摘要： PURPOSE:To enable to prevent overspeed operation of a main engine even at the time when the level of the load applied to the engine is changed from high to low, by stopping the operation of an integrator according to the speed of rotation of the main engine when a high load is applied to the engine. CONSTITUTION:In case of controlling the speed of rotation of a main engine to keep it at a constant value near the maximum engine speed, excessive increase of load causes drop of the engine speed and rise of the output of a speed regulator to a level higher than the maximum fuel injection rate (100%). Under such circumstances that the output of the speed regulator has exceeded 100%, the fuel injection rate is limited to the maximum fuel injection rate by the function of a mechanical stopper of a rack 14. Further, since in this state the engine speed is dropped to a level lower than a rated engine speed, a switch 17 is turned OFF in response to an output signal of an integration stopping mechanism controller 16, so that integration is stopped. On the other hand, since the output maintaining function is kept effective, the level of the output signal of an arithmetic means 11 is kept constant.
摘要翻译：目的：即使在施加到发动机的负载水平从高变低的时刻，也能够防止主发动机的超速运转，通过根据主发动机的转速停止积分器的动作当高负载施加到发动机时。构成：在控制主发动机转速以使发动机最大转速附近保持恒定值的情况下，负载过大会导致发动机转速的下降和速度调节器的输出上升到更高的水平比最大燃油喷射率（100％）。在速度调节器的输出超过100％的情况下，通过机架14的机械止动器的功能将燃料喷射速度限制在最大燃料喷射速度。此外，由于在该状态下发动机转速下降达到低于额定发动机转速的水平时，开关17响应于积分停止机构控制器16的输出信号而断开，从而停止积分。另一方面，由于输出维持功能保持有效，所以算术装置11的输出信号的电平保持恒定。

摘要： PURPOSE:To prevent overrunning by appropriately controlling fuel supply to a main engine when a screw propeller is exposed above the water surface. CONSTITUTION:A signal detected by a detector 17 is supplied to an integrator 14. In the integrator 14, a signal of speed or acceleration of rolling vibration is inputted and converted into vertical displacement of a hull 23, and this displacement signal L is supplied to a function generator 15. Said generator 15 receives the signal L and compares said signal with displacement Lo, at which a screw propeller 21a begins to emerge from the seawater surface, and supplies it as a load control signal to an addition/subtraction instrument 16 forming a speed governor A' of a main engine control system. Said instrument 16 adds together a fuel control signal given from the flucturating difference in rotational speed and a load control signal following the exposure of the screw propeller from the seawater surface 22, and makes this total a control signal of the fuel ejection quantity.

摘要： PURPOSE:To prevent overrotation of a main engine, by a method wherein a signal from a water level detector for detecting relative positions of a ship's hull and the surface of water in proximity to a screw propeller is fed to a function generator, and the supply of a fuel to a main engine is controlled in accordance with a signal from the function generator. CONSTITUTION:The water level detector 14 detecting the relative positions of the ship's hull and the surface of water in proximity to the screw propeller supplies a water level detection signal L to the function generator 15. On receiving the signal L, the function generator 15 compares the signal L with a water level L0 at which the screw propeller starts to appear on the surface of water. When the detection signal L is smaller than the water level L0, that is, when the screw propeller is exposed above the surface of water, a load-controlling signal according to the exposure quantity is supplied from the function generator 15 to an adder-subtractor 16 provided in a governor A' in a controlling system for the main engine. The adder-subtractor 16 adds the load-controlling signal to a fuel-controlling signal fed from a rotating speed controller 8, and feeds a controlling signal for fuel injection quantity to an actuator 9. The actuator 9 receives this controlling signal, and controls a fuel injection pump 5.

