Abstract
In this study, biodiesel is produced from waste sunflower oil and its ef-fect on engine performance and specific fuel consumption is experimen-tally investigated. Transesterification method was used in biodiesel pro-duction of waste sunflower oil. After production, analyzes giving charac-teristics of biodiesel such as density, kinematic viscosity, sulfur and water content were made. As a result of the analysis, the biodiesel fuel with a viscosity of 4,372 mm2/s, which has a reaction temperature of 60°C, an alcohol content of 25% and a catalyst ratio of 0.05%, was cho-sen as a reference fuel, as it was observed to comply with European Standards of EN 14214. Standard diesel fuel was taken as reference for the purpose of examining the effect of biodiesel on engine performance. Performance and fuel consumption tests of the produced biodiesel and standard diesel fuel were carried out at the full load position at seven dif-ferent engine speed levels. Experiments were carried out on a single cy-linder four-stroke Cussons P8160 engine. As a result of the test, it was observed that there was a 7.06% reduction in engine moment compared to the standard diesel fuel use of B100 fuel. In addition, compared to the standard diesel fuel of B100 fuel, there was a 6.64% reduction in engine power. Specific fuel consumption values for B100 and diesel fuels at 2200 rpm engine speed were 426.75 g/kWh and 355.22 g/kWh, respecti-vely.

The results obtained were compared with the values found in EN 14214 Biodiesel European Standards, and the density, kinematic viscosity, water content and sulfur content of the biodiesel fuel were found to be among the standard values
The viscosity of the biodiesel produced as reaction temperature 60 °C, alcohol and catalyst ratio 25% and 0.05%, was obtained as 4,372 mm2/s
Summary
The need for sustainable energy sources is increasing rap- tional systems [6, 7]. With the increase in en- lems such as carbon accumulation in the injector tip, dilution ergy use, there is a risk of exhaustion in fossil fuel (natural of the lubricant, excessive amount of engine deposits and gas, oil, coal, etc.) reserves where most of the energy needs wear in the cylinder liner occur. Many methods have been used in the re- to the effect of using biodiesel in pure or mixed form on ensearch and development of alternative energy sources, and gine performance and emissions, technical characteristics of biomass energy is of great importance among these methods the engine and test equipment under test, raw material of the [1, 2,3,4]
