Effect of MnFe2O4 Nanoparticles to Reduce CO and HC Levels on Vehicle Exhaust Gas Emissions

Abstract

The air pollution particle emitted from transportation in Indonesia Bay 2015 consist of 70.50% CO; 18.34%HC; 8.89% NOx; 0.88% SOx; 1.33%. These gases are very harmful to humans. To reduce the toxic gaseffect, special treatment is needed, one of them is by applying catalyst on exhaust system. MnFe2O4 has thepotential to bind the CO and HC elements contained in the exhaust gas. This study aims to investigate theeffect of MnFe2O4 addition on catalityc converter towards CO gas and HC emissions of motor vehicles.Therefore, the percentage of exhaust reduction with and without applying MnFe2O4 on varied enginerotation using fuel with RON of 88, 90, 92 and 98 can be revealed. The results describe that the highestreduction precentage of CO content by applying MnFe2O4 nanoparticles as a catalyst for premium, pertaliteand pertamax fuel are 34.1% (effective at low and high rotation); 31.1% (effective at all rotations); and3.9% (effective at low rotation). On the other hand, the highest reduction percentage of HC content onpremium, pertalite, pertamax and pertamax turbo fuel are 79.3% (effective in high rotation); 71.4%(effective at high rotation); 53,6% (effective in high rotation); and 2.1% (only effective at low rotation)
