The authors have developed a control technique of mixture distribution, ignition and combustion processes by use of dual-component fuel and/or two-stage injection. It is still necessary to develop an understanding of the effects of the mixture distribution conditions on the spatial-temporal ignition and combustion processes for further advancement. The present study conducts a fundamental experiment in a rapid compression and expansion machine which uses two injectors. The ignition, combustion and emissions characteristics are investigated for injection timings and mass ratio of fuel injected from two injectors by pressure history analysis, optical diagnostic and burnt gas measurement.
