Hydrocarbon thermal ignition in internal combustion engines is controlled by the balance of heat release rate by chemical reactions and internal energy formation or removal rate by adiabatic compression or expansion. Heat release rate can be described by a simple “Universal Rule”, that the heat release rate during the thermal ignition preparation period is determined by H2O2 loop composed of four elementary reactions. This rule was validated by sensitivity analysis and response analysis to perturbation of intermediate species concentrations. The rule was applied to clarify several subjects with experimental backgrounds, such as ignition characteristics of higher octane number fuels, an old and well-known knocking model and the influence of H2 addition.
