Adaptive Desulfation Control Algorithm |
摘要 |
The exhaust from a diesel-fueled internal combustion engine is treated by a lean NOX trap. The maximum temperature used for desulfating the lean NOX trap is kept relatively lower during early life and progressively increased as the trap ages. Designing for adequate late life performance entails excess capacity during early life. The method utilizes the excess capacity available during early life to slow aging of the trap and thereby extend the trap lifetime. The method facilitates meeting durability requirements for diesel-powered vehicles with exhaust aftertreatment. |
