摘要：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。

Abstract：The paper carries out simulation analysis
to working process of a four cylinder gasoline 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.
