COMBUSTION CONTROLLER

摘要

PURPOSE:To make possible both fine room temp. control and, air fuel ratio control by a method wherein the air fuel ratio at the unchanged time of the amount of combustion is stored and at the changing time of the amount of combustion an output based on memory contents is sent out. CONSTITUTION:The revolving speed of a fan motor is set at the setting part 18 for the revolving speed of the fan motor in response to a combustion coefficient F determined at a decision part 15 for the amount of combustion and the fan motor 11 is drived. A decision part 22 for the adjusted amount decides the adjusted amount of a pump 7 as an adjusted coefficient B in response to the difference between the temp. of a thermocouple 20 and the set temp. at a detected temp. setting part 21 and a memory part 23 stores this adjusted amount. A computing part 24 computes FXB as the product of the coefficients F and B and a frequency is determined at a setting part 25 for the pump frequency and transmits a signal to a pump drive part 26 driving a fuel pump 7. In response to the signal from the part 15 a switching part 27 switches over a course feeding the coefficient B to the part 24 so that the course passes through the part 22 at the unchanged time of the amount of combustion end through the part 23 at the changing time of the amount of combustion.
