主要对目前城市在用汽油车改装成液化石油汽／汽油两用燃料汽车所采用的机械式文立里管型混合器与发动机的匹配进行研究。应用了流体力学、燃烧热化学理论、混合器工作原理以及内燃机相关原理，推导出发动机与混合器、蒸发器结构性能参数的理论匹配关系式，建立起最终的理论匹配计算模型；并开发出一套简洁实用的基于ＷＩＮＤＯＷＳ操作平台之上的计算机理论模拟计算程序，并分别在ＣＡ６１０２、ＴＪ３７６Ｑ发动机上经过了试验验证，用于指导城市在用汽油车向液化石油汽人气油两用燃料清洁汽车的改装，实践证明效果良好。
Mainly on the city in the use of gasoline vehicles converted into liquefied petroleum gas / gasoline dual-fuel vehicles used by mechanical Wenli tube mixer and engine match. The theory of fluid mechanics, the theory of combustion thermochemistry, the working principle of the mixer and the related principle of the internal combustion engine are applied to deduce the theoretical matching relationship of the performance parameters of the engine, the mixer and the evaporator, and the final theoretical matching calculation model is established. The set of simple and practical computer simulation program based on the WINDOWS operating platform has been tested and verified on the CA6102 and TJ376Q engines, respectively, to guide the city to clean the automobile from gasoline vehicles using liquefied petroleum gas Modified, practice proved effective.
