Endurance testing on engines and components is an important part of Research and Development work for improving the reliability and the service life of new parts in their development phase. The test equipment and test procedures have to be developed with respect to operational applications, legal requirements, user convenience and costs. Nevertheless, the basic goal is to get reliable data and sufficient information e.g. on fatigue strengths or strains from thermal loads. For these tasks only an extensive automatic system based on process computers fullfils the requirements. The VW endurance testing system will consist of engine test stands and component test stands on completion with test durations of up to 2500 hours per test. This paper describes the VW computer controlled endurance system for engines, starters and V-belts. The main subjects are the mechanical test object preparation and the parametric test description, followed by the presentations of essential endurance tests and the test evaluation. Besides good technical equipment operating supervision is an important tool to reach a satisfactory efficiency of the complete system.
