Abstract

The use of fuels from renewable energy sources is no longer a matter of individual commitment to reduce emissions contributing to air pollution from exhausts of road vehicles, but a matter of comprehensive strategy to improve the foundation and development of the global energy sector, and to provide a targeted contribution to the reduction of environmental pollution. Underlying the importance of this determination, the framework of international agreements clearly states certain objectives to be achieved in the future. However, when setting targets for increasing the scope of use of biodiesel, it is important to take into account the availability of such fuel, as well as the possibilities of its application in the existing vehicle fleet. Given the fact that sources of raw feedstock and the technology for obtaining biodiesel are still at the level that cannot cover the needs of the entire market, coupled with the fact that the existing vehicle fleet is primarily suited for the use of conventional fossil fuels, using a mixture of these two fuels can be an interim solution. This paper considers the use of fuel blends of conventional fossil diesel fuel and bio diesel in diesel-powered internal combustion engines designed for on-road applications. It analyzes the trends of energy performance (power; torque; specific fuel consumption) and environmental properties of diesel engines (emissions of polluting substances), depending on the percentage of bio diesel in fuel blends.
