Fuels constitute one of the research areas within the scope of piston internal combustion engines. The works encompass both conventional as well as alternative fuels. Fuels are sought which will contribute to a reduction in the negative impact of transport on the natural environment and humans. These may be fuels obtained from organic raw materials of agricultural (most often) or forest origin. When it comes to compression-ignition engines, Biodiesel B100 type biofuels can be used to fuel them, which most often constitute a long chain fatty acid ester, made from plant oils or animal fats. The publication presents ecological indicator test results for a compression – ignition engine fuelled by SME Biodiesel, or sunflower oil methyl esters and commercially available diesel as a benchmark. During the tests, the engine operated according to load characteristics at two different crankshaft rotational speeds. A sunflower oil ethyl ester fuelled engine returned beneficial values for most of the tested ecological indicators as compared to a diesel fuelled engine. Concentrations of substances such as CO, CO2, unburned hydrocarbons (THC), particulate matter (PM) were lower in the engine emissions, exhaust smoke levels were also reduced. Only nitrogen oxides (ONx) increased.
