ENGINES | Planning Group 3 »Combustion CI«

Due to its very good efficiency, the compression-ignition engine has again become the “workhorse” of energy converters and has earned a leading role in many commercial applications that require the highest efficiency, robustness and economy while also subjecting the engine to high and continuous stress. Thanks to new technologies such as artificial intelligence, additive manufacturing and new combustion processes, engines with auto-ignition can meet higher requirements in terms of pollutant and CO2 emissions. FVV researchers and developers establish the scientific basis for this and transform the knowledge gained into practical applications.


» On the move towards zero-impact emission and climate-neutral powertrains we need a highly committed and application-oriented research platform such as that provided by the FVV. «

In the process, the research focuses are shifting away from gaining a basic understanding of technical matters – such as combustion process design – and towards optimising the overall powertrain system with regard to fuel consumption and emissions. Of key importance here is the question regarding suitable ways of achieving the CO2 targets set by legislators and, in the future, even complete climate neutrality. When using combustion engines, this can only be achieved by moving away from fossil fuels; as such, the interaction between powertrain and energy carrier and the coordination of combustion processes and fuel properties are gaining great importance as a research topic.

Advanced and future-oriented research on compression-ignition engines

Due to its outstanding efficiency, the diesel engine is the leader in many commercial applications. New technologies such as artificial intelligence or additive manufacturing can help to meet more stringent requirements for pollutant and CO2 emissions. The scientific basis is being worked out in projects of the Research Association for Combustion Engines (FVV) and can be transferred into practice by the member companies.

XME: Alternative fuels for the diesel combustion process

What is the potential of oxygenated methyl ether-based synthetic fuels for replacing fossil-based diesel in an compression-ignition combustion process? In the “XME Diesel” research project supported by FVV, funded as part of the “Neue Fahrzeug- und Systemtechnologien” [New Vehicle and System Technologies] specialist programme of the German Federal Ministry for Economic Affairs and Energy (BMWi), research institutes at RWTH Aachen University and the Technical University of Munich investigated the suitability of DME (dimethyl ether) and OME-1 (mono-oxymethylene ether) in collaboration with Denso, Ford and IAV. The main goal of the project was to adapt the combustion process to the physical and chemical properties of the new fuels in such a way that raw pollutant emissions are reduced significantly while the efficiency of the engine improves.
