A MULTI-ENGINED SINGLE SCREW POWER PLANT

1,247,379. Power plant. NIPPON KOKAN K.K. Nov.27, 1968 [Dec.5, 1967¦, No.56303/68. Heading F1Q. A multi-engined single screw power plant comprises a first governor 3 for maintaining the speed of a first engine 1 at a desired value, a fuel injection valve 4 whose opening is automatically controlled by the governor so as to supply required amounts of fuel to the first engine 1, a second governor 5 for pre-setting the speed of a second engine 2 at a value which is higher than that set by the first governor and a second injection valve 6 whose opening is set by the second governor when the plant is driven with a torque lower than a prescribed torque but whose opening is set so as to drive the second engine at the same speed as the first engine, whose speed is controlled by the first governor, when the plant is driven with a torque greater than the prescribed torque. The invention can be applied to a more than threeengined single screw plant. 1,247,379. Power plant. NIPPON KOKAN K.K. Nov.27, 1968 [Dec.5, 1967|, No.56303/68. Heading F1Q.
