AI Technical Summary
Technical Problem
Vehicle fires can be accelerated by high oxygen concentrations at the ignition point, and existing carbon dioxide recovery devices do not effectively suppress such fires.
Method used
A vehicle carbon dioxide recovery system with a temperature-swing adsorbent adsorption filter positioned on the fuel pipe, a heater to desorb carbon dioxide, and a controller to manage the system, which releases carbon dioxide to reduce oxygen concentration and suppress fires.
Benefits of technology
The system effectively suppresses vehicle fires by releasing carbon dioxide to lower oxygen concentration, using a temperature-swing adsorbent and controlled heater to decarbonize the adsorbent material and inject carbon dioxide into the fuel leak area.

Abstract
The carbon dioxide recovered by the carbon dioxide capture device is used to suppress vehicle fires. [Solution] The carbon dioxide recovery device 2 of the vehicle 1 comprises an engine 10, a fuel tank 20 in which fuel F is stored, a fuel pipe 30 located below the floor panel 3 and connecting the engine 10 and the fuel tank 20, a cylindrical adsorption filter 40 located on the outer circumference Ro of the fuel pipe 30 and extending along the fuel pipe 30, a heater 60 positioned to heat the adsorption filter 40, and a controller 90 that controls the heater 60. The adsorption filter 40 includes a temperature-swing type adsorbent 44 that adsorbs more carbon dioxide CO2 at lower temperatures than at higher temperatures. The controller 90 desorbs carbon dioxide CO2 from the adsorbent 44 by heating the adsorption filter 40 with the heater 60.
