PURPOSE:To accelerate carburetion, by placing inside a suction path of an internal combustion engine a guide cylinder inserted with a PTC ceramic member having a positive resistance temperature characteristic. CONSTITUTION:Suction guide cylinder 5 provided with projected bottom cover 52, which opens in the direction of horizontal suction path 2, is suspended from the bottom of vertical suction pipe 11 having carburetor 1. On the side and the bottom of this guide cylinder 5 is provided PTC ceramic sensor unit 6, whose heat generation sharply increases at a temperature below a certain level. Also, at the bottom of suction path 2 is provided heat riser unit 20, in which cooling water 21 is circulated. By this, the gasification of fuel is enhanced. |
