摘　　要：由于螺旋进气道特性显著影响发动机的燃烧和性能 ,因而对其生产 ,加工要求很高。作者进行试验模拟各种制造偏差 ,并分析偏差对气道性能的影响 ,从而进一步探索减少偏差的方法 ,提高进气道的制造精度 。The characteristic of the helical intake port has great influence on engine combustion and performance.Therefore,the strict production requirements are needed in the process of port casting and machining for many errors or deviations may occur.An experimental research has been made by simulating the different kinds of deviations to verify how the errors or deviations affect the performance of the helical inlet port in order to improve the production precision so as to insure good engine performance.
