Abstract
An experimental and numerical investigation of commercial gasoline (octane number = 90) with a reference fuel (PRF87) was accomplished. Laminar Flame Velocities and Markstein Numbers of these fuel-air mixtures were investigated and compared with each other and with numerical results. PRF87 is presented as a reference fuel for gasoline defined as 87 percent Iso-Octane and 13 percent N-Heptane by volume at ambient conditions. Spherical flames of gasoline- and PRF87-Air-Mixtures at initial temperature of 373 K, initial pressure range from 10 bar to 25 bar and equivalence ratios from φ = 0.7 to φ = 1.2 were experimentally investigated using the Constant Volume Bomb Method.
