INTRODUCTION OF THE LABORATORY

The Engine Test Beds provides comprehensive testing of internal combustion engines and measurement of combustion process, engine dynamics, friction, wear, and emissions. The laboratory has two full-function engine test beds and one friction measurement testbed. The operation of the test beds is assisted by equipped preparatory workshops. In the laboratory, it is also possible to perform full scale tests of internal combustion engines and of individual components separately. On the test beds, a complete measurement of the emissions of internal combustion engines can also be performed.
