This project will investigate the fundamentals of fuel spray development in Direct-Injection Spark-Ignition (DISI) engines. Key areas of study will include full-bore fuel spray formation and wall impingement imaging in an optical engine and correlation with gaseous and particulate exhaust emissions. Spray formation and impingement tests will also be conducted in a constant volume fuel injection chamber at controlled thermodynamic conditions. Wall heat transfer at locations of impingement will also be studied. The combination of these research methods will give a full picture of in-cylinder effects related to various engine operating regimes and injection strategies. Surface treatments to reduce the effects of fuel wall impingement will also be explored.

该项目将调查直接注射火花点燃（DISI）发动机中燃油喷雾剂开发的基础。研究领域将包括光发动机中的全孔燃料喷雾形成和墙壁撞击成像，以及与气态和颗粒排气排放的相关性。喷雾形成和撞击测试也将在受控热力学条件下的恒定体积注入室中进行。还将研究撞击位置的壁热。这些研究方法的结合将提供与各种发动机操作制度和注入策略相关的缸内效应的全面图。还将探索以减少燃油壁撞击影响的表面处理。
