Abstract:
The present study introduces an injection technique for Premixed Charge Compression Ignition (PCCI) combustion in marine diesel engines. It aims to improve the controllability in the spray propagation and obtain the ideal mixture formation through the use of behavior of a merged spray which is formed by a mutual spray impingement between two sprays.Experiment was carried out to confirm the feasibility of controlling the spray propagation in a constant volume chamber. Further, the effects of merged spray propagation on mixture formation, ignition and combustion process have been investigated in a Rapid Compression Machine (RCM).
