no combustion engine? no way

The Institute of Reciprocating Engines (Institut für Kolbenmaschinen, IFKM) at the Karlsruhe In-stitute of Technology (KIT) has worked for many years on various issues involving combustion engine improvement. As a matter of fact, combustion engines will continue as an essential element of partially electric drive-trains (range extender, serial hybrid). In the development of combustion processes, for example, we optimise in-engine processes to reduce fuel consumption and polluting emissions. This always requires the consideration of existing exhaust gas treatment systems as they strongly interact with the combustion engine. These issues are examined at IFKM as well. For this, IFKM carries out experimental examinations at state-of-the-art combustion engine test stations. This includes, in addition to comprehensive exhaust gas analyses, various endoscopic optical analysis methods which are minimally invasive and can be used in series engines too. Combustion engines are also simulated using the latest calculation methods in order to interpret experimental data in more detail and make forecasts for modified operating conditions. Combining combustion engines with electric motors means a significant change in the operating conditions of engines because, for example, the more frequent start and stop operations may lead to unfavourable conditions for exhaust gas catalytic converters.
