Abstract

This study investigates the effect of acetone addition to pertalite fuel on exhaust emissions and engine performance in a 150 cc four-stroke Otto engine. Acetone was blended at 1%, 3%, and 5% concentrations and tested using a dynamometer and gas analyzer. Results showed that 3% and 5% acetone mixtures significantly improved engine power and torque, with peak output at 9000 RPM. Emission analysis revealed reduced HC levels and increased CO₂, indicating more complete combustion. However, increased CO at 5% suggests a fuel-rich mixture. The 3% blend was considered the most balanced in enhancing performance while controlling emissions. This study highlights acetone's potential as an efficient and eco-friendly fuel additive.
