The Laboratory of Combustion Engines allows for measuring power, economic and emission characteristics of internal combustion engines in up to the power 230 kW/10000 min-1, or engines up to the power 400 kW/5000 min-1. The laboratory research focuses on applications of alternative fuels for internal combustion engines that are produced from renewable energy sources, especially on questions tackling mixture preparation and combustion, on tuning of engine parameters, on reduction of emissions of internal combustion engines, including reducing noise and vibrations, and on issues of electronic management of the engine. The laboratory also serves the needs of the teaching process, especially those related to bachelor, master and doctoral degree theses of students.
