A Comparative Analysis of Different Cycle Diesel Engine Based on Three-Dimensional Simulation

Abstract:

The thermodynamic cycle analysis of diesel engines using the engine cycle simulation programs is feasible. The comparison of dual and LIVC miller cycles engine fueled with ED10 diesel/ethanol blends on temperature and emissions are investigated by simulation. From the comparison, +0.85 EIVC miller cycle is a selection for an optimizing point of miller cycle ratio, i.e, the intake valve timing of the engine is good for NO emission, SOOT emission and the engine power output. The difference of EIVC and LIVC miller cycle was studied. The results show the tendency of performance with EIVC miller cycle is similar to that of LIVC miller cycle. But the peak cylinder combustion temperature of EIVC miller cycle become lower relative to LIVC miller cycle, which lead to slightly lower NO emission and slightly higher SOOT emission for EIVC miller cycle.
