USAGE OF RACING IGNITION COIL ON A YMJET-FI 115 CC ENGINE USING ETHANOL-BLENDED FUEL TO REDUCE EXHAUST EMISSIONS

Abstract

This study evaluates the impact of a racing ignition coil on the YMJET-FI 115 CC engine using Ethanol-blended fuel on exhaust emissions. Adding Ethanol to pertalite in compositions of 10%, 20%, 30%, and 40% affects the fuel's chemical properties. Using a standard coil with Ethanol blends (E10, E20, E30, and E40) did not significantly change carbon monoxide (CO) emissions, with the lowest CO level at 4.96% for E30. Conversely, the BRT racing coil with these blends resulted in notable changes, with the lowest CO level at 4.21% for E10. Carbon dioxide (CO2) emissions with the standard coil showed no significant changes, with the lowest CO2 level at 9.7% for E30, whereas the BRT racing coil showed significant changes, with the lowest CO2 level at 7.45% for E40. Hydrocarbon (HC) emissions with the standard coil remained stable, with the lowest HC level at 452 ppm for E30, but the BRT racing coil showed significant changes, with the lowest HC level at 319.5 ppm for E10. The impact of Ethanol blends on exhaust emissions was less significant with the standard coil, while the BRT racing coil showed significant reductions in emissions. This improvement is attributed to more complete combustion resulting from better resistance and voltage. The study concludes that the BRT racing ignition coil effectively reduces exhaust emissions in the YMJET-FI 115 CC engine with Ethanol-blended fuel.
