摘 要: | 以一台1.5L、直列、四缸、四冲程发动机为基础开发了甲醇-汽油两用燃料发动机,对原发动机的硬件和软件进行了局部修改,选择了比较容易实现的双油箱双油轨结构,设计了甲醇-汽油两用的燃油供给系统、点火系统以及控制软件,实现了发动机汽油起动、暖机,甲醇、汽油之间的自由切换以及甲醇、汽油单独燃烧等功能。对甲醇-汽油两用燃料发动机进行了试验研究,试验表明,在转速变化较大而负荷相对变化较小的工况下适合燃用甲醇。虽然甲醇的消耗量大约是汽油的2倍,但其燃烧热效率比汽油高。

Design of Petrol-methanol Dual-fuel Engine |

Abstract: | A petrol-methanol dual-fuel engine was developed by locally modifying the hardware and software of a 1 .5 L inline 4-cylinder and 4-stroke engine .The dual fuel tank and rail which could be realized easily were chosen ,the fuel supply system , ignition system and control software for petrol-methanol dual-fuel were designed ,and the starting and warming up functions of petrol and the free switch and respective combustion for methanol and petrol were realized .The experiments of the dual-fuel engine show that methanol is more appropriate for transient conditions with large speed and load variance .Although the con-sumption of methanol is twice of the petrol ,the thermal efficiency of methanol is higher than that of petrol . |
