甲醇汽油双燃料系统汽车(英文)

Gasoline-Methanol Dual-Fuel System Used in Trucks

本文从实用角度对点燃式汽车发动机燃用不同比例甲醇(M_x),直至纯甲醇(M_(100))进行了多方案的试验研究。根据我国目前供油网现状是及各地甲醇供应情况的不同,汽车司机一般都具有一定调整、维修的知识和技能。双燃料系统既可避免混溶、冷起动、热汽阻、加速性不灵敏等难题,又可节省改造加油站需要的庞大经费开支和助溶剂成本。因此我们的结论是:在石油燃料向醇类燃料过渡时期,以双燃料系统为基本形式来改进汽车对醇类燃料的适应性为最佳方案。

Many ways to use different proportions of methanol in spark ignitiongasoline engine CA-15 were tried.It was found that dual-fuel system is aneasy way which is free from difficulties characterized by gasoline-methanolblend system,for example,bad cold start,demixing after a period of store,slow warming-up,etc.With dual-fuel system,expense for new fuel supplynetwork and for cosolvent may be saved.So,during the period from usinggasoline now to using alcohol fuel extensively in the future,the dual-fuel system seems the most reasonable way of utilizing methanol in gasolinetrucks.
