Abstract
The quantity of fuel injected in a fuel injection system of an internal combustion engine is achieved electronically by generating two series of pulses in synchronism with the engine using one series as a reference for maximum advance and the other series to operate a counter to count down the requisite number of pulses beyond the maximum advance point before the fuel injection is initiated, the count of the counter being varied from a computer in accordance with speed and/or load on the engine.
