摘要： PURPOSE:To provide a value close to a measured value by calculating the evaporation of a fuel liquid drop by dividing the liquid drop into three layers, by calculating flame propagation, and then by calculating four items of evaporation, premix combustion, diffusing combustion, and residual carbon combustion of the fuel liquid drop, to determine a total heat generating factor. CONSTITUTION:At the time of simulating combustion, of various fuel measurement values stored in a database, the measurement value of an objective sample, various determined values (the shape of an engine, the timing of fuel blowout, the parameters such as a moisture mixing factor for combustion) of an objective engine, are input into a computer. A fuel liquid drop is divided into three layers of a liquid combustion component/moisture evaporation layer, a moisture evaporation layer, and a fixed carbon surface combustion layer, based on the various determined values of the objective engine and the measurement values of the objective fuel, to calculate the evaporation of the fuel liquid drop. After the flame propagation is calculated, heat generation factors for four items, that is, the evaporation, estimated mix combustion, diffusing combustion, and the residual carbon combustion of the liquid drop are calculated to determine a total heat generation factor, and a net heat generation factor is determined by calculating the formation of NOx, etc.

摘要： PURPOSE:To suppress the rapid increase of the feed of fuel and to prevent lowering of the excessive rate of air owing to the increase thereof by suppressing movement of a fuel connecting lever by means of a hydraulic damper, only when the fuel connecting layer moves in the direction for increasing the fuel supply quantity. CONSTITUTION:When the number of revolutions of a diesel engine is decreased, the decrease thereof is detected by a governor to move a fuel connection lever 3 rightward in a figure. In which case, the piston 7 of a fuel feed amount control device 6 is also displaced rightward in a cylinder 8. In this case, since bypass flow passages 10 and 11 are closed by means of a check valve 12 and a solenoid valve 13, oil in a second oil pressure chamber 8b is prevented from movement through bypass flow passages 10 and 11 to a first oil pressure chamber 8a and a hydraulic damper 9 is normally functioned. Namely, oil in the cylinder 8 is moved from the second oil pressure chamber 8b to the first oil pressure chamber 8a through the microholes 7c of a piston body 7a to suppress movement of the fuel connection lever 3 through viscous resistance. This constitution causes suppression of the rapid increase of the feed of fuel.

摘要： PURPOSE:To reduce variation in feeding quantity of fuel and to improve the efficiency of the fuel by constantly controlling the rotational frequency of a main machine by a governor only when the variation of load is large and usually regulating the fuel to be supplied to the main machine by a signal through an integrating circuit. CONSTITUTION:When the number of rotation of the main machine 1 is sharply changed by load variation due to the influence of a wave or the like and a suddenly changed signal 9 is inputted from a rotational frequency sensor 4 to a differential circuit 7, the circuit 7 converts the input signal 9 into a correction signal 10 to be increased at the time of load variation and outputs the signal 10 to the governor 6. When the rotational frequency of the main machine 1 is moderately changed and a moderately changed signal 11 is inputted from the sensor 4 to the integrating circuit 8, the circuit 8 converts the input signal 11 into an averaged correction signal 12 and outputs the signal 12 to the governor 6. Consequently, variation in the feeding quantity of fuel is reduced during the period of navigation in which load variation is small and the efficiency of the fuel can be improved.
