Abstract
The utility model discloses a charcoal canister for gas filtration of a car and a motorcycle, which consists of a shell, a cover and built-in active carbon, wherein the bottom part of the shell is provided with an oil-gas inlet passage and an oil-gas recycling passage, and the upper and the lower parts of the active carbon are respectively provided with a filtering pore plate and a filter pad for limiting the active carbon, and an elastic element which is used for the limitation is arranged between the cover and the active carbon filter plate, and the cover is provided with an air balance passage and a gas outlet passage, thus effectively improving the exhaustion pollution of the motor vehicle and favoring the environmental protection.
Description
Technical field
The utility model relates to the fuel evaporation volatile matter treatment device that is used for gasoline car, is specially automobile, motorcycle filter gas charcoal canister.
Background technique
Along with the quickening that China's automobile enters family's paces, its motor vehicle emission pollutant environmental pollution is more and more serious.Solve the problem of motor vehicle emission pollutant, become each metropolitan hot issue urban air pollution.At present, discharging pollutants in automobile, the motorcycle just directly is discharged in the air, is badly in need of a kind of fuel evaporation treatment device that is used for gasoline car, improves the exhaust emission of Motor Vehicle.
The model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of automobile, motorcycle filter gas charcoal canister, can effectively improve the exhaust emission of Motor Vehicle.
For achieving the above object, be achieved by the following technical solution:
Automobile, motorcycle filter gas charcoal canister, form by housing, cap and built-in active carbon, it is characterized in that: housing bottom is provided with oil gas gas-entered passageway and oil gas recovery passage, the active carbon top and the bottom are provided with respectively and are used to limit orifice filter and the filter pad that active carbon is used, be provided with between cap and the activated carbon filtration plate and be used for spacing elastic element, cap is provided with air balance passage and outlet passageway.
Described filter pad, employing be nonwovens.
Fixing in aggregates between described housing and the cap by frictional vibration heat seal mode.
Oil gas on the described housing reclaims and is connected with air intake branch of the engine and fuel tank by vacuum hose with passage.
Described flexible pipe middle part has a solenoid valve or negative pressure control valve, the break-make of may command pipeline.
The external atmosphere of air balance passage on the described cap.
Adopt the charcoal canister of said structure, the oily vapour molecule of the activated carbon granule that is full of in the charcoal canister in can absorbing gasoline steam.Oil gas on the housing of charcoal canister reclaims and communicates with air intake branch of the engine by vacuum hose with passage 11, and the flexible pipe middle part has a solenoid valve or negative pressure control valve, the break-make of may command pipeline.When motor stops or during idle running, solenoid valve or negative pressure control valve are closed, when discharging pollutants in the fuel tank entered into jar by the gas-entered passageway on the housing 12, the oil gas molecule was attracted in the active carbon hole, prevented to discharge pollutants to enter atmosphere.When the motor proper functioning, solenoid valve or negative pressure control valve are opened, the gas handling system of motor sucks fresh air from the passage of the external atmosphere of charcoal jar, the petrol molecule that fresh air is taken away absorption in the active carbon simultaneously carries out secondary combustion to motor, thereby make the gasoline vapor of the interior absorption of this charcoal jar be able to recycling, do not enter in the atmosphere, reduced the exhaust emission of pollutant, help environmental protection.

Embodiment
As shown in Figure 1, 2, 3, automobile, motorcycle filter gas charcoal canister, form by housing 1, cap 2 and built-in active carbon 3, housing 1 bottom is provided with two passages 11,12, oil gas gas-entered passageway 12 is connected with fuel tank by rubber pipe, oil gas reclaims and is connected with Carburetor by flexible pipe with passage 11, and the flexible pipe middle part is connected to solenoid valve or negative pressure control valve, the effectively break-make of pilot line.Active carbon 3 top and the bottom are provided with filter pad 4 and the orifice filter 5 that is used to limit active carbon 3 usefulness respectively, what filter pad 4 adopted is nonwoven cloth material, be provided with between cap 2 and the activated carbon filtration web plate 5 and be used for spacing elastic element 6, fixing in aggregates between housing 1 and the cap 2 by frictional vibration heat seal mode, cap 2 is provided with outlet passageway 21,22, wherein air balance passage 21 leads directly to atmosphere, outlet passageway 22 is connected with intake manifold by flexible pipe in addition, can effectively reclaim part fuel evaporation volatile matter when the charcoal jar is saturated.
Adopt the charcoal canister of said structure, the petrol molecule of the activated carbon granule that is full of in the charcoal canister in can absorbing gasoline steam.Passage 11 on the housing 1 of charcoal canister communicates with air intake branch of the engine by vacuum hose, and the flexible pipe middle part has a solenoid valve or negative pressure control valve, the break-make of may command pipeline.When motor stops or during idle running, solenoid valve or negative pressure control valve are closed, when the gasoline vapor pollutant in the fuel tank entered into the charcoal jar by housing 1 upper channel 12, the oil gas molecule was attracted in the active carbon hole, prevented to discharge pollutants to enter atmosphere.When the motor proper functioning, solenoid valve or negative pressure control valve are opened, the gas handling system of motor sucks fresh air from the passage of the external atmosphere of charcoal jar, fresh air is taken away the petrol molecule through absorption in the active carbon simultaneously, thereby make the gasoline vapor of the interior absorption of this charcoal jar be able to recycling, do not enter in the atmosphere, effectively reduce the exhaust emission of pollutant, help environmental protection.
