Abstract
Gasoline surrogate mixtures consisting of five components, isooctane (branched-chain alkane), n-heptane (straight-chain alkane), methylcyclohexane (cyclic alkane), toluene (aromatic), and diisobutylene (alkene), were proposed and a corresponding detailed chemical kinetic model for combustion, SIP-Gd1.0 (SIP gasoline surrogate detailed kinetic model revision 1.0), has been constructed. The mechanism well reproduces the ignition delay times measured by shock tubes and laminar premixed flame propagation velocities of air-mixtures of each component, two and three components mixtures (PRF and TRF), and five-component surrogate mixtures corresponding to JIS 2nd grade gasoline ("regular") S5R and 1st grade gasoline ("high-octane") S5H.
