fuel injection pump

Abstract

Abstract PURPOSE:To simplify the structure and reduce the cost by controlling two fuel feed quantities via an opening/closing means and selectively communicating individual passages. CONSTITUTION:The fuel quantity fed into one of the first pressure chamber 10 and the second pressure chamber 11 through intake passages 17, 42 determines the injection quantity, and its feed quantity is controlled by controlling the opening or closing timing of an opening/closing means 15 during the intake stroke. The fuel quantity fed into the other pressure chamber of the two through fuel passages 45, 43, 44, 13 and a reserve chamber 47 determines the injection timing, and the fuel quantity once guided into the reserve chamber 47 by controlling the closing or opening timing of the opening/closing means 15 fed into the pressure chamber from the reserve chamber 47 during the next intake stroke.
