PURPOSE:To reduce the weight of the captioned apparatus and markedly facilitate the engine start in a cold region by preheating the intake through the utilization of the exothermic reaction in the case when a metal hydride occludes hydrogen, thus permitting the speedy preheating to a high temperature. CONSTITUTION:A cut-off valve 2 installed into the first passage 1a of an intake feeding pipe 1 is opened, and the adjusting valves 3a and 3b installed into the second passage 1b are closed, and a hydrogen flowing valve 7 is opened to introduce the hydrogen in a hydrogen storage container 6 into an intake preheater 4. Therefore, the metal hydride (MH1) in the container 6 occludes and generates the heat to heat the intake preheater 4. An engine is started by the feed of the preheated intake. If the temperature of the preheater 4 is raised by the discharged heat or a heater after the number of revolution is increased in the stabilized state, the built-in MH1 liberates hydrogen endothermically, and said hydrogen is returned into the storage container 6 through a communicating pipe 5, and the start at the next tie is prepared. Thus, the preheater preheats the intake speedily to a high temperature,and the engine start in a cold region is facilitated markedly. |
