摘　　要：根据化油器起动加浓阀总成的起动油道供油特性和PTC加热片的温度特性,调整化油器蜡式起动加浓阀总成的起动柱塞组件突出尺寸,优化设计化油器的起动柱塞、起动油针和起动块本体,同时提出了低温起动平稳性的评价方法,从而改善了摩托车在不同气候环境下的低温平稳起动性能。According to the starting fuel supply characteristics of starting piston assembly and the temperature characteristics of PTC heating plate for carburetor,we adjust the projection dimension of starting piston assembly for the wax-type starter enriching valve of carburetor,design optimally starting piston,starting oil needle and starting part body,and provide an evaluation methodology of cold start performance.So the stability is improved for low temperature starting of motorcycle in various environments.
