| 摘 要： | CNG发动机与汽油机的燃烧同为预混湍流燃烧,但火焰传播速度、着火延迟期及混合气热值均不同。为在汽油机上改燃CNG或CNG/汽油两用燃料发动机发挥CNG燃烧的优点,针对CNG燃烧特点设计发动机,才能达到较高的输出功率和较低的排放。

| Abstract: | The combustion of CNG engine and petrol engine is the premixed turbulence combustion,and the flame burning velocity,combustion delay period,the heating value of charge are different,so that combusting CNG in petrol engine or CNG/petrol dual fuel engine can't develop advantages of CNG.Only design in engine directing toward characters of CNG combustion can improve output of engine and reduce exhaust of engine. |

| Keywords: | CNG engine combustion process flame burning velocity ignition delay period exhaust emissions |
