PURPOSE:To permit combustion effected by the optimum air-fuel ratio at all times, by a method wherein the title controller is provided with a temperature compensating means, regulating the supplying amount of fuel by a ratio in which the change ratio of the amount of work of a fan with respect to the change of a combustion air temperature is subtracted from the change ratio of the amount of air with respect to the change of the combustion air temperature. CONSTITUTION:A temperature compensating circuit 16 is provided with an air temperature sensor 17, detecting the temperature of combustion air induced into a fan 7, and inputs the control output (voltage signal) of an air-fuel ratio control circuit 15 while the same circuit 16 regulates the output of itself with a predetermined ratio with respect to the change of the combustion air temperature. According to this method, the fluctuation of the amount of air due to the change of the combustion air temperature and the fluctuation of the amount of work of a fan due to the same are compensated whereby combustion may be effected with the optimum air-fuel ratio at all times while the regulation of the output of combustion effected by the compensation of temperature may be coped with the fluctuation of loads in summer and winter, therefore, efficient combustion control may be realized. |
