Project start: application tests for additives

Currently, no-harm testing of additives is complex, cost-intensive and of limited value for modern injection systems and future sustainable fuel blends.

With the aim of developing an application test for additives that reflects current and future fuel and additive technologies as well as injection concepts, the project "Development of a No-Harm Application Test for Additives - Investigations with the Diesel Deposit Formation Test and the ENIAK Test Bench" was initiated via the DGMK Technical Committee Fuels and in cooperation with the DGMK Additives Working Group.

BMWK Promotion

The BMWK is funding a research project on this, which started on October 1, 2022. The new test method is intended to take into account not only external but also internal injector deposits, which are becoming increasingly relevant.

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). The project will first develop suitable boundary conditions, fuel references and evaluation criteria for the additive tests. Subsequently, numerous fuel additive combinations of antioxidants, flow improvers, lubricity improvers and deposit control additives will be comparatively investigated and evaluated.

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.
