The present invention relates to a fuel injection timing control apparatus of a dual fuel engine, and more specifically, relates to a fuel injection timing control apparatus of a dual fuel engine, capable of directly supplying hydrocarbon gas in a uniform state at temperature equal to the temperature of exhaust gas generated after performing internal combustion to a catalyst in case that hydrocarbon selective catalytic reduction (SCR) is employed to reduce a nitrogenous compound (Nox), thereby reducing a catalyst purification temperature when a separate hydrocarbon is supplied and preventing a crack from generating in a catalyst carrier. According to the present invention, the fuel injection timing control apparatus (1000) of a dual fuel engine is installed between the dual fuel engine using a mixture of diesel and liquefied petroleum gas (LPG) and a fuel injection pump to allow a driving part and a driven part on both shafts to deliver power. Both ends of an elastic repulsion member (1330) are fixed between the driving part (1310) and the driven part (1320), and a lateness timer (1300) is installed to allow a phase angle of the driving part to be changed toward the driven part (1320) in such a manner that the elastic repulsion member (1330) to be compressed depending on a change of torque of the driving part (1310). The phase angle of the driving part is changed toward the driven part (1320) depending on torque of the driving part (1310) such that the driving part and the driven part are synchronously rotated together with the elastic impulsion member (1330) of the lateness timer (1300). |
