The principal pollutants produced by spark ignition engines are carbon monoxide (CO) and unburned hydrocarbons (UHC). These pollutants need to be stopped right now since they are harmful and affect people's health. Copper with a thickness of 300 microns has been applied to the cylinder head's interior and piston crown of the spark ignition engine. For reducing emissions when operated with gasoline, a variable compression ratio, copper-coated spark ignition engine with a catalytic converter using sponge iron catalyst has been studied (blend of 20 percent ethanol and 80 percent gasoline by volume). On these emissions, the impact of many factors is examined, including void ratio, airflow rate, injected air temperature, speed, compression ratio, and engine load. A microprocessor-based analyzer is used to measure the amount of CO/UHC in the engine's exhaust. Speed, load, compression ratio, and air injection into the catalytic converter are all found to have a significant impact on the amount of pollutants in the exhaust. A copper-coated spark ignition engine operating on gasoline alcohol considerably reduced exhaust emissions as compared to a typical engine operating on pure gasoline.
