I.C. Engine emission reduction using catalytic converter by replacing the noble catalyst and using copper oxide as the catalyst

Abstract

The toxic gases emitted from diesel engine are more than petrol engine. This system can be used to minimize the harmful gases (NOx,CO,HC) employing tailor-made catalyst instead of traditional catalysts .The main objective is to reduce the level of intensity of toxic gases using alternate catalyst that are economical and effective. There are three sorts of exhaust system 1) reduction catalytic converter 2) oxidization catalytic converter 3) three-way catalytic converter (TWC). A catalytic converter is a gadget that is set on the end of fumes pipe of an automobile. The oxidation catalyst is the second phase of the catalytic converter. It diminishes the hydrocarbons and carbon monoxide by oxidizing them over a platinum and palladium impetus. This catalyst conveys the response of the CO and HC with the rest of the oxygen in the fumes gas. The reduction catalyst is utilized to control NOx outflow and can be utilized as a different framework as a part of expansion to the oxidation exhaust system. The reduction catalyst is fitted at the underlying position of the oxidation framework. We are going to replace the noble catalyst like platinum, palladium and rhodium and add copper oxide as the main catalyst to the ceramic and conduct the testing in the VCR engine at different loads.
