LEDF - Low Emission Dual Fuel
LEDF is a joint research project funded by the
BMWi (Federal Ministry of Economics and Technology).


Within this project the Chair of Piston Machines and Internal Combustion Engines (LKV) and the Chair of Technical Thermodynamics (LTT) of the University of Rostock are working together with partners from the industry. The scope of work is the research and development of a next generation combustion processes for medium-speed diesel engines for marine applications. The focus lays on the combination of common marine fuels on the one hand and natural gas on the other hand. By using this so called dual-fuel technology the NOx-emission limits of the International Maritime Organization (IMO) shall be deceeded significantly. These limits are coming into force in 2016.

For the realization of the venture a new single cylinder research engine is built up in the test bed field of the two chairs. After the finalization of the setup phase this engine will be one of the largest of its kind worldwide. The first project phase is characterized by the development of entirely new CFD approaches and methods in parallel to the installation of the needed infrastructure for the single cylinder engine. The project partners will be equipped with a truly powerful tool, due to the combination of simulation and engine testing, which will be for the first time in this technological depth. By using this tool it will be possible to identify constructive and process strategically measure packages to gain significant efficiency improvements.

The potential of specific measures to reduce the emission amount and to increase the power density at the same time can be verified at the real testing device. The precise interplay of simulation and engine testing is capable to lead to a sustained reduction of the developing time of modern propulsion systems for ships.

The project contents and results shall be published to a wide scientific and industrial community with the help of workshops and professional publications.
