The exhaust emissions from petrol engines are carbon monoxide (CO) and unburned hydrocarbons (UBHC), and inhaling these fumes is harmful to one's health. They also have an effect on the ecosystem. Aldehydes must be examined if the engine is ran with alcohol. As a result, reducing these contaminants has an immediate impact. Changes in the architecture of the combustion chamber, the fuel mix, and the use of a catalytic converter can all help to reduce emissions. Over the piston crown, a layer of copper with a thickness of 300 microns was applied. inner portion of cylinder liner and cylinder head of two-stroke 2.2 kW petrol engine at rated speed of 3000 rpm with provision of catalytic converter with different catalysts such as sponge iron and manganese ore with air injection, fuelled with gasohol (blend of 20% ethanol and 80% gasoline by volume), with provision of catalytic converter with different catalysts such as sponge iron and manganese ore The impact of characteristics such as catalyst mass, air flow rate, and engine brake mean effective pressure on emissions was investigated. The CO/UBHC in the engine's exhaust was measured using a microprocessor-based analyzer. The wet method was used to measure aldehydes. Catalytic settings were discovered to have a significant impact on the reduction of pollutants in the exhaust. When compared to a conventional engine (CE) with neat gasoline operation, the copper coated spark ignition engine (CCE) with gasohol operation reduced exhaust pollutants significantly.
