摘要：

KIVA is used to simulate and analysis the impact on the performance of low-temperature combustion diesel engine at different EGR rate and injection timing. The results show that high EGR rate can effectively reduce the in-cylinder combustion temperature, but with the increasing of the EGR rate, diesel Soot emissions will increase at a certain extent. Late spray can achieve better low temperature combustion of diesel engine, which can also reduce both diesel NOx and Soot emissions; but if it sprays too late, NOx and Soot emissions will have a slight rebound.
