METHOD AND SYSTEM FOR PURIFYING THE EXHAUST GASES OF A COMBUSTION ENGINE |
摘要 |
A method and system for purifying exhaust gases of a combustion engine or an SCR method for purifying exhaust gases of an internal combustion engine of a vehicle, according to which ammonia gas is exclusively metered in the exhaust gases. The method includes: releasing ammonia gas from at least one solid absorbing matrix where it is stored by sorption; metering the released ammonia gas in the exhaust gases; regenerating the solid absorbing matrix including: generating a refilling ammonia gas by chemically decomposing an ammonia precursor in a biochemical decomposition unit mounted on board the vehicle and storing at least one protein component adapted to decompose the ammonia precursor; directing the refilling ammonia gas to the solid absorbing matrix where it is stored thereon. |
