ABSTRACT:
A fuel control system for an electronically controlled fuel injected internal combustion engine, whereby fuel is injected into the cylinders for a fixed number of degrees with respect to the crankshaft rotation. A trigger pulse is fed into a tachometer circuit (32) giving a DC ramp output with respect to speed. A portion of this ramp signal is fed into a monostable circuit (31) whose output pulse duration is now speed dependent and remains constant in degrees of engine crankshaft as the speed of the crankshaft increases. By adjusting the slope of DC ramp output fed into the monostable circuit (31), the fuel "on" time may be set to any fixed number of engine crankshaft degrees desired for a particular engine.
