PURPOSE:To enable fuel, which is hardly vaporized, to be used by arranging a heater which allows fuel to be heated and vaporized, a mixing vaporization accelerator which mixes vaporized fuel with air, and an igniter within an air duct of an automobile heating device. CONSTITUTION:An automobile heating equipment includes an ignition burner 4 arranged on the half way of an air duct 1, to which the air is supplied by a blower 2, and a heat exchanger 3. And the ignition burner 4 incorporates a mixing vaporization accelerator 43 in a combustion chamber 41 arranged inside, a heater 48 which heats up and vaporizes fuel such as heavy oil and others from a fuel pump 5, and an igniter 49 which allows vaporized fuel to be ignited and burnt. The mixing vaporization accelerator 43 is made of ceramics which is formed into a honeycomb structure with a heating element 431a embedded in a bulkhead 431. Here, the heating element has a resistance wire with a positive temperature coefficient. And the heater 48 incorporates a heating element 482 inserted into a nozzle 481 which has vaporized fuel outlets 481b and 481c. |
