Reduction of HC/CO emission from si engine by using transition metal oxide catalyst

Abstract

The growing world needs to reduce the automobile cold start emission pollution. Much research work has been carried out in this way, this paper focused on to reduce the automobile cold start emission by using Low mass Electrically heated Catalysts (LMEHC), the Electrically heated Catalyst (EHC) filled with 145 cc volume of chromium oxide catalyst and additional air supply of 80 lpm for a multi cylinder SI engine. It is found that the main converter (MC) could to reach the Light of temperature early when an additional supply of air and the HC and CO emissions are reduced considerably.
