The Large Engines Competence Center, LEC for short, is one of the world’s leading research institutions for large engine technologies and develops innovative solutions for sustainable energy and transport systems. Since 2015 we have been a funded COMET K1 Center (LEC EvoLET). With our research, our unique infrastructure and our international network of partners, we make a significant contribution to massive emission reductions and efficiency improvements. The focus is on the use of renewable energies, digital technologies and the optimization of the overall system. With the COMET module LEC HybTec, the research focus is even more on the integration of big data methods in order to map phenomena that could not be modeled so far.
