PURPOSE:To accelerate starting-up of warming by providing a heater which uses metal hydride and feeding hydrogen on engine start and carrying-out heating with engine cooling water and releasing and recovering hydrogen during normal driving. CONSTITUTION:When an engine is started, hydrogen gas is introduced into a heater 1 from a hydrogen storage cylinder 6 through a hydrogen communication pipe 5 by opening a hydrogen flowing valve 4. Hydrogen is occluded onto the metal hydride filled in the heater 1, and heat is generated, and warming air is heated by said heat. When the engine temp. rises, and normal driving is realized, engine cooling water is introduced into the heater 1, and the metal hydride is heated to release the occluded hydrogen, and said hydrogen is recovered into the hydrogen storage cylinder 6 and stored. Therefore, starting-up of warming on engine start can be accelerated. |
