In the preceding Chapter 6 it has been shown that the combustion of a simple fuel like hydrogen (2 H2 + O2 → 2 H2O) requires nearly 40 elementary reactions for a satisfactory chemical mechanism. For combustion of hydrocarbon fuels, as simple as methane CH4, the number of elementary reactions in the chemical mechanism is much larger. In some cases several thousands of elementary reactions (e. g., in the case of autoignition of the Diesel fuel with the typical component cetane C16H34; see Chapter 16) influence the overall process.
