摘要：To improve the efficiency of the internal combustion engine in a wider range of working conditions, multi-fuel combustion mode has attracted the attention of technicians abroad due to the flexibility to control the activity and concentration stratification of mixture in the cylinder. In this paper, new combustion model was used to analyse the effect of three injections of high-activity fuel in the cylinder on the reactivity stratification. Results showed that the injection strategies of adjusting highactivity fuel, such as early or late injection, the flexible ratio of three injections and injection duration, were able to implement the coupling control of the reactivity and concentration stratification of the mixture.
