摘要： A method for controlling a heater of a carburetor and an apparatus therefor. The method includes the steps of: setting a heater pre-heating temperature condition so as for the fuel to be vaporized at the optimum state; setting a heater temperature variation rate properly in accordance with the variation of the intra-room temperature; setting a heater temperature variation rate in relation with the latent heat of the material of the heater; controlling the phase angle of an ac power in accordance with the instructions of a microcomputer; and driving the heater with the variable ac power. Thus a proper vaporizing atmosphere is formed in relation with the variations of the surrounding conditions, thereby contributing to the full combustion of the fuel. The apparatus for controlling the heater is constituted such that a heater temperature sensing section and an intra-room temperature sensing section are connected to the input side of the microcomputer, while the output side of the microcomputer is connected to a phase angle control section.
