根据相关规程要求,对-7℃时的发动机冷起动特性进行试验。选用汽油和体积分数为20%的丁醇汽油混合燃料进行对比研究,分析燃用这2种燃料时HC和CO的排放特性,以及发动机的转速特性。试验结果表明:在不改变发动机机构和控制的情况下,2种燃料对发动机转速特性的影响区别不大,但使用丁醇汽油混合燃料发动机HC和CO的排放低于汽油。
根據相關規程要求,對-7℃時的髮動機冷起動特性進行試驗。選用汽油和體積分數為20%的丁醇汽油混閤燃料進行對比研究,分析燃用這2種燃料時HC和CO的排放特性,以及髮動機的轉速特性。試驗結果錶明:在不改變髮動機機構和控製的情況下,2種燃料對髮動機轉速特性的影響區彆不大,但使用丁醇汽油混閤燃料髮動機HC和CO的排放低于汽油。

According to the relevant regulations and requirements in this paper ,the cold‐start characteristics of the engine at -7 ℃ has been tested .Utilizing gasoline and butanol gasoline blended fuel at a volume fraction of 20% separately in the contrast experiment ,analyzed mainly the emission characteristics and engine speed characteristics of HC and CO when the two kinds of fuel are used respectively . The experimental results show that :The effect of the two kinds of fuel on engine speed characteristics is little different in the case of not changing the engine mechanism and control ,but when fuel the engine with butanol gasoline blended fuel ,emission characteristics of HC and CO is lower than gasoline’s .
