摘　　要：针对6105ZQ增压中冷发动机开发出了6105ZQS柴油-天然气双燃料发动机。为了进一步对6105ZQ双燃料发动机进行性能研究,针对燃烧室结构参数、供油提前角、天然气替代率等对双燃料发动机性能有重要影响的因素进行了试验,研究其对发动机性能、缸内压力升高率、放热率以及缸内温度的影响,为今后开发天然气电控喷射式双燃料发动机及提高其性能提供依据。In this thesis, NG -diesel 6105ZQS dual -fuel engine is developed on the turbocharged inner -cooled 6105ZQ engine. To further investigate the performance of dual - fuel engines, the performance factors included in the experiment study such as： structure parameters of combustion chamber, fuel - supply advance angle and substitution ratio of NG to diesel are tested. Their effects on engine operation performance, in - cylinder pressure, pressure increase rate, heat release rate, as well as in - cylinder temperature are studied, which provide a basis for future research and development of electrically controlled injection dual - fuel engines and for performance improvement of dual - fuel engines.
