Abstract
PURPOSE: To totally solidify a fuel injection system with LSIs and reduce its size, by digitally operating the fuel injection time with a memory which reads out data stored in accordance with the engine revolution and the degree of throttle opening as main parameters.
CONSTITUTION: This fuel injection device is equipped with a clock signal oscillator 1. The engine revolution is computed with the output of a revolution reference position detector 2 as input. The data stored in a memory 5 is read out by using the result of this operation and the output of a throttle opening detector 4 to feed in an interpolative operator 6. The operator 6 computes the fuel injection time from the read-out of the memory 5 and the output of the throttle opening detector 4 to feed in a pulse width converter 7. The converter 7 puts out an injection valve driving signal r having the optimum pulse width from the output of the interpolative operator 6 and the output of the reference position detector 2.
