Research Fuelss

In recent years problems have been reported in engine operating characteristics and in dynamic injector behavior related to fuel-based deposits inside common rail injectors. The reasons for the formation of deposits are very complex and include both fuel-side and design influences. Cause clarification can often no longer be achieved with complex and expensive engine tests/injection bench tests. Therefore, there is a high demand for a simple and widely available laboratory test for preventative fuel screening. At the Department of Piston Machines and Internal Combustion Engines of the University of Rostock, in a FVV research project a test method was developed to evaluate the deposit forming tendency of diesel fuels inside of common rail injectors.

1 Motivation

The introduction of stricter emission legislations requires a steady development of the diesel engine combustion process. The trend goes towards increasingly complex components; whose secure functionality is only possible by...



The FVV research project Development of a Laboratory Test for the Tendency of Diesel Fuel Fouling was performed at the Institute of Piston Machines and Internal Combustion Engines under the direction of Prof. Dr.-Ing. Horst Harndorf and Prof. Dr.-Ing. Bert Buchholz. The project was funded by the FVV from own resources and conducted by an expert group under the direction of Dr. Alexander von Stockhausen (Robert Bosch GmbH). The authors greatfully acknowledge the support received from the Research Association for Combustion Engines (FVV) e.V. and from all project participants. We would like to thank Dipl.-Ing. René Junk for carrying out the tests on the injection system test bench. The laser scanning microscope used was funded by the European Regional Development Fund (ERDF) under the 2014-2020 Operational Program to promote research skills at universities and non-academic scientific equipment.
