Abstract

A thermal storage device includes a reactor for generating heat by chemically reacting with ammonia; an absorber, provided with an absorbent, for storing ammonia absorbed by the absorbent; and a connection line for connecting the reactor and absorber to each other and moving ammonia between the reactor and absorber. The reactor has a thermal storage member provided so as to cover an outer peripheral portion of the catalyst, a porous sheet provided so as to cover an outer peripheral portion of the thermal storage member, and a casing for enclosing the thermal storage member and porous sheet. One end of the connection line penetrates the casing and opens to the porous sheet.

Claims

exact text as granted — not AI-modified
1 . A thermal storage device for warming up a catalyst arranged in an exhaust system of an internal combustion engine of a vehicle, the thermal storage device comprising:
 a reactor for generating heat by chemically reacting with ammonia;   an absorber, provided with an absorbent, for storing ammonia absorbed by the absorbent; and   a connection line for connecting the reactor and absorber to each other and moving ammonia between the reactor and absorber;   wherein the reactor has a thermal storage member provided so as to cover an outer peripheral portion of the catalyst, a porous sheet provided so as to cover an outer peripheral portion of the thermal storage member, and a casing for enclosing the thermal storage member and porous sheet; and   wherein one end of the connection line penetrates the casing and opens to the porous sheet.   
     
     
         2 . The thermal storage device according to  claim 1 , wherein the reactor further has a heat-insulating member enclosed in the casing and provided so as to cover an outer peripheral portion of the porous sheet. 
     
     
         3 . The thermal storage device according to  claim 2 , wherein the porous sheet is formed from stainless steel or ceramic. 
     
     
         4 . The thermal storage device according to  claim 1 , wherein the porous sheet is formed from stainless steel or ceramic.
