Experimental Analysis of a Single Cylinder Four-Stroke Spark Ignition Engine with Ethanol/Gasoline Blends
Main Article Content
Abstract
Fossil fuels, especially liquid hydrocarbons, which are used in today's transportation system, are running out much more quickly than they are being created. Fuel use is increasing daily, which has an effect on the economy of our nation. Finding new energy sources is the sole goal of fuel research. This study's primary objective is to evaluate the engine's performance and lower fuel consumption in a four-stroke SI engine by using alternative fuel on combustion. A four-stroke spark ignition engine supplied with various gasoline-ethanol mixtures was used for this experiment. Ethanol-gasoline blends, such as E0 (pure gasoline) and E5 (a mixture of gasoline 95% by volume and ethanol 5% by volume), have been used in experiments on break power, specific fuel consumption and break thermal efficiency. These experiments have examined the effects of these blends on these metrics. This study has looked at the use of ethanol-gasoline blends and has thoroughly analysed a number of operating circumstances. Additionally, the outcomes of the experimental testing have been discussed. The performance and emissions of a four-stroke single-cylinder SI (spark ignition) engine with a compression ratio of 5.5 were examined in this study in relation to the impacts of ethanol-gasoline blending. Using ethanol as a SI engine fuel, it has several benefits, including being green, renewable, having a higher-octane rating, being biodegradable and having improved availability and usage in the near future. Ethanol can be produced from cellulose, agricultural biomass, sugarcane, crop residues, municipal waste and other biological sources.
