The work presented is divided into two related projects. The first investigates the possibility of using blends of renewable fuels with fossil Diesel, and fossil-free blends, in existing Diesel engines. The second examines the performance of renewable fuel blends when used with a new combustion strategy for advanced engines – partially premixed combustion.
“The tested renewable fuels yielded slight increases in engine thermal efficiency while significantly reducing soot emissions in engines with production settings. The use of partially premixed combustion with renewable blends yielded further improvements in thermal efficiency while reducing both soot and nitrogen oxides emissions” says Tankai Zhang,
These findings show that by combining renewable fuels with innovative technical solutions, the internal combustion engine can contribute to the development of sustainable transport and play an important role in the societies of the future.
“The results will help the industry to know more details about the biofuels and to be prepared for future regulation.”
