Future options for addressing the depletion of fossil fuels and reducing pollution from internal combustion engines may include biofuel as an alternative fuel. This study aims to experimentally and statistically assess the effect of using diesel-biofuel blends on the emissions of a single-cylinder direct-injection engine. Using recycled olive oil, a chemical Tran’s esterification process was used to create biofuel. The experimental results were contrasted with those of a one-dimensional engine model for exhaust emissions and torque, which showed high agreement between test and numerical data. In order to comprehend the factors that affect the engine’s reaction to variations in fuel composition, the thermodynamic characteristics of the engine for various blends were also supplied. According to the investigation, a mixture with 20% of the volume fraction of oleic acid methyl ester olive-based biofuel and 80% of the volume fraction of pure diesel can be an effective fuel alternative for cleaner exhaust emissions while offering almost the same performance.

Biodiesel is regarded as a clean fuel alternative to fossil diesel fuel for fewer pollutant emissions of internal combustion engines. The biodiesel type can be made from waste frying oil, thus it has to be done right. Waste vegetable oil can be provided for free or at a low cost by restaurants and food processors that often use frying oils. Animal fat is also available for free or for a nominal fee from grocery stores, restaurants, and butchers who use lots of fats in their cooking. The methyl ester of oleic acid methyl ester (OAME) biodiesel was produced from used vegetable oil using the transesterification process in order to compare the performance of the 67 kW KUBOTA tractor diesel engine when utilizing OAME and fossil diesel. OAME biofuel was used without being mixed. The engine’s reliability metrics and important indicators, including the brake torque, indicated power, brake-specific fuel consumption (BSFC) and burn duration, were identified. Optimal implementation was met by fossil diesel and the tested characteristics were very close. The OAME biofuel performs better in terms of volumetric efficiency and duration of combustion than the conventional diesel. The decision to choose a specific biofuel that is produced from a particular source so largely hinges on its availability and economic feasibility wherever it is used.

Restaurants and food processors that frequently utilize frying oils can provide waste vegetable oil for free or for a small price. To compare the use of OAME to fossil diesel on the performance of the 67 kW Kubota tractor diesel engine, the methyl ester of oleic acid methyl ester (OAME) biodiesel was created from used vegetable oil using the transesterification process. The OAME gasoline was used straight up. The engine’s performance parameters and key indications, such as the indicated torque, brake torque, indicated power, fuel consumption of the braking force brake (BSFC), and exhaust gas emissions, were determined. The choice of a certain biofuel made from a specific source is primarily based on its economic viability and availability where it is utilized.
