Compact carbon canister assembly suitable for PHEV with long pure electric endurance

A compact carbon canister assembly suitable for a long pure electric endurance PHEV model relates to a carbon canister, and comprises a shell, a liquid collector, a cover plate, a stop valve and the like, first to fifth cavities are respectively arranged in the shell, the first to third cavities are filled with activated carbon with high adsorption capacity, and the fourth cavity is filled with activated carbon with low adsorption capacity. The fifth cavity is divided into two carbon rod mounting cavities which are communicated with each other, and at least one of the two carbon rod mounting cavities is provided with a carbon rod; and the first to fifth cavities are sequentially communicated in a roundabout communication mode. The carbon rod mounting cavity is added to adapt to the method of adding the carbon rods to meet the evaporative emission requirement of a long pure electric endurance PHEV model, hydrocarbon in mixed airflow can be fully adsorbed and purified through the roundabout design of the airflo
