In our premises, in our workshop and our engine test stands, we always offer maintainance courses. We teach the participants how to handle our CFR engines and our BASF engines. We train the participants in many directions so that they are able to operate and maintain the test engines independently. Cetan numbers and octane numbers are determined in practical tests for the trainings so that the participants are provided with in-depth theoretical as well as practical knowledge. The maintenance routines of the engines are also dealt with in practice.
