High demands are placed on large gaseous-fuelled engines regarding performance, fuel consumption and emissions. Because of the different applications of gaseous-fuelled engines (block-type thermal power stations, generation of electric power in a stand alone plant, etc.) and the use of different kinds of gases (natural gas, wood gas, pyrolysis gas, dump gas, etc.), the optimization process can be seen as a very complex task. Today engines have already reached a high level of development and further improvements can only be realized with very high expenditures. Experience has shown that a purely experimental approach is no longer sufficient and therefore the application of modern simulation tools is necessary. In this paper a combined development process is described consisting of simulation, experimental investigations on a single cylinder research engine and transfer on a full scale engine as an example for the optimization of a gas-purched prechamber concept.
