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.
