The work aims to understand how the autoignition process is affected by the thermodynamic conditions found in spark ignition engines. Auto-ignition, which is related to the knocking phenomenon, is the main limiting factor in the thermal efficiency of these machines. Understanding the main physical-chemical parameters of fuels related to the physical conditions imposed by the engines and how they interact with each other is fundamental for the design of new, more efficient equipment and, consequently, with lower emissions of toxic and greenhouse gases. Thus, in the present work parametric studies are developed related to the dynamics of low temperature chemical kinetics (LTC) responsible for initiating the knocking process in spark ignition engines. Furthermore, due to the auto-ignition tendency of the reactant mixture provided by the engine conditions, the LTC is responsible for changing the burning rate of the main flame, increasing the flame propagation speed. Therefore, this work also addresses the structural changes and burning rate in the flame caused by LTC, which causes it to interact directly with the engine's auto-ignition process.
