Combustion Diagnostics

A large field of application of optical diagnostics is the process optimization of combustion engines. The 4-stroke internal combustion engine will probably be the most important and most reasonable engine in the medium term, despite the hybrid- and fuel cell engines. Regarding stronger emission limits (e.g. CO2-emission) and diminishing resources, the urgency for the improvement of combustion engines rises. Optical measurement techniques are necessary for the development of new and improved combustion processes. These methods detect parameters which are relevant for combustion like mixture formation, distribution of the air/fuel-mixture, in-cylinder flows, charge temperature or the distribution of residual gas. These parameters give the application engineers information about the effects and results of developments.
