PURIFICATION CAPACITY RECOVERY METHOD OF EXHAUST GAS EMISSION CONTROL SYSTEM |
摘要 |
When a fuel as a reducing agent is supplied to a NOx catalyst on which a NOx or a SOx is reduced, a flow rate of exhaust gas that flows through an exhaust passage is changed, and the fuel is supplied to the exhaust gas flowing through the exhaust passage at a plurality of timings (DeltaT1, DeltaT2) when the exhaust gas flows at different flow rates. ® KIPO & WIPO 2007
