摘　　要：为深入分析不同气门控制策略对甲醇发动机性能的影响,本文以ZR180型号发动机为例,首先构建了发动机的仿真模型,并对其燃烧特性、扭矩、转速等关键参数进行分析。在当量比燃烧条件下,最佳气门升程设置可以最大化发动机性能;而在空气稀释燃烧条件下,调节节气门开度和进气可变气门升程(VVL)可以调整进气量,提高燃油效率并减少排放。将上述结果应用在实际生产中,取得良好的效果,具有较好的经济价值。In order to deeply analyze the influence of different valve control strategies on the performance of methanol engines,this paper takes the ZR180 engine as an example,first constructs a simulation model of the engine,and analyzes its key parameters such as combustion characteristics,torque,and speed.Under equivalence ratio combustion conditions,the optimal valve lift setting can maximize engine performance;Under air dilution combustion conditions,adjusting the throttle opening and variable valve lift(VVL)can regulate the intake volume,improve fuel efficiency,and reduce emissions.Applying the above results to practical production has achieved good results and has good economic value.
