PURPOSE:To enhance a gasification of the liquid fuel, by means of providing a heat generating element in the air intake pipe located under the carburetor. CONSTITUTION:In an intake air pipe 7 located under a carburetor 1 comprising a fuel nozzle 3 and a throttle valve 6 and the like, is arranged a heating device 11. This device 11 comprises a thermistor 12, being housed in an inner case 15 and outer case 17 and having a positive temperature coefficient, and a pin-shape heat radiating fin 20, protruding into the air intake pipe 7, and the like. With the engine at low temperature, the action of the thermistor 12 increases a heat generated from the fin 20, with the fuel in the air intake pipe 7 rapidly gasified. And when becoming above the constant temperature, reversely the generated heat is rapidly reduced. |
