PURPOSE:To provide an ideal air/fuel ratio by detecting the pressure and temperature of supplied preheated air and by installing a pressure sensor and temperature sensor to an air duct and regulating fuel pressure by the calculation in a calculation circuit based on the detected values. CONSTITUTION:A pressure sensor 5 and temperature sensor 6 that are installed to an air duct 2 convert detected values to electric signals, and those converted electric signals are sent from amplifiers 16 and 17 to converters 18 and 19, and there they are converted from analog signals to digital signals. Then they are inputted to a calculation circuit 9 via an input port 20. In the calculation circuit 9 they are compared with constant and coefficient terms according to a program, and ideal fuel supply pressure for the temperature and pressure are calculated at once, and the calculated ideal fuel supply pressure is outputted as an output via an output port 21 to select a line for an actuator with an air regulating valve 22 that is installed to a pressure equalizing valve actuating pressure pipe 13, and the output signal is converted from digital to analog by a converter 23, amplified by an amplifier 24, and a signal of a level capable of operating an actuator 25. And here for the first time the signal drives the actuator as a control signal to regulate the fuel gas pressure. |
