Performance and exhaust gas emission of gasoline engine fueled by gasoline, acetone and wet methanol blends

Abstract

Increased motor vehicles have resulted in increased fuel consumption and emissions. Pramium fuel has an octane value of 88. Acetone 110 octane value and wet methanol 113 octane value. Mixing of premium acetone and wet methanol is expected to improve engine performance and reduce emissions. Research using gasoline engines with electronic fuel injection (EFI) systems. The results of the testing, there was a 12.62% increase in brake power. Brake specific fuel consumption (BSFC) has increased by 4.35% compared to P100. The increase in BSFC was due to the calorific value of acetone and wet methanol which was lower than the premium. The resulting CO and HC emissions have decreased. The decrease in CO emissions reached 87.5%. The lowest level of HC produced reaches 46 ppm. Mixing acetone and wet methanol into the premium can improve engine performance. It can be seen from the increase in brake power produced. Exhaust emissions are produced better. CO and HC levels have decreased
