| Abstract: | This paper, taking the ＆quot;Great Wall GW2.8 Electric Injection Sprays Characters＆quot; as a topic, by adopting the contrast experiment method, and building high pressure common rail injector test bench experiments, takes the injector air-gap gasket as the main research object, and analyzes the main influencing factors of injector sprays characters through comparison. The results show that changes of injector air-gap gasket thickness have a significant effect on cyclic injection quantity of four operating point：emission point, full load point, high pressure injection point and low pressure injection point. The influencing factor is the change of trigger of start time and power-off time. |
