Low temperature combustion (LTC) based on two-stage injection is the combustion mode which uses main injection to generate homogeneous charge and trigger injection to ignite. In this paper, the effect of injection ratio and starting-point of injection (SOI) of main injection on LTC were studied. The result shows that the trigger injection can control the process of combustion and make LTC more stable. Using trigger injection can effectively broaden the limits of SOI of the main injection. And the SOI of main injection is quite important for LTC. Inappropriate injection time will deteriorate the performance of LTC. By optimizing the SOI of main injection for specific injection ratios, effective control of the combustion phase can be realized and emissions can be reduced. (C) 2017 Elsevier Ltd.
