摘　　要：应用AVL BOOST软件建立某四缸汽油发动机热力学仿真分析模型,计算进气管道长度变化对汽油机性能的影响,通过对计算结果的比较和分析,确定两级可变进气歧管长管和短管的长度,以在较宽的转速范围内,提升发动机的动力性。A thermodynamic simulation analysis model of a particular 4-cylinder gasoline engine is constructed using the software AVL BOOST to calculate the effect of intake manifold length change on gasoline engine performance. By comparing and analyzing the calculated results, the lengths of long and short two-level varia- ble intake manifolds are determined so that engine power performance can be improved at a wider speed range.
