Abstract

The aim of the current study was to know the performance and emission behavior of a modified single-cylinder lean-burn SI engine from a stationary diesel engine, runs with gasoline, binary and ternary mixtures of alcohol with gasoline. The tests were looked at 100% throttle open condition, at 10.5:1 compression ratio and fixed RPM of 1500 at different levels of intake charge through manifold injection. The results showed that ethanol-gasoline mixture (10% by volume 10%) was shown an improved performance characteristics compared with methanol-gasoline blend (by volume) and ternary blend of 5% of ethanol—5% methanol—(90%) gasoline blend (by volume) and also a noticeable extension in the lean operation with alcohol-gasoline mixtures. The exhaust emissions, HC and CO were reduced while CO2 and NOx emissions were increased owing to better combustion efficiency and high temperatures in the cylinder. Overall it is accomplished that low concentration of alcohol blending with gasoline enhances performance and reduces emissions under the lean operation of SI engine.
