Critical Topics in Exhaust Gas AftertreatmentThe topics most critical to exhaust gas aftertreatment are described in depth: the problems which need to be overcome, and the possible solutions currently under investigation. After treatment is covered as an emissions subject in its own right; and all components of the entire system are included, not just catalysts. Highly technical issues are presented in a way that makes them readily accessible to the non-specialist. It Includes 700 references. |
