The air filter comprises an air filter body and an oil-gas separation cavity, wherein the oil-gas separation cavity is positioned in a cavity of the cleaning end of the air filter body, an air inlet is formed in the bottom of the oil-gas separation cavity, and an air outlet is formed in an upper cover of the oil-gas separation cavity. The air filter can effectively separate liquid engine oil in an oil-gas mixture input by a crankcase ventilation system during low-pressure ventilation, prevents the liquid engine oil from polluting a filter element of the air filter, and ensures the performance of the filter element, thereby ensuring the engine performance and reducing engine oil consumption.
Description
Technical field
The utility model belongs to air-strainer technical field, relates to a kind of air-strainer of integrated gas oil separation structure.
Background technique
In the development and Design of minicar gas handling system, along with the difference of gas handling system air cleaner assy fixed position on car load, air-strainer outlet is also corresponding different from the Placement of engine air throttle.Different Placements according to air-strainer outlet from engine air throttle, the low voltage air exchanging of crankcase ventilation system has also been taked different connection schemes.
When air-strainer is fixed on car load vehicle body, between air-strainer outlet and engine air throttle, adopt the Placement of connection rubber tube, can provide linkage structure for crankcase ventilation system low voltage air exchanging at the correct position of connection rubber tube, this structure has proposed the requirement of oil resistance to connection rubber tube material.
When air-strainer is fixed on motor, between air-strainer outlet and engine air throttle, adopt the structure of O type seal ring or stuffing box gland to be directly connected, the linkage structure of crankcase ventilation system low voltage air exchanging cannot be provided between air-strainer outlet and engine air throttle.When motor uses mechanical throttle valve, can on throttle valve structure, directly provide the linkage structure of crankcase ventilation system low voltage air exchanging; When motor uses electronically controlled throttle valve, the mixed gas of discharging containing organic oil due to crankcase ventilation system affects electronically controlled throttle valve performance, the linkage structure of crankcase ventilation system low voltage air exchanging can not be directly provided on throttle valve structure, therefore can only on air filter cleaning end cavity, provide the linkage structure of the low voltage air exchanging of crankcase ventilation system.
Low voltage air exchanging for crankcase ventilation system is connected to the structure on air filter cleaning end cavity, during the operation of car load motor, when the air-fuel mixture gas of crankcase ventilation system low voltage air exchanging input enters into air-strainer cleaning end cavity, mixed gas cognition produces certain liquid machine oil in inside cavity and gathers, the filter core of liquid machine oil meeting contaminated air filter cleaner that these gather, cause the hydraulic performance decline of filter core, when serious, can affect performance and the consumption of lubricating oil of motor.
Summary of the invention
The technical problems to be solved in the utility model is to provide the liquid machine oil in a kind of fuel-air mixture of can be effective separated crankcase ventilation system low voltage air exchanging input, avoid the filter core of liquid oil pollution air-strainer, thereby guarantee the air-strainer of the integrated gas oil separation structure of engine performance.
In order to solve the problems of the technologies described above, the air-strainer of integrated gas oil separation structure of the present utility model comprises air-strainer main body, Oil-gas Separation cavity; Described oil-gas separation chamber body is positioned at the inside of air-strainer main body cleaning end cavity, and its bottom, with suction port, covers with air outlet on it.
Described Oil-gas Separation cavity adopts square sealed cavity structure, and Mould Machining is simple, and cost is low.
The volume of described Oil-gas Separation cavity is 0.12L～0.15L.
Through a large amount of stands and complete vehicle test, determine, when the volume of Oil-gas Separation cavity is 0.12L～0.15L, oil gas separation is best.
Air outlet useful area on described Oil-gas Separation cavity upper cover is at 150mm
2～200mm
2in scope.
Air outlet useful area is according to relevant with the pressure difference in air filter cleaning end cavity in separated cavity, and definite through a large amount of stands and complete vehicle test, the air outlet useful area on Oil-gas Separation cavity upper cover is at 150mm
2～200mm
2in the time of in scope, separated cavity internal pressure is metastable.
The utility model utilizes the inner integrated Oil-gas Separation cavity of air-strainer cleaning end, and liquid machine oil is separated from the fuel-air mixture of the low voltage air exchanging input of crankcase ventilation system.Gas after separation enters air-strainer cleaning end cavity through air outlet, Oil-gas Separation cavity top, along with clean air after filtering enters into motor, burns; Separated liquid machine oil is along the connecting tube return engine of the low voltage air exchanging of crankcase ventilation system.Liquid machine oil in the fuel-air mixture of can the be effective separated crankcase ventilation system low voltage air exchanging input of the utility model, avoid the filter core of liquid oil pollution air-strainer, guarantee the performance of filter core, thereby guaranteed engine performance, reduced consumption of lubricating oil.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the air filtering device structure schematic diagram of integrated gas oil separation structure of the present utility model.
Embodiment
As shown in Figure 1, the air-strainer of integrated gas oil separation structure of the present utility model comprises air-strainer main body 5, Oil-gas Separation cavity 2; Oil-gas Separation cavity 2 is wherein integrated in the inside of air-strainer main body 5 cleaning end cavitys, forms an independently Oil-gas Separation cavity configuration.The bottom of Oil-gas Separation cavity 2, with suction port 1, is sealed by upper cover 3, and air outlet 4 is positioned on the upper cover 3 of Oil-gas Separation cavity 2.Described Oil-gas Separation cavity adopts square sealed cavity structure.The volume of Oil-gas Separation cavity is 0.12L～0.15L.Air outlet useful area on Oil-gas Separation cavity upper cover is at 150mm
2～200mm
2in scope.
As shown in Figure 1, when the fuel-air mixture of the low voltage air exchanging input of crankcase ventilation system enters into Oil-gas Separation cavity 2 by suction port 1, reduction rapidly due to mixed gas flow velocity, liquid machine oil in mixed gas is separated gradually, and due to the change of the direction of gas, liquid machine oil aggregate and precipitate is in the bottom of Oil-gas Separation cavity 2.Gas after separation enters into the cleaning end of air-strainer by the air outlet 4 on upper cover 3, along with clean air after filtering enters into motor, burn; Be deposited in the liquid machine oil of Oil-gas Separation cavity 2 bottoms by suction port 1, finally by the low voltage air exchanging connecting pipeline return engine of crankcase ventilation system.
