Interactive Lab Assistant: Replacement of a timing belt at a OHC engine

The multimedia course “Changing timing belts in overhead camshaft engines” provides a detailed description of the procedure for changing toothed belts in an engine with an overhead camshaft and explains the specific aspects in a comprehensible way. The course not only explains precisely how a timing belt works but also makes reference to the necessary theoretical background which is necessary to understand the course contents. This theory is imparted by means of numerous animations, pictures and video in a way that is easy for trainees to understand. The interactive experiments and tests of knowledge enhance and monitor the theory learned, allowing the essential diagnostic skills to be taught. Thanks to the practical educational focus of the course, the knowledge gained can be directly applied in practice. For example, the course includes diagnostic instructions for checking a belt drive when the engine is not running properly. Documentation of measurement results makes it possible for trainees to recapitulate the things they have learned in preparation for exams.
