The publication presents test results for a Perkins 1104D - 44TA engine powered by SME sunflower oil fatty acids methyl esters. The SME biofuel was manufactured in-house using a GW-200 reactor at MCOŹE "BioEnergia". The test was carried out at an engine test stand at Kielce University of Technology's Heat Engine Laboratory. During the test the engine operated according to an external speed characteristic. The tests aimed to determine the impact of using an SME type biofuel to power the engine on the engine's primary performance indicator values. A slight decrease to the brake horsepower and torque of the tested engine powered by sunflower oil esters as compared to diesel was recorded. Fuel consumption of the engine powered by plant origin fuel also increased. No operating problems were experienced associated with powering the engine using sunflower oil esters during the tests.

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.
