Embodiment 1
[0047] see figure 1 As shown, the embodiment of the present invention provides an air filter and canister integrated device, which includes a carbon powder filling chamber 1, an air clean chamber 2, and an air dirty chamber 3 arranged sequentially from top to bottom;
[0048] The side wall of the carbon powder filling chamber 1 is provided with a carbon canister adsorption port 10 and a carbon canister desorption port 11 communicating with the interior of the carbon powder filling chamber 1, and the interior of the carbon powder filling chamber 1 is filled with carbon powder;
[0049] The side wall of the air clean chamber 2 is provided with an air filter outlet 20 communicating with the interior of the air clean chamber 2;
[0050] The side wall of the dirty air chamber 3 is provided with an air filter inlet 30 communicating with the interior of the dirty air chamber 3; wherein,
[0051] The carbon powder filling chamber 1 communicates with the air clean chamber 2 through a ...
Embodiment 2
[0069] see figure 2 As shown, the embodiment of the present invention provides a method for using the air filter and canister integrated device based on Embodiment 1, the method includes steps:
[0070] When the vehicle is refueled, after the gasoline is injected into the fuel tank of the vehicle through the refueling gun, the fuel tank is connected to the adsorption port 10 of the carbon tank, and the mixed gas of air and HC pollutants passes through the carbon powder filling chamber 1, the perforated partition 4, and the carbon paper 40 , the filter element layer 5 and the air filter inlet 30 are discharged to the atmosphere;
[0071] When the vehicle is running and the engine is in working condition, the air filter air outlet 20 communicates with the engine, and the outside air passes through the air filter air inlet 30 and filters dust through the filter core layer 5, and then enters the engine through the air filter air outlet 20 to participate in the combustion process;...

Abstract
This application relates to an air filter and carbon canister integrated device and its use method, and relates to the field of automobile technology. The air filter and carbon canister integrated device includes a carbon powder filling chamber, an air clean chamber and an air dirty chamber arranged in sequence from top to bottom The side wall of the carbon powder filling chamber is provided with a carbon canister adsorption port and a carbon canister desorption port communicating with the inside of the carbon powder filling chamber, and the inside of the carbon powder filling chamber is filled with carbon powder; the air clean chamber The side wall of the air filter chamber is provided with an air filter outlet communicating with the inside of the air clean chamber; the side wall of the air dirty chamber is provided with an air filter inlet connected with the inside of the air dirty chamber. This application combines the air filter with the canister, so that it not only has the air purification function of the engine intake system, but also has the emission control function of the fuel system, so as to meet the functional requirements of the vehicle.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an integrated device for an air filter and a carbon canister and a method for using the same. Background technique [0002] With the rapid increase of the number of automobiles, there is a huge pressure on both energy and the environment, especially the HC pollutants emitted by automobile evaporation and the waste of energy. Therefore, it is necessary to control the evaporative emission of HC pollutants from automobiles. [0003] In related technologies, in order to control the evaporative emission of HC pollutants in automobiles, on the one hand, in the air filter parts of the air intake system, carbon paper with adsorption and desorption functions is welded to the inner wall surface of the clean end in the air filter , to reduce the emission of HC pollutants in the engine intake. On the one hand, it improves the adsorption and desorption capacity of the carbon tank for the...
