Effect of adding soybean oil to diesel fuel on engine characteristics

Biodiesel fuels are seen as an important resource due to the environmental damage caused by exhaust emissions from the use of fossil fuels, the increase in global warming and the rise in oil prices. As an alternative, the use of biodiesel by blending certain percentages of biodiesel into diesel fuel is preferred due to both sustainability and some advantages. In this study, 10% soybean oil was added to the fuel used in a single-cylinder diesel engine and the changes in engine power, fuel consumption and exhaust emissions were experimentally investigated. According to the results of the study, it was observed that the engine power was almost the same with the addition of soybean oil to the diesel fuel, but there was an increase in exhaust emissions with some increase in fuel consumption. For this reason, it is clear that further experimental studies should be carried out by adding soybean oil with different characteristics and proportions to be used in diesel engines.
