摘　　要：我们以一型号为192F型汽油/液化石油气两用燃料通用小型发动机为研究对象,介绍了该发动机的燃料供给系统结构,并根据此类发动机排放测试标准GB 26133-2010进行汽油和液化石油气2种燃料的排放性能试验。通过对试验结果的分析,该发动机燃用液化石油气比燃用汽油CO排放量降低,NOx排放增加。In this article,a 192F gasoline/liquefied petroleum gas dual-fuel general utility small engine is used as the research object.The article introduced the fuel supply system of the engine,and completed emission performance tests for gasoline and liquefied petroleum gas according to the emission test standard GB 26133-2010.Analysis of the test results shows that the LPG fuel used by this engine reduces CO emissions and increases NOx emissions compared to fuel gasoline.
