PURPOSE:To improve heating effect by means of automatically performing electric conduction and interruption to an air inlet heater when temperature in the engine arrives at the determined value. CONSTITUTION:A spacer 9 having a heater 5 is interposed between a carburetor 1 and an air inlet pipe 2. The heater 5 is integrated by means of arranging exothermic materials 7 in plural stages of ceramic members 6a, 6b and 6c, and further the exothermic materials 7 are controlled by means of a control circuit 12 to receive signals from a temperature sensor 11. Then, it is electrically conducted at less than the determined temperature, and it is stopped together with completion of warming up. |
