The correct functioning and the durability of components is established long before the first prototype engine is running. AVL has dedicated test rigs to perform functional tests and initial durability checks of all major engine components and sub-systems, such as the valve train, lubrication and cooling systems, fasteners, gaskets, etc. Another task is to check and develop the fatigue life of major engine components.
Component and subsystem development is an important step towards reducing development time avoiding development loops, and increasing product quality, in order to get results at the earliest possible time.
