摘要
自动加浓阀主要由PTC加热片、热感应器和阀针组成,它的主要作用是当发动机起动时要求化油器供给较浓的混合气,当发动机工作后则要求混合气逐渐变稀,最后停止供油。其中石蜡的配方、不同居里点的PTC加热片是影响加浓阀升程规律的主要因素。
The enriching valve composed of PTC heating plate, thermoinductor and valve needle serves as letting the carburetor provide enriched mixture when engine starts and letting the mixture gradually get leaner and stopping fuel delivery at last. The formula of wax and PTC heating plates at different Curie points are the main factors influencing the enriching valve lift.
