Abstract: PURPOSE: An electronic control type fuel injection pump is provided to allow for ease of setting of maximum fuel limit, while reducing manufacturing procedures. CONSTITUTION: An electronic valve includes an operating shaft(119) having a front end on which a slider having a lower surface having a predetermined tilt angle is mounted. A control sleeve(116) corresponding to the front end of the operating shaft has a slide groove(131) having a tilt angle corresponding to the tilt angle of the lower surface of the slider. The slide groove is open toward the outside of the control sleeve in such a manner that a movement passage(133) for the movement of the operating shaft is formed. The slider of the operating shaft slides by the vertical operation of the operating shaft along the slide groove, to thereby move the control sleeve in an axial direction of a plunger.

Abstract: An exhaust gas processing method according to an embodiment of the present invention includes the steps of detecting a recycling signal to recycle an exhaust filter provided in an exhaust line; injecting urea at a preset normal mode from a urea injector provided in the exhaust line, if the recycling signal is not detected; and injecting the urea at a preset recycling mode, if the recycling signal is detected. If the recycling signal is detected, the urea injector stops injecting the urea. If the quantity of ammonia adsorbed to the inside of a selective catalytic reactor is smaller than a preset value, the recycling mode to recycle the exhaust filter is executed. Therefore, since the urea solution injected from the urea injector is optimized while a particulate filter is recycled, it is possible to minimize the discharge of the ammonia from the selective catalytic reactor.
