Document Type and Number:
Japanese Patent JP6357234
Kind Code:
B2
Abstract:
The present invention is a method for removing pollution from exhaust gas circulating in an exhaust line (12) of an internal-combustion engine. The exhaust line comprises an ammonia-sensitive catalyst (46) with selective NOx catalytic reduction traversed by the gas and an injector (56, 58) for injecting a reductant of the pollutants The catalyst decomposes the reductant into a hydrogen gas phase and an ammonia gas phase and, for a gas temperature below approximately 150° C. injects the hydrogen into the exhaust line in combination with a hydrogen-sensitive NOx catalyst.
