    • PROBLEM TO BE SOLVED: To simplify the structure and the wiring of a detecting device of generator output, by detecting the load applied to engines, and outputting an instruction to share the load at a specific ratio, to control means, when the load is a specific threshold value or more, as well as outputting an instruction to a fuel injection pump, according to the load. SOLUTION: In the system in which the automatic load sharing devices 1a and 1b of the first and second generators, which are composed of engines 2a and 2b, generators 25a and 25b, and controllers 3a and 3b, are provided in parallel, the engine 2b is started when the load of the generator 25a exceeds a specific value, and a breaker 22b is turned on when the temperature of the engine 2b is made at a specific value or higher. And when the controller 3a detects it, the load sharing ratio to the engine 2b is operated, the fuel injection amount is operated in the controller 3b according to this load sharing ratio, and a fuel injection pump 28b is controlled. And at that time, the fuel feeding by the fuel injection pump 28b is increased and decreased by the signal from a rotation speed sensor 31b.

    • PURPOSE:To substantially improve turning performance of a ship by detecting its turning angle and determining a control quantity so as to selectively adjust a speed of any of a plurality of engines in accordance with a detection result of the turning angle. CONSTITUTION:In the case of a small ship in which driving gears 6, 7, turnably provided about a vertical shaft in an external part of the stern, are interlocking- connected through drive shafts 4, 5 to the first and second engines 2, 3 mounted in a ship body l, turning action is performed by turning each driving gear 6, 7 to right and left through a steering lever or the like by controlling a control handle. Here by mounting an angle sensor 60 for detecting a steering angle alphaof the driving gears 6, 7, a detection signal of the sensor 6c is input to a control circuit 40. In the control circuit 40, a control, such as decreasing an opening of an air control valve in the engine 2 or 3 in a turn inner side in accordance with the detected turn angle, is performed, and turning performance is improved by decreasing propulsion force by the engine in the turn inner side.

    • PURPOSE:To reduce the number of constituent parts as well as to aim at the promotion of low-unit cost of production by connecting a common vacuum generating circuit to each intake manifold of plural engines, in a multitype engine-driven air conditioner which drives plural units of compressors with each of these plural engines. CONSTITUTION:In an air conditioner consisting of a two-train heat pump circuit, making both first and second compressors being driven by a first engine of its constituent element, and another two-train heat pump circuit making both third and fourth compressors being driven by a second engine of its constituent element likewise, each starter of both these engines is controlled by respective speed controllers 107, 117 via two actuator parts 27, 77. In this case, these actuator parts 27, 77 are constituted of a common vacuum generating circuit part M and each vacuum transfer circuit parts N1, N2. Then, the central part of a pipeline R to be connected to each intake manifold of these first and second engines is connected to the common vacuum generating circuit part M inclusive of a vacuum pump 110, and these vacuum transfer circuit parts N1, N2 inclusive of two actuators 102, 112 are connected to an output end of the vacuum generating circuit part M.
