Abstract

Homogeneous Charge Compression Ignition (HCCI) combustion has attracted considerable interest as a new combustion concept for internal combustion engines. HCCI combustion process has three issues to be resolved: ignition timing control, slower combustion, expanding stable operation region. In an earlier study, the ignition timing can be controlled and the rapidity of combustion can be lessened by using a fuel having two components with different ignition characteristics. In this study, ignition and combustion in an HCCI engine processes were investigated in detail by using spectroscopic measurements, and analyses of chemical kinetic simulations.
