Dynamometer durability testing plays a very important role in engine design verification process as it is still the most reliable method to ensure the product quality before starting mass production. To ensure that the new engine as designed and manufactured will perform in a manner that increases customer satisfaction, the stresses present in the dynamometer durability test has to be representative of those an engine will meet in customer usage. Thus, it is an important task to derive proper test cycles for dynamometer tests as they should definitely be correlated to customer usage in order not to under/over-test the subject. Customer-Correlated General Durability (CCGD) test, which targets system-to-system interactions rather than component-specific or subsystem-specific failure modes, is developed in this manner. In current CCGD cycles used in engine companies, state speed/load residencies reflecting the overall lifetime driving of the engine of concern is taken into account with randomized ramp-up and ramp-down stages to cover transient driving conditions. The cycle creation method can be divided into two phases: Data Collection & Data Analysis. Also there are two types of data used: Vehicle Data & Customer Field Data to obtain real world customer usage profile.
