Experimental investigation on catalytic properties of copper oxide in internal combustion petrol engine during cold start emission

Cold-start emission represents the greatest concentration of emission from today's catalyst equipped vehicle. The existing catalytic converters are successful in reducing emission after engine warm-up. The catalyst is not active during this warm-up period due to its low operating temperature. The vehicle tail pipe emission can be excessive for a period of one to two minutes following the cold-start. One strategy to reduce the quantity of pollutant emitted during the cold start operation is to have the catalyst active at the time of the engine starts. Electrically Heating the Catalyst (EHC) can help to achieve catalyst activity during the cold-start. This paper deals with the potential of catalytic systems with different volume of catalyst and the presentation of thermal analysis provides insight into the catalytic system. In this investigation, an attempt is being made to study the pollution from multi-cylinder SI engine, using EHC with copper oxide as a catalyst. © Totem Publisher, Inc., 4625 Stargazer Dr., Plano.
