HEATING DEVICE FOR LIQUEFIED GAS FUEL SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a heating device for a liquefied gas fuel supply system appropriately vaporizing fuel without excess and shortage.

SOLUTION: The liquefied gas fuel supply system 11 vaporizes liquefied gas and supplies an internal combustion engine 15 with the same. The system 11 is provided with a PTC heater 17 as a heating means heating liquefied gas fuel before vaporization of the same. ECU 41 establishes heating amount of the fuel based on detected fuel vapor pressure characteristics such as detection results of a tank fuel temperature sensor 42 and a tank fuel pressure sensor 43.
