摘要
在分析二甲醚(DME)物化特性的基础上,提出了燃用DME对供油系的特殊要求。详细介绍了既能保持DME处于液态,又能将DME泵送到高压喷油泵中的新型二甲醚钢瓶-热力泵。阐述了该热力泵的设计要求及试验研究的方法。
On the basis of analysis on physical and chemical characteristics of dimethyl ether （DME）, special requirements for fuel system of IC engines fueled with DME is given. A new type of DME tank - thermodynamic pump, which can not only keep DME to be fluid, but also feed DME into high-pressure fuel pump, is introduced in detail. The design requirements and test method of this thermodynamic pump are also discussed here.
