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. |
