In this study, the emission characteristics of gasoline split injection were investigated in a single cylinder spray guided DISI experimental engine under lean stratified conditions. The split ratios were 7:3, 5:5, and 3:7 by fuel mass. From the results, there was certain dwell time about 6CAD for the highest IMEP with the split injection strategy. If the dwell time was increased, the density of stratified mixture was lowered. Therefore, the combustion intensity was decreased, which resulted in the retard of combustion phase. The retard of combustion phase caused the increase of IMEP compared to single injection. However, the dwell time which is longer than 6CAD reduced the combustion efficiency resulted in the decrease of IMEP. Both NOx and Soot emissions were reduced with split injection due to the fact that the local fuel rich area was decreased especially when the quantity of the first injection of split injection was larger. However, the HC and CO emissions were increased with split injection due to overmixing of stratified mixtures.
