DEVELOPMENT OF COMBUSTION CONCEPTS FOR LARGE ENGINES BASED ON SINGLE CYLINDER RESEARCH ENGINES
The high requirements to modern large engines regarding power output, fuel consumption and emissions can only be achieved with carefully adapted combustion concepts. The development performed at multi-cylinder engines is very expensive and results in high costs. Therefore the use of single cylinder engines is preferred, especially in the early phase of engine development. At LEC two single cylinder engines have been established. These two research engines are designed to be very flexible and can be rapidly converted into different bore/stroke dimensions. Besides conventional fuels like diesel and natural gas, the engines can also be operated by alternative fuels such as DME, hydrogen and various gas mixtures. In this contribution the engine development methodology for large gas and large diesel engines based on single cylinder research engines (SCRE) is presented. The research work is carried out with the intensive support of simulation work and modern measurement techniques. Engine working cycle simulation is executed in this process in order to ensure the transferability of the results of the SCRE to the corresponding multi-cylinder engine.
