Effects of the split injection pattern on combustion and emission characteristics of a D.I. Diesel engine with a common-rail injection system were investigated. While keeping the injection pressure and total injection quantity constant, the ratio of amounts of fuel injected between two injection pulses and the injection interval were varied, and the emissions and performance of a D. I. Diesel engine with a common-rail injection system were measured. The concentration distributions of the vapor and liquid phases in the splitting fuel spray injected into a high-pressure / high-temperature vessel were measured by means of the laser absorption scattering (LAS) technique. The results account for the effects of the split injection pattern on the combustion and emission characteristics.
