[0078] In this way, when the heated air flows into the canister 1 and the heater 80 supplies heat to the activated carbon 50, the desorption performance of the fuel combustible gas adsorbed on the activated carbon 50 is higher than that of the first embodiment.
[0079] Therefore, the combustible fuel gas adsorbed on the activated carbon 50 can be desorbed and discharged in a shorter time.

The invention provides a canister provided with a heater, the problem to be solved is that: temperature generated when adsorption of combustible gas is removed has a limit, removal rate of adsorption of combustible gas is low, and requirement of hybrid power type vehicles can not be satisfied. The key points of the canister provided with a heater are in that: the upper part of the canister is provided with a connecting opening connecting a fuel box and a purifier, a main body is respectively a first space and a second space at the two sides of an isolation space, active carbons are filled in the first space and the second space, a heater capable of heating the active carbons is vertically inserted and installed in the isolation space. The beneficial effects of the canister provided with a heater are: the canister can provide heat for whole active carbons, thereby improving performance of removal rate of adsorption of combustible gas.
Description
technical field [0001] The invention relates to a canister for automobiles that can reduce tail gas emissions, that is, the combustible gas fuel adsorbed on the surface of activated carbon inside the canister can be more easily desorbed and flows into the canister of the engine. Background technique [0002] Generally speaking, a filter (canister) is used in automobiles, which is a device that filters the fuel combustible gas (hereinafter referred to as combustible gas) stored in the fuel tank and then re-transfers it to the engine. [0003] Generally, the fuel required to drive the engine is stored in the fuel tank. The fuel in the fuel tank vaporizes as the ambient temperature changes, thereby producing combustible gas. Since these combustible gases contain harmful components (HC, etc.), when these harmful components are discharged outside the vehicle, the air is polluted and fuel is wasted. [0004] When the engine stops working, the filter can use the internal activate...
