| Abstract: | Nozzle atomization tests were carried out to study and obtain a SCR urea solution injection sys﹣tem which can meet the requirtments of diesel engines under varied working conditions. The tests studied two different nozzles respectively, including air auxiliary atomization and single﹣fluid pure liquid nozzles, and their atomization effect under different pressure, flow, measurement positions and when there was certain wind speed. The atomization effect means characteristic parameters such as average diameter of at﹣omization particles, atomization angles, etc. Research shows that compared with single﹣fluid pure liquid nozzles, air auxiliary atomization nozzles boast better performance. |
