Operating Performance of a Tractor Engine of Emissions Standard EU IV in Biodiesel Operation

The use of pure biofuels in agricultural machinery offers the opportunity to reduce the use of fossil fuels. These engines are largely fuelled by self-consumption gas stations. Based on the introduction of new emission standards at the beginning of the decade it was determined that the engines have to comply with the emission limits regardless of the used fuel. At the Chair of Piston Engines and Internal Combustion Engines (LKV) of the University of Rostock it was investigated to what extent modern diesel engines for agricultural machinery are suitable for long-term operation with biodiesel fuel according to EN 14214.
Due to their high energy density, mainly liquid fuels of primarily fossil origin are used to power vehicles. In order to cut down the dependency on crude oil and greenhouse gas emissions at the same time, research has been carried out on alternative and renewable fuels for many years. With its action plan to promote biofuels, the EU Commission aims to replace...
The research project was carried out at the Chair of Piston Machines and Internal Combustion Engines of the University of Rostock and led by Prof. Dr.-Ing. Horst Harndorf and Prof. Dr.-Ing. Bert Buchholz. Thanks to the Federal Ministry of Food and Agriculture (BMEL) by the Fachagentur Nachwachsende Rohstoffe e. V. for supporting this project. Further thanks go to the Union zur Förderung von Oel- und Proteinpflanzen e. V., and the Arbeitsgemeinschaft Qualitäts-management Biodiesel e. V. Special thanks go to Deutz AG and its collaborator Adrian Tröger (exhaust-gas aftertreatment employee) and Dipl.-Ing. Markus Winkler (responsible for fuels and biogenic fuels).
