Abstract

This work describes the development of a quaternary component chemical kinetic gasoline fuel model and its validation in context with shock tubes experiments and Spark Ignition (SI) engines. The model contains oxidation chemistry for Toluene, n-Heptane, Ethanol, and iso-Octane (THEO), as well as sub-mechanisms for simulating the formation of regulated \ce{NO_x} and soot precursor emissions. A virtual octane test simulator was also developed to model new experimental data obtained in Research Octane Number (RON) tests, for the first time results were used to benchmark chemical kinetic mechanism performance in a practical engine context with respect to other state-of-the-art detailed and comprehensive fuel models.
