The use of biofuels (biodiesel and gasoline-alcohol blends) in vehicle powertrains has grown in recent years in European Union, the United States, Japan, India, Brazil and many other countries due to limited fossil fuel sources and necessary reduction of anthropogenic CO2 emissions. European car manufacturers have approved up to 5 percent of biodiesel blend in diesel fuel (B5 biodiesel blend) which meets European fuel standards EN 14214 and EN 590. The goal for research is to achieve higher biodiesel content in diesel fuel B10 and B20, without resorting to larger diesel engines and fuel feed system modernization.

The paper evaluates the possibility of using different biodiesel blends (mixture of diesel fuel and Fatty Acid Methyl Esters) in modern Euro 4 direct-injection, common-rail, turbocharged, light-duty diesel engines. The influence of different quantity of RME in biodiesel blends (B5, B20, B30, B50) as well as neat RME on the emission measurement of gaseous pollutants, such as: carbon monoxide (CO), hydrocarbons (HC), oxides of nitrogen (NOx), carbon dioxide (CO2) and particulate matter (PM) for light-duty-vehicle (LDV) during NEDC cycle on the chassis dynamometer were analysed. All test results have been presented in comparison to standard diesel fuel.

Analysis of the measurements performed shows that the exhaust emissions are affected by the proportion of RME in biodiesel due to different chemical and physical properties of fuel blends.

The tests subject to analyses presented above have been performed in the Engine Research Department of the BOSMAL Automotive Research and Development Centre in Bielsko-Biala, Poland within the test program evaluating the biofuel influence on light-duty diesel engines for passenger cars and light-commercial vehicles.
