Abstract

In this study, CONVERGE was used to examine the effects of the injection angle on the flow field, flame propagation, combustion,and emission in the engine cylinder. With oblique injection close to the intake valve,a stratified engine mixture that is thin in the middle and thick at the edges is formed in the Z-plane. The peak cylinder pressure is increased by 9–23 %.In addition,the centre of gravity of combustion is moved closer to the upper limit by 6–17.8 %,and it shows a tendency of rapid advancement followed by a delay. The maximum NOX emission is 1.35 g•(kW•h)−1,and it decreases gradually. CO,HC,and unburned methanol emissions decrease initially and then increase. The lowest unburned methanol emission is 5 g•(kW•h)−1, and the maximum formaldehyde emission is 5 × 10−3 g•(kW•h)−1. When compared with horizontal injection,IA-35 is optimal in terms of both combustion and emission. Therefore,the injection angle should be set appropriately for the dual collision of fuel with the lower intake tract wall and valve tappet position.
