The LLNL Iso-Octane mechanism is a seminal chemical kinetic model developed by researchers at Lawrence Livermore National Laboratory. Iso-octane (2,2,4-trimethylpentane) is a primary reference fuel (PRF) used to define the octane rating of gasoline. Because of its importance in engine design, creating a robust mechanism for its combustion is critical for simulating engine knock, ignition delay, and emissions in internal combustion engines.

The LLNL iso-octane mechanism 2012 consists of 366 species and 1,578 reactions, making it one of the most detailed kinetic models for iso-octane combustion. The mechanism includes a comprehensive description of the reaction pathways involved in iso-octane combustion, including initiation, propagation, and termination reactions. The model also accounts for the formation of intermediate species, such as radicals and peroxides, which play a crucial role in determining the combustion characteristics of iso-octane.
