AUTOMOTIVE EXHAUST AFTERTREATMENT SYSTEM HAVING ONBOARD AMMONIA REACTOR WITH HEATED DOSER

摘要

An automotive exhaust aftertreatment system includes an onboard ammonium carbamate reactor. The onboard ammonium carbamate reactor is coupled to a diesel emission fluid reservoir also included in the system and is configured to generate aqueous ammonium carbamate solution from diesel emission fluid. A doser configured to inject the generated aqueous ammonium carbamate solution has integrated heating.
