximum time delay is selected to inject fuel after the intake valves of the engine have closed.
