Reason and Goal

The aim of the joint project is to develop a suitable no-harm application test for additives. The new test method is intended to map both current and future fuel and additive technologies as well as injection concepts. Furthermore, it should be meaningful not only for external but also for internal injector deposits, which are becoming increasingly relevant.

Summary

The subject of the method development is a combination of two complementary concepts, the "Diesel Deposit Formation Test" (DDFT, LKV) as a laboratory test and an application-oriented injector coking test ("ENIAK", OWI). Within the scope of the project, suitable boundary conditions, fuel references and evaluation criteria for the additive tests are to be developed first (setting of a basic performance). Subsequently, numerous fuel-additive combinations of antioxidants, cold flow improvers and lubricity improvers will be comparatively investigated and evaluated. The results of the method development will be documented in detail and made available to interested companies in a timely manner.

Currently, no-harm testing of additives is very complex and expensive. Therefore, there is innovation potential here for SMEs, e.g. additive formulators, analysis service providers, equipment manufacturers, to bring new products to market faster and more cost-effectively or to open up new business areas. Cost-effective screening by means of laboratory tests will make it possible to avoid expensive test bench tests in the future. At the same time, self-directed tests will be possible. IDIDs that occur can be detected sooner thanks to modern analysis technology, thus reducing or avoiding warranty cases in the field and recourse claims by customers.
