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。
In this paper, a multi-plan experimental study was conducted on the ignition type automobile engine with different proportions of methanol (M_x) and pure methanol (M_ (100)) from a practical point of view. According to the current situation of China’s oil supply network and around the supply of methanol is different, the car drivers generally have some adjustment, maintenance of knowledge and skills. Dual fuel system can avoid miscibility, cold start, thermal resistance, acceleration and other issues such as insensitivity, but also save the gas stations need to transform the huge expenditure and cosolvent costs. Therefore, we conclude that in the transitional period from petroleum fuel to alcohol fuel, the dual fuel system is the basic form to improve the adaptability of motor vehicles to alcohol fuel as the best solution.
