The effects of port injected n-heptane equivalence ratio and iso-octane direct injection timing are investigated experimentally and numerically. The results indicate that the combustion mode of iso-octane is dependant on the iso-octane direct injection timing corresponding to the stage of n-heptane HCCI combustion. In case of direct injection before the low temperature reaction of n-heptane, premixed combustion of the iso-octane occurs. In case of direct injection at the NTC period or the initial high temperature reaction stage of n-heptane, the iso-octane mainly undergoes premixed combustion.
