Summary
Optical measurement techniques have become an essential tool in the development of large gaseous fuelled engines with regard to high efficiency, high performance and low emissions. These goals can only be achieved by establishing carefully adapted combustion systems. The following paper presents measurements on various combustion concepts for large gaseous fuelled engines using fiber-optic measurement technology and computer tomography. Experimental investigations were carried out on a single cylinder research engine in order to analyze flame propagation and combustion anomalies with several configurations of the combustion chamber. These results also provide useful information to verify combustion and knock models for 3D CFD Simulation.
