摘要

In this study, we investigated the potential of combustion control of a diesel engine operating in homogeneous charge compression ignition (HCCI) mode through 1-D engine gas dynamic simulation (AVL BOOST). Effects of parameters including the content of residual gas, the ratio of external EGR, and its temperature on engine thermal efficiency were studied. The results showed that the engine efficiency increased with more residual gas at lean conditions. The temperature of recirculated exhaust gas is an important parameter for auto-ignition timing control. As the exhaust gas temperature becomes higher, combustion initiation occurs earlier, further results in the reduction of engine efficiency. The indicated efficiency of the engine operating in HCCI mode peaks at 43.19% with lambda of 3.53 without EGR. The simulation predicts that the efficiency can be improved to 44.07% by using leaner mixture and EGR.
