Abstract
Authors
describe construction and validation of an iso-octane model against various
experimental data including shock tube, jet-stirred reactor, flow reactor,
laminar flame speed and HCCI engine over wide operating conditions.
They built a skeletal chemical kinetic model of iso-octane oxidation
for an internal combustion engine that considers a combustion mechanism in two
parts: a comprehensive part describing reaction processes involving small
radicals and molecules as the ‘core’, and a skeletal one which, in coupling
with the ‘core’, controls the ignition characteristics.
