<p><P>PROBLEM TO BE SOLVED: To stably exert high heating and vaporizing capacity, realize prompt rising of temperature and successfully maintain an operating condition of an engine at the time of a large flow rate of fuel and extremely low temperature, in a LPG heating device equipped with PTC heaters. <P>SOLUTION: This LPG heating device is equipped with a heating chamber 30a storing an electric heater 30A in which the plurality of PTC heaters 31a are arranged in parallel, and heats/vaporizes and sends out introduced liquid LPG. In the electric heater 30A, two electrodes/heating plates 31b, 31c having different polarity closely contact with both sides of the PTC heater 31a to form one plate-shaped electrode unit 31A. A plurality of the electrode units 31A are arranged in parallel at predetermined intervals such that the heating faces oppose to each other. The spaces between the electrodes/heating plates 31b, 31c serve as LPG flow passages 32A to heat/vaporize LPG passing through the LPG flow passages 32A. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
