In the middle and small scale diesel engine, the interaction between the spray wall-impingement and air motion plays a fundamental role on the mixture formation process, it also greatly influences the combustion process and the exhaust emissions. An experimental setup for spray impingement visualization has been made in this paper, the influences of common rail pressure and variable inclination angles on spray impingement are investigated. The experimental results show that the splashing volume increases according to the increasing common rail pressure, and the better atomization is achieved. As for variable inclination angle of spray, the upstream of impingement spray decreases and the downstream increases with the increase of inclination of the wall, the change of entrainment is hardly detected, but the overall splashing volume increases slightly.
