The stiffening ring of above-mentioned cup inner bag outer side wall setting is positioned at the middle part of described cup inner bag outer side wall.
The rim of a cup portion of above-mentioned cup inner bag is provided with step in madial wall ring week, is equipped with the pressing plate of band through hole on this step.
Be provided with the support level that the stiffening ring with described cup inner bag outer side wall is complementary the madial wall ring week of above-mentioned cup, the stiffening ring of described cup inner bag outer side wall places on this support level, after contacting with the stiffening ring bottom surface, this step forms sealing, make the oily vapour of evaporation directly not enter down the gas flow cavity from last gas flow chamber, and must be through active carbon adsorption.
Above-mentioned bowl cover is provided with drain opening, and this drain opening is used in time discharging the water liquid that enters in the charcoal cup.
The internal diameter of above-mentioned atmospheric air port is 1.5～2 times of described motor interface internal diameter; The internal diameter of described motor interface is 1.5～3 times of described fuel tank interface internal diameter, and after being provided with like this, motor can not form solar or lunar halo in running, eliminated abnormal sound.
Above-mentioned cup inner bag is equipped with foam sponge with the cavity inner wall that described pressing plate surrounds, and this foam sponge plays a transition role and prevents that activated carbon granule from bleeding in the cup.
The utility model is owing to adopt the built-in cup inner bag of cup double layer construction; the gas flow chamber of oily vapour mixture between cup and cup inner bag of evaporation entered in the chamber of cup inner bag; and through getting back to engine cylinder combustion behind activated carbon granule absorption and the desorption; it adsorbs and the desorption area is big, ability is strong; not only made full use of active carbon, and can also the guard ring border, energy saving.
