Abstract

A novel injection strategy is proposed to realize PCCI combustion for marine diesels of large-bore and yet longer-stroke dimensions. This strategy utilizes a set of sprays from closely aligned holes having injection directions intersecting one another so as to cause mutual interaction and merger of the sprays by overlapping injection periods and applying different injection rates. It is feasible to improve the mixture stratification in a combustion chamber. Moreover, LCO (Light Cycle Oil) and its water-emulsification are newly introduced to realize the ignition control of PCCI combustion in this study. The potential of the strategy for PCCI combustion was successfully examined through observation of the spray merging process and combustion process in a rapid compression-expansion machine.
