12th International Symposium on Combustion Diagnostics

The understanding of the examination, analysis and optimization of a combustion engine is a core competence of engine manufacturers and suppliers.

In the period between the symposiums the question arises whether examination, analysis and optimization of a combustion engine are still worth holding a particular conference?

I think it is good to ask this ourselves again and again.

Because you always show us with your contributions and your interest that the understanding of these processes is a core competence of engine manufacturers and suppliers. It is the dominant energy conversion process that not only determines engine efficiency significantly but also defines which exhaust gas components the “chemical factory afterwards” has to manage.

Nowadays nobody is talking any longer about the near end of the combustion engine. Everybody knows that there will be a period of duality between electric and combustion engine in that each engine will develop itself and will find its “niche”. All this will not only be determined and driven by purely rational technical solutions but also the legislature intervenes into this market development. For this reason, Real Driving Conditions (as emissions are a result of the same) and friction reduction as a means of CO2 reduction are two main topics. Nevertheless, no one can predict the actual development of the markets and how customers really will (re)act.

Besides the development of the "optimum" internal combustion engines, the symposium is dedicated to methods and rapid measurement techniques that are necessary to that end. The measurement and analysis will be often completed by virtual sensors – these can be real pictures – and/or simulated signals which can be pictures as well. Capturing all important signals simultaneously and correctly as well as analyzing them efficiently and properly, is still a challenge for today’s engine developers. This is true both for individual subsystems as well as for the entire driveline system. In the latter case it is also important to understand the "cross effects" between the subsystems.


  • Visualization – What is the way forward?
  • Possibilities and limits of the combustion analysis
  • RDE requirements made on combustion diagnostics
  • Emission prevention already in the combustion chamber
  • Simulation in practice and in the future
  • How do I measure correctly?