摘要： PURPOSE:To enable to prevent overspeed operation of a main engine in a reliable manner even at the time when the level of the load applied to the engine is changed from high to low, by stopping operation of an integrator when a high load is applied to the engine. CONSTITUTION:In case of controlling the speed of rotation of a main engine to keep it at a constant value near the maximum engine speed, the engine speed is lowered when the load becomes maximum, and the output of a speed regulator is raised to a level higher than the maximum fuel injection rate (100%) so as to keep the engine speed at a prescribed value. Under such circumstances, the fuel injection rate is limited to the maximum fuel injection rate by the function of a stopper. Further, in case that the level of a control signal produced from an operational controller 8 is higher than the level of an upper-limit signal produced from a fuel supply rate determining means, operation of an integrator is stopped and the output signal of an arithmetic means 11 is kept at a constant level. Here, since other arithmetic means 10, 12 for executing PID control are kept in operation, load is lowered again and the output of the speed regulator is brought back to the maximum level promptly.
摘要翻译：目的：即使在施加到发动机的负载水平从高变化到低时，也可以以可靠的方式防止主机超速运行，通过在施加高负载时停止积分器的操作引擎。构成：在控制主发动机的转速使其在最大发动机转速附近保持恒定值的情况下，当负载变得最大时，发动机转速降低，调速器的输出升高到高于最大燃料喷射率（100％），以将发动机转速保持在规定值。在这种情况下，通过止动器的功能将燃料喷射速度限制在最大燃料喷射速率。此外，在从操作控制器8产生的控制信号的电平高于从燃料供给速率确定装置产生的上限信号的电平的情况下，积分器的操作停止，并且计算的输出信号装置11保持恒定。这里，由于用于执行PID控制的其他运算装置10,12保持运行，所以再次降低负载，并且速度调节器的输出迅速恢复到最大电平。

摘要： PURPOSE:To improve controllability of rotational frequency in the overall operational area by connecting a function generator individually to a proportional operation unit, integral operation unit and a differential operation unit composing a speed governor. CONSTITUTION:An actuator 09 of a fuel ejection pump is controlled by means of a handle 01 setting the rotational frequency and output deflection 07 of a rotational frequency detector 06. A proportional operation unit 010, integral operation unit 011 and a differential operation unit 012 composing a speed governor are respectively connected to a function generator 1 for the proportional operation unit, function generator 2 for the integral operation unit and a function generator 3 for the differential operation unit. Each of function generators 1-3 decides a proportional constant KP, an integral constant TC and a differential constant TD for the rotational frequency N obtained from a rotational frequency detector 06. Thus, operation of excellent controllability covering the overall rotational frequency area (overall operational area) becomes available.

摘要： PURPOSE:To stop the movement of ship promptly at reversing rotation of engine, through provision of an air release valve and a brake valve which function such that air in cylinder effects negative work to engine during its idling rotation after fuel supply is interrupted and thereby shorten the time required for lowering the revolutional speed of engine to a level capable of injecting brake air. CONSTITUTION:In stopping movement of a ship in motion rapidly, fuel supply to main engine is stopped at first and brake valve 8 is then opened. Thereupon, air is supplied to a starting air control valve 6 through air passage 13, so that valve 6 is operated in relation with the position of starting cam 7. Resultantly, control air is supplied to the top portion of starting cam 5 from the time when piston is located near the top dead point to the time when it is moved to about 120 deg. position after the top dead point, and starting valve 5 is opened for releasing compressed air in cylinder 3 to the atmosphere via release valve 9. This causes rapid drop of the revolutional speed of engine. When the revolutional speed of engine is dropped to a level capable of actuating brake air, cam shaft is shifted to its reversing position and starting air is supplied to cylinder 3 as brake air with valve 9 being closed and starting-air control valve 1 being opened.

摘要： PURPOSE:To set the maximum in-tube pressure at random level by making a slit through small plunger while providing a control groove obliquely in the guide hole of small plunger thereby selecting the start of delivery and the injection freely. CONSTITUTION:A slit 2 of micro clearance beta is made through small plunger 1 having the lower end facing with the inside of plunger chamber 4. A control groove 3 is etched obliquely in the guide hole of small plunger to be fitted with the small plunger 1 and communicated through an oil path 10 with an oil supply chamber 5. A portion of pressurized fuel oil in the plunger chamber 4 is leaked to the oil supply chamber 5 side through utilization of the restricting effect to be determined by the relative position of the slit 2 and the control groove 3. Consequently, the start of delivery and the injection can be selected freely to enable setting of the maximum in-tube pressure at random level.
