During internal combustion engine; Cyclone device makes the mixture of air, dust and moisture in the admission line become by straight line motion through this device back and rotatablely moves; Because dust and moisture granular mass are bigger, utilize the inertial separation principle to let dust and moisture particle get into the dust discharge rhone, outside dust discharge rhone device discharge tube along the tube wall of admission line; Thereby to getting into the air purification of air-strainer; Protect filter core simultaneously, reach and surpass the air of internal-combustion engine required cleaning, drying, eliminated the infringement that makes internal-combustion engine premature wear, scuffing of cylinder bore owing to dust, moisture content.
Improve the turbidity test and the degree of dryness of the gas that gets into air-strainer, the present invention has designed mixture separation, the discharger of dust and moisture in the good air of a kind of simple in structure, low cost of manufacture, functional reliability.
Apparatus of the present invention technique effect is embodied in the following aspects:
1. this apparatus structure is simple, easy to manufacture and cost is low, through in the admission line of air-strainer inlet end, installing cyclonic separation, discharger additional and to admission line length dimension design adjustment, can realizing exchanging at fit on intrinsic suction tude.
2. this device can effectively come out dust in the mixture of flow air, dust and moisture in the admission line and moisture particle separation; Improve the air cleanliness and the degree of dryness that get into air-strainer, eliminated the infringement that makes internal-combustion engine premature wear, scuffing of cylinder bore owing to dust, moisture content simultaneously.
3. before this device is assemblied in the induction system of internal combustion engine air-strainer; Air, dust and the moisture that gets into air-strainer is carried out just separating; Improve to get into the gas turbidity test of air-strainer, thereby improve the working life of air-strainer and internal-combustion engine and give full play to the power character and the fuel economy of internal-combustion engine.
4. this device can also be generalized to the industry beyond the automobile according to the extensive use of internal-combustion engine, like engineering machinery etc.
