Alcohols are added to gasoline fuel to improve octane and reduce hydrocarbon pollutants emitted from combustion. Methanol has high octane number and high oxygen content, so it is a suitable type of alcohols to be added to gasoline. Fuel from the addition of methanol to gasoline improves the resultant octane number and enables the blend to work at high compression ratios. In this study, a single-cylinder internal combustion engine was used to measure the effect of adding methanol alcohol in volume fractions of 10% and 20% to gasoline fuel on the noise of the engine. The results showed a significant reduction in the noise of the engine when adding methanol by 10% compared to the other two studied cases.
