Abstract
A heat storage device includes a reactor, arranged in an exhaust system, having a formed body chemically reacting with ammonia and generating heat, and an ammonia reservoir, connected to the reactor, for storing ammonia. The ammonia reservoir incorporates therein an absorbent physically absorbing ammonia. The ammonia reservoir has a heat-exchanging structure and is temperature controlled by heat exchange with an external heating medium.
