A new NO x reduction system has been developed which can reduce NO x emissions in diesel engine exhaust using oxygenated hydrocarbons (OHCs) generated from diesel fuel reforming as the primary reductants. The system consists of a sidestream hyperplasma reactor, a diesel fuel reformer and a dual-bed catalytic reactor. A unique feature of this system is a diesel fuel reformer that can produce highly reactive OHCs for NO x reduction. Steady-state performance as well as simulated FTP performance of this system for NO x reduction was evaluated in a sidestream connected to the main exhaust stream of a 4.9L, 6-cylinder Isuzu diesel engine dynamometer system. A dual-bed (BaY + CuY) catalyst yielded a mode-average FTP NO x conversion of 61% when the catalyst volume was 3.6 times the engine displacement. NO x reduction efficiency of the reformed diesel fuel was compared with that of an ethanol-dodecane mixture, E-diesel and NH 3 in laboratory microreactor experiments and engine dynamometer tests. © 2012 Elsevier B.V.
