Experimental Investigation of Emission Control from Spark-Ignition Engine Using Electrically Heated Catalyst

This paper deals with the development and performance of the Electrically Heated Catalytic (EHC) converter with copper oxide as a catalyst in a spark-ignition (SI), gasoline-fueled engine. It is found that the EHC reduces cold-start hydrocarbon (HC) and carbon monoxide (CO) emission, when used with existing catalytic converter. From this, the potential of catalytic systems with copper oxide as catalyst is analyzed. Various parameters have been analyzed with the available experimental data, with the help of multiple regression analysis. It is found that the agreement between the analyzed and experimental result is satisfactory. Therefore, it is concluded that, the equation developed in this study can be used with confidence to analyze the emission performance.
