摘　　要：节能减排已成为当今发动机发展的重要方向之一,而燃烧过程将直接影响发动机的经济性与排放性。通过模拟软件模拟分析了某125mL发动机燃烧室选用单火花塞和双火花塞时气缸内的燃烧进程、燃烧生成物速率及缸内湍流火焰速率。通过模拟结果可发现,双火花塞气缸内燃烧效率、生成物速率均好于单火花塞气缸内的燃烧效率、生成物速度;双火花塞气缸内的湍流速度要高于单火花塞气缸内的湍流速度。模拟计算结果为汽油机节能提供了一种有效途径,将为汽油机提高经济性提供一定的理论借鉴。The energy saving and emission reduction（ESER） has been one of the most important directions of internal combustion engines,and the combustion process would affect the economics and exhausting performance of an engine.In this paper,a simulation software has been used to generate data of the combustion process,the rate of combustion products developed,and turbulence flame rate in a 125ml engine with single plug and double plugs.The results show that the engine with double plugs has a better performance than single plug one in the combustion process,the rate of combustion products and turbulence flame rate.The simulation results prove an effective method for gasoline engine to save energy,which can also provide a theoretical support for improving economy performance of gasoline engine.
