%X 运用GT-Power建立发动机计算模型, 研究气门型线、进气歧管形式对1.5 L Atkinson循环发动机经济性和动力性的影响; 运用CFD软件AVL-Fire对不同燃烧室形式下的燃烧过程进行模拟研究, 并通过台架试验数据进行验证．研究结果表明：最佳进气持续期为240° CA, 气门最大升程为8 mm．此时, 长度为300 mm的侧面进气的进气歧管与改进的燃烧室匹配, 在研究转速范围内, 最低油耗比原机降低了7.23～8.31 g/(kW？h), 且低油耗区范围明显扩大; 长度为100 mm的中间进气形式歧管的最低油耗比原机降低了6.21～9.19 g/(kW？h), 低油耗区范围也有明显扩大; 两种形式的进气歧管皆可以满足降低油耗的需求, 需根据发动机实际布置情况进行选择．<br>To study the fuel economy and dynamic performance of a 1.5 L Atkinson cycle engine，a GT-Power(1-D)simulation model and AVL-Fire(3-D)computational model were built and calibrated with experimental data. The research was conducted by changing intake valve profile，intake manifold forms and chamber shapes. The results demonstrate that the perfect intake duration and maximum valve lift are 240° CA and 8 mm respectively. 300 mm intake manifold was matched with an improved chamber leading to a range of 7.23―8.31 g/(kW？h) reduction in fuel consumption with the speed that has been studied，and the engine can get a low fuel consumption under the load condition and speed range commonly used. An intermediate form of intake manifold was matched with the improved chamber，with a range of 6.21―9.19 g/(kW？h) reduction in fuel consumption at the studied speed. These two forms of intake manifold have both expanded the area of low fuel consumption significantly. Both forms of the intake manifold can meet the need of the engine and should be applied according to the actual arrangement of the engine
