The reduction of CO2 emissions has become a major issue on a broad area of technologies with economic and social relevance. One of the major contributors to CO2 emissions over the next decades are internal combustion engines and thus the reduction of those emissions is important. Furthermore it is mandatory to improve internal combustion engines with respect to efficiency and low local emissions like NOX and hydrocarbons.
To address these issues a comprehensive understanding of the underlying physical and chemical processes is necessary. Recent advances in the automotive industry have led to the downsizing of the internal combustion engine geometry, which increases the surface-to-volume ratio of the engine. To this regard, near-wall reactions become increasing important for flame quenching and unburned hydrocarbon emissions. In combination with numerical simulation research in this field leads to improved combustion efficiency and engine development.
