Copper Oxide Coated Diesel Particulate Filters

Automotive emission standards have become stringent worldwide, because of the growing vehicle population and persistent air quality problems. vehicle population increasing rapidly, if all the worlds motor vehicles are lined up bumper to bumper, the line of traffic would circle the globe 120 times, according to world motor vehicle market. Attainment of emission standards will require advance exhaust after treatment systems. Diesel particulate filter (DPF) is recognized as visible solution to reduce the particulate matter emission from diesel engines. This paper mainly focused on the use of CuO coated particulate filters in a single cylinder naturally aspirated four stroke DI Diesel engine. Experimental study was made to find the performance and emission characteristics of the engine. The investigation shows that the DPF was effective for reducing the PM by 60-70%.Further, the investigation shown that there is a moderate increase in power output compared to bare filter and specific fuel consumption also reduces appreciably.
