Abstract

See full text

The production efficiency of ammonia is more raised while avoiding the necessity for a user to supply water for himself/herself in order to produce the ammonia. An exhaust gas purification apparatus comprises a catalyst which purifies an exhaust gas of an internal combustion engine by using ammonia; and an ammonia supplier which supplies the ammonia to the catalyst; wherein the ammonia supplier includes an ammonia producer which produces the ammonia from nitrogen and water; a nitrogen supplier which separates the nitrogen from air and which supplies the nitrogen to the ammonia producer; and a water supplier which separates the water from the exhaust gas of the internal combustion engine and which supplies the water to the ammonia producer.
