    • PURPOSE:To make load sharable on both engines without partiality, by comparing detection signals for the fuel rack position of each fuel injection valve of two engines disposed in parallel, while controlling one of the engines relatively to the other side in accordance with the compared result. CONSTITUTION:With signals outputted from a command device 10 according to the operated variable of a handle 10a, first and second governors 13a and 13b controlling each injection valve of first and second engines E1 and E2 are controlled while fuel rack positions of each injection valve are detected by each of detectors 14a and 14b. Each output signal of these detectors 14a and 14b is inputted into a comparator 15 and then a two-position selector valve 18 is controlled to open or close according to size of each output signal of the comparator 15 via a discriminator circuit 17. Also a three-position selector valve 22 is controlled with the output of the comparator 15 via a selector circuit 19, and when the output of the comparator 15 is below the setting value by way of example, a pressure fluid from a fluid source 23 is fed to a fuel limit device 16 and thereby a fuel injection quantity is reduced to some extent, through which engine speed in the second engine E2 is designed so as to be slowed down.
    • 目的:通过比较并列布置的两台发动机的每个燃油喷射阀的燃油架位置的检测信号,同时根据比较结果控制发动机之间相对于另一侧的发动机,使两台发动机的负荷可共享, 。 构成:根据手柄10a的操作变量从指令装置10输出的信号,控制第一和第二发动机E1和E2的每个喷射阀的控制的第一和第二调节器13a和13b,同时每个喷射阀的燃料箱位置为 由检测器14a和14b中的每一个检测。 这些检测器14a和14b的每个输出信号被输入到比较器15中,然后通过鉴别器电路17根据比较器15的每个输出信号的大小控制两位置选择阀18打开或关闭。另外,三 位置选择阀22通过比较器15的输出通过选择器电路19进行控制,当比较器15的输出低于设定值时,来自流体源23的压力流体被供给到 燃料限制装置16,从而燃料喷射量减少到一定程度,第二发动机E2中的发动机转速通过该速度被设计成减速。
