Abstract

PURPOSE: To correctly detect the real fuel injection timing in an injection pipe, by both signals of a crank angle detector and injection timing detecting element.
CONSTITUTION: An injection timing detecting device 7 arithmetically operates a phase difference between the output pulse of a crank angle detector 8 and the output pulse of a piezoelectric elemtn 5, equipped in a fuel injection pipe, to produce the injection timing in each injection pipe as an output signal S. In this method, the actual fuel injection timing in the injection pipe can be correctly detected, then the fuel injection timing can be correctly controlled.
