基于GT-Power的汽油机三级可变进气系统研究

摘要

The paper carries out simulation analysis to working process of a four cylinder gaso line engine by using the GT - Power software, analyzes the influence of the various length of intake pipes on the engine dynamic performance as well as it influencing law, which is verified by tests. A control strategy is concluded to determine the variable length of the intake manifold for the gasoline engine and a model of intake manifold is established relative to the control strategy.%利用GT-Power软件进行某四缸汽油发动机工作过程仿真分析,分析计算进气系统管道长度变化对汽油机动力性能的影响及其规律,并得到了试验验证。总结出一套确定汽油机进气歧管长度三级可变的控制策略,并建立了改进后的与控制策略对应的可变进气歧管汽油机模型。
