In this paper, numerical simulation is used to study the effect of injection mode on the flow characteristics of the flow field, which is divided into two parts: injection angle and injection hole shape. Combining with the parameters of fuel blending efficiency, penetration depth and total pressure loss, the effects of different injection modes on the flow field characteristics of the flammable combustion chamber were investigated. The conclusions are as follows: The jetting angle increases with the increase of jet penetration depth, but the blending efficiency decreases and the total pressure loss increases. Comparing with the other three types, the injection angle y = 5° Angle is more ideal; diamond hole in fuel blending, expansion to the expansion and the total pressure loss has obvious advantages, with better flow characteristics.
