Isopropyl Alcohol, Engine Performance, Alternative Fuels, Experimental Study


Internal combustion engines use alternative fuels to meet the rising need for energy. Alcohol are among the best alternative fuels that can be used in spark-ignition engines without any structural modifications. With their high oxygen content and fast burning rate, alcohols can increase engine efficiency while reducing harmful emissions. The performance of spark-ignition engines was experimentally studied in this study to determine the impacts of employing various isopropyl alcohol ratios. Under full-load conditions and using various engine speeds, the experimental investigation was done. The experimental results showed slight decreases in engine torque with the addition of 10% and 20% isopropyl alcohol. The specific fuel consumption also increased slightly with the addition of alcohol. However, the effective efficiency showed only small decreases with the addition of alcohol. It was found that the percentage changes in the engine performance characteristics were 3.5%, 3.6%, and 2.8%, respectively, for effective efficiency, effective power, specific fuel consumption, and effective efficiency.
