摘　　要：分别以生物质空气气化气和富氧气化气作为机动车燃料,从行驶和排放特性2个方面进行了试验研究。结果表明:相同条件下,燃用生物质空气气化气行驶里程是富氧气化气的1/3,燃用生物质富氧气化气的行驶里程是天然气的1/3;燃料(气体组分)变化对机动车尾气中一氧化碳排放影响较小,过量空气系数对一氧化碳的排放量具有决定性作用;以生物质空气气化气作为发动机燃料时,碳氢化合物排放量较低,以生物质富氧气化气作为发动机燃料时,碳氢化合物排放量较高,但排放趋势相似;燃料(气体组分)变化对氮氧化物排放起决定性作用;而温度是影响热力型氮氧化物排放的主导因素。生物质气化气是一种清洁、可再生的代用燃料。The producer gases derived from air and oxygen rich biomass gasification were used as the vehicle fuel for testing the running performance and its emission behavior. The results were as following：under the same road condition and for the same vehicle, the kilometers of travel with air gasification producer gas as fuel were one third of that with oxygen rich gasification producer gas as fuel, and the kilometers of travel with oxygen rich gasification producer gas as fuel were one third of that with CNG as fuel;the producer gas composition had little influence on the carbon monoxide emission in the exhaust gas, but the excess air ratio had crucial impact on the carbon monoxide emission;with air gasification producer gas as fuel, the content of the hydrocarbons in the exhaust gas was lower, and it was higher when being with oxygen rich gasification producer gas as fuel,for both fuel gases, the content of the hydrocarbons had the same tendency of increasing along with the increasing of the RPM of the engine;the producer gas composition had definite influence on the NOx emission in the exhaust gas, meanwhile, the temperature was the dominating factor of the thermal NOx emission. The results showed that the biomass gasification producer gas could be a kind of clean and renewable substitute fuel.
