Abstract
The utility model relates to an activated carbon absorption vacuum control type controller for fuel oil evaporation pollutant. Two tipping valves are catercorner installed at the top of a gasoline tank, and the vacuum signal a desorption valve is connected with the vacuum of an engine distributor block. A desorption port is connected with an engine PCV and the vacuum of a suction manifold. Activated carbon which has good adsorption and desorption performances is used for adsorption, and the vacuum of an intake system is used for desorption when the engine normally works. The pollution of evaporation pollutant of the fuel system of the gasoline automobiles to the ambient atmosphere can be basically eliminated, and simultaneously, the is energy saved. The controller has no harmful effect to the performance of the automobile, and can be applied to all gasoline automobiles.
Description
The utility model relates to a kind of active carbon adsorption vacuum control type fuel evaporation pollutant control gear.
The home-produced fuel car is owing to design the port (as the outer equalizing orifice on vent on the gas tank cap and the Carburetor) that straight-through atmosphere is arranged on the oil-fired system at present, oil-fired system can produce respiration by these atmosphere entrys when ambient temperature and variation in pressure, thereby gasoline vapor is discharged in the air, causes the direct waste of the energy and the severe contamination of ambient air.
The purpose of this utility model is the fuel evaporation pollutant control gear that a kind of active carbon adsorption vacuum control type will be provided, it can solve the contaminants environment of discharge vaporization in the gasoline car oil-fired system and the problem that wastes energy effectively under the situation that does not influence vehicle operation performance.
The purpose of this utility model is achieved in that
This device is made up of two Tipping valves (1), two two-way pressure-limit valve of diaphragm list spring type (2), a flat charcoal canister (3) and a desorption valve (4), wherein: Tipping valve (1) becomes diagonal to be installed in the petrol tank top, desorption valve (4) vacuum signal sending and receiving motivation distributor vacuum, desorption mouth sending and receiving motivation PCV valve and air-distributor vacuum.Two-way pressure-limit valve (2) is two diaphragm list spring types, and the restriction positive pressure is 3～5kPa, and the restriction negative pressure is 0～2kPa.Charcoal canister (3) is a flat upper port type, and amount of fill is 800～1200ml.Desorption valve (4) is a normal close type, and opening the vacuum difference is 3～8kPa.
The utlity model has following advantage:
Install two Tipping valves additional at the petrol tank top, this valve is drawn fuel tank with gasoline vapor on the one hand, stops liquid gasoline to flow out fuel tank when unexpected overturning of automobile or oiling overfill on the other hand; Pressure with gasoline vapor in the two-way pressure-limit valve control fuel tank; Adopt the storage facility of charcoal canister as gasoline vapor, packing in the charcoal canister has the active carbon of good adsorption properties and desorption performance, and charcoal canister is that flat is to improve the utilization ratio of active carbon; Utilize the vacuum of engine aspirating system that charcoal canister is carried out desorption; With the desorption valve control charcoal canister desorption moment and desorption gas flow, make the unlikely engine performance that influences of desorption air-flow, when automobile is in vehicle stop state, gasoline vapor in the petrol tank passes through Tipping valve, send in the charcoal canister after two-way pressure-limit valve pressure limiting and store, cleaned air passes enters in the air by the atmosphere entry of charcoal canister; When the automobile proper functioning, under vacuum action, ambient air sucks from the ventilating hole of charcoal canister, being stored in gasoline vapor in the active carbon sends into this air-flow in the suction tude of motor and burns, thereby make active carbon recover adsorptive power, for adsorptive process is next time prepared, this desorption process is by the control of desorption valve, so move in circles, the gasoline vapor that oil-fired system is evaporated obtains recycling, solved the pollution of evaporative pollutants, also saved the energy atmosphere environment.
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the active carbon adsorption vacuum control type fuel evaporation pollutant control gear schematic diagram that the utility model proposes
Fig. 2 is the active carbon adsorption vacuum control type fuel evaporation pollutant control gear schematic representation that the utility model proposes
Describe in detail according to the concrete device that the utility model proposes below in conjunction with Fig. 2:
This device comprises into two Tipping valves (1), a charcoal canister (3) that is connected the two-way valve (2) in the pipe, a storage gasoline vapor, the control desorption desorption valve (4) constantly that diagonal is arranged in the fuel tank end face, the mini three links (5) of desorption valve (4) number of winning the confidence, desorption mouth reducing tee (6) and full three links (7), ventilating glue tube (8), vacuum signal sebific duct (9).
The gasoline vapor that is evaporated from petrol tank goes out through the faller gill of Tipping valve (1), this steam is pushed two-way valve (2) open and is entered charcoal canister (3) and be stored in this, when the motor proper functioning, the vacuum of gas handling system is opened desorption valve (4) by vacuum signal sebific duct (9); Ambient air is under the effect of PCV valve vacuum; suck from the atmosphere entry of charcoal canister (3); when flowing through charcoal canister (3); the gasoline vapor that is stored in the active carbon is brought in the suction tude and burns in motor with the air inlet mixed gas through desorption valve (4), reducing tee (6); no longer enter in the atmosphere, thereby realize energy saving and the purpose of protecting environment.
The joint of the utility model and automobile has only two places: two Tipping valves are installed at the petrol tank top, the desorption valve is got the gas handling system vacuum and is carried out desorption control, the mounting hole of Tipping valve has shaped when the fuel tank punching press, only need buckle into Tipping valve during installation, the desorption valve only need disconnect sebific duct between gasoline car distributor vacuum hose and PCV valve and intake manifold when installing, insert desorption valve vacuum signal mini three links respectively and the reducing tee of desorption mouth gets final product, remaining part only need look for a suitable space fixing just, so install simply especially, implement easily.
