Abstract
PURPOSE: To prevent an impact by cutting off fuel when a value becomes a specified value, which is found by countering the number of output pulses from the start of deceleration, which is put from an operating circuit to decide the opening period of an injection valve.
CONSTITUTION: The output of NAND circuit 26 is sent to the R terminal of a proceeding-by-ns-counter 27 and the R terminal of a RS flip-flop 28. The output of the proceeding-by-Ns-counter terminal Q is sent to the S terminal of the RS flip-flop 28. The output of an injection pulse operating circuit 16 and the "inv-Q" of the RS flip- flop 28 are fed to the AND gate 29. The proceeding-by-ns-counter 27 counts the number of the output pulses from the injection pulse operating circuit 16 from the point t1 of deceleration. At the point t2 when the countered result comes to a number m, the Q terminal of the proceeding-by-ns-counter 27 reversed from 0 to 1. As the S terminal shows 1 and the R terminal shows 0, the output of the "inv-Q" terminal is converted from 1 to 0. The output pulse of the injection pulse operating circuit 16 is prevented to be sent to an injection valve 6.
