膜片式国Ⅲ化油器脱附结构的研究

Research for Desorption Structure of the State Ⅲ Diaphragm Carburetor

简要介绍了燃油蒸发控制系统中膜片式国Ⅲ化油器的几种脱附结构。对各结构的通用技术方案,存在的优、缺点及各自适用范围进行了研究说明。在满足燃油蒸发排放国Ⅲ标准及保证其它各性能优良的前提下,我们应根据各类摩托车的车型结构及所选用化油器来选择最佳脱附结构。

This study briefly introduces several desorption structures of the state Ⅲ diaphragm carburetor of the fuel evaporation control system.It researches the general technology program of these structures,and illustrates their advantages and disadvantages and their respective scope of application.Under the premise of meeting the fuel evaporative emission standards of stateⅢ,and ensuring other good performances,we should select the best desorption structure according to various types of motorcycle vehicle structures and the carburetors used.
