Description:

The FAME project consortium is pursuing an internal combustion engine concept to drastically reduce pollutant emissions from marine diesel engines. To achieve these goals, a combination of charge gas inerting and improved fuel-air mixture formation is essential, as a reduction in the oxygen content of the charge air is accompanied by an increase in particulate emissions and fuel consumption.

The aim of the University of Rostock's sub-project is to expand understanding of the chain of effects involved in mixture formation, with particular reference to medium-speed large engines, and to improve this understanding with a view to reducing exhaust emissions.

The project focuses on the following areas:

• Investigations into the influence of new nozzle geometries on fuel-air mixture formation
• Development and construction of a high-pressure, high-temperature (HD-HT) injection chamber for analysing fuel sprays in medium and large medium-speed engines under real combustion chamber conditions
• Support in the development of a prototype high-pressure injection system
• Investigation of injection and mixture formation in very large injectors under partial and full load
• Influence of oxygen reduction on mixture formation and ignition
• Systematisation of results for project partners in database and models
