AMMONIA-BURNING INTERNAL COMBUSTION ENGINE

摘要

Inside an engine compartment (53) of a vehicle, an ammonia concentration sensor (50) is arranged above a liquid ammonia injector (13) which is attached to an internal combustion engine body (1) and to the rear in a direction of progression of the vehicle. An ammonia concentration which is detected by the ammonia concentration sensor (50) is used as the basis to judge if ammonia is leaked.
