Fossil fuel consumption is increasing in a massive amount due to its applications in various sectors. Moreover, use of such fuels creating harmful fumes and gases, which in turn creating an impact on the environment. To reduce the impact on the environment, researchers are continuously trying to research and propose various alternative fuels. In the current study, the Biodiesel was produced from waste soyabean oil and utilized as a fuel in combustion-ignition engine. A four stroke, single cylinder and water-cooled, combustion ignition engine connected is connected with a dynamometer and its performance is checked with prepared Biodiesel. A mixture of waste soyabean oil with pure diesel is mixed with different proportions of blends such as 10%, 20% and 30% to conduct the experiments. Various experiments with different conditions were considered to identify the effect of prepared Biodiesel blends. The experiment results showed that among all blends of Biodiesel, the 20% blend of Biodiesel had given the best results for maximum considered parameters. Such as at highest load of 15 kg, the Brake thermal efficiency obtained maximum as 22.45%, 21.8%, 19.8 and 16.6% for 20%, 10%, pure diesel and 30% blend of Biodiesel. It can be inferred from the experimental investigation suggests that the blended Biodiesel may be considered as an alternate fuel in a four-stroke, single-cylinder diesel engine without any modification in the existing engine. The obtained experimental results may be further utilised to perform the various analysis to enhance engine working conditions.
