摘要： PROBLEM TO BE SOLVED: To improve the vaporizing performance of a heater and prevent unburnt gas (HC) from discharging in an internal combustion engine equipped with a heater to promote the vaporization of fuel. SOLUTION: A cross sectional shape of a passage arranged in the heater is made flat to prevent the air stream from spreading from the heater. Since air can be concentrated into the heater, and air can be uniformly fed onto a heater surface, fuel can be promoted to evaporate on the heater surface. Thereby, the combustibility in the internal combustion engine can be improved at the time of the starting and immediately after the starting so as to reduce the discharge of the unburnt gas (HC).
