    • A boost assembly (100) for a rotary fuel pump (10) of an internal combustion engine including a turbocharger, the boost assembly (100) comprising a housing (102), a control member (138) which is cooperable with an adjuster of the fuel pump (10) so as to adjust the fuel pump output, a displacement element (110) cooperable with the control member (138), a valve plate (120) engageable with a valve seat (140) so as to define a first position of the control member (138), and limiting means (165,170) arranged to define a second position of the control member (138). The valve plate (120) is movable away from the valve seat (140) in response to air pressure from the turbocharger so as to control whether the diaphragm (110) is exposed to air flow from the turbocharger, thereby to cause the control member (138) to move from the first position to the second position, and the boost assembly (100) includes an adjustment means for adjusting the axial position of the valve seat (140) relative to the housing (102), thereby to adjust the first position of the control member (138).

    • A fuel meter (21) of a fuel injection pump is made movable for fuel metering through a governor lever (14). A swing lever (31) has a power input point (J) which engages with a boost actuator (26). If the boost actuator (26) operates in response to a delayed rise of a supercharged pressure (P), a power output point (K) of the swing lever (31) inhibits the fuel meter (21) from moving for fuel increase. A governor lever (14) is connectably and separably opposed to the fuel meter (21) from a fuel increase side and a start spring (18) urges the fuel meter (21) toward a starting fuel increase side. The swing lever (31) has a pivot axis (Q) displaceable by an actuator (40). When making a cold start, the actuator (40) does not operate to thereby confine the fuel meter (21) to a starting fuel increase position by the power output point (K) positioned on a fuel increase side. When making a warm start, the power output point (K) positioned on a fuel decrease side confines the fuel meter (21) to a starting fuel decrease position (Ls).
    • 燃料喷射泵的燃料计(21)可通过调速杆(14)进行燃料计量。 摆动杆(31)具有与升压致动器(26)接合的动力输入点(J)。 如果升压致动器(26)响应于增压压力(P)的延迟升高而工作,则摆动杆(31)的动力输出点(K)禁止燃料表(21)移动以增加燃料。 调节杆(14)从燃料增加侧可连接地与燃料表(21)相对并且起动弹簧(18)将燃油表(21)向着启动燃料增加侧推动。 摆动杆(31)具有可由致动器(40)移动的枢转轴线(Q)。 当进行冷启动时,致动器(40)不工作,从而通过位于燃料增加侧的动力输出点(K)将燃料计21限制在启动燃料增加位置。 当进行热启动时,位于燃料减少侧的动力输出点(K)将燃料计21限制在起动燃料减少位置(Ls)。
