化油器是通用小型汽油机中最重要的装置,其作用是控制汽油机各工况油气混合浓度和燃油雾化混合质量.本文以168F汽油机化油器为例,应用两相流理论通过实验对油气混合过程进行分析,通过改变化油器各量孔和泡沫管参数匹配,控制混合气的浓度变化,从而有效改善通用小型汽油机的燃料经济性和排放,优化汽油机综合性能.
The Analysis of Two-phase Flow and Emissions on the Mixing of Air/fuel of Universal Small Gasoline Engine
Carburetors are the most important part in the fueling system of universal small gasoline engines. It is used to control the mix of air/fuel to provide air/fuel mixture of proper ratio to engines. The author will take the 168F carburetor for example to analyze the mixing of air/fuel by the two-phase flow theory. By adjusting the parameters of the carburetor to adjust the ratio of air/fuel mixture, we can meliorate the fuel economy and emission effectively, and optimize the general performance of gasoline engines.
