Abstract:A diesel surrogate fuel includes n-decane, iso-octane, toluene, and
   methyl cyclohexane was constructed. A skeletal oxidation mechanism
   composed of 70 species and 193 reactions was developed by a decoupling
   methodology for the diesel surrogate fuel. Based on the decoupling
   methodology, the skeletal mechanism is divided into two parts: one is an
   extremely simplified C_2-C_n model to predict the ignition delay time
   and consumption of fuel, and the other is a detailed H_2/CO/C_1
   mechanism to predict laminar flame speed, extinction strain rate, as
   well as hydrocarbon and carbon monoxide emissions. By comparing with the
   measurements in ignition delay in shock tube, species concentrations in
   jet stirred reactor (JSR), laminar flame speed, as well as combustion
   and emissions of premixed charge compression ignition (PCCI) for diesel
   oxidation, it is indicted the predictions agree with the experimental
   data reasonably well.
