The oxidation of syngas mixtures was investigated experimentally and simulated with an updated chemical kinetic model. Ignition delay times for H 2 /CO/O 2 /N 2 /Ar mixtures have been measured using two rapid compression machines (RCM) and shock tubes at pressures from 1 to 70 bar, over a temperature range of 914-2220 K and at equivalence ratios from 0.1 to 4.0. Results show a strong dependence of ignition times on temperature and

iso-Octane (2,2,4-trimethylpentane) is a primary reference fuel and an important component of gasoline fuels. Moreover, it is a key component used in surrogates to study the ignition and burning characteristics of gasoline fuels. This paper presents an updated chemical kinetic model for iso-octane combustion. Specifically, the thermodynamic data and reaction kinetics of isooctane have been reassessed based on new thermodynamic group values and recently evaluated
