Abstract
The utility model provides an air cleaner with low resistance and high uniformity, and the air cleaner comprises an air inlet pipe, an air cleaner body assembly and an air outlet pipe, wherein the air cleaner body assembly comprises an inlet-side expansion chamber, a filter element and an outlet-side chamber. The air cleaner is characterized in that the connection position of the air inlet pipe and the inlet-side expansion chamber is far away from the filter element; and the internal face of the inlet-side expansion chamber is an inclined plane or a cambered surface in smooth connection. According to the air cleaner, since the connection position of the air inlet pipe and the inlet-side expansion chamber is changed and the step face structure of the inlet-side expansion chamber is optimized, the bench test confirmes that the intake resistance of the engine is reduced markedly, the charge efficiency of the engine is improved obviously, and related standard requirements can be met.
Description
Technical field
The utility model relates to a kind of air-strainer, relates in particular to the air inlet side structure of the air-strainer of a kind of lower resistance and high uniformity coefficient.
Background technique
Air-strainer is the vitals of engine aspirating system, and the dirt that mainly act as in the filtered air is husky, and the air quality that guarantees to get into cylinder makes motor have longer working life; Air gets into from suction tude, gets into then in the expansion chamber to expand, and after filter element filtering falls impurity, from the steam outlet pipe of outlet side, flows out, and finally gets into intake manifold through closure.Reasonable structural design can reduce the car load noise, reduces intake resistance, makes engine charge abundant, improves charging efficiency, thereby fuel oil is fully burnt to reduce oil consumption.
For traditional air-strainer, air directly by suction tude to air inlet side expansion chamber, through filter core, outlet side cavity, be incorporated in the cylinder through steam outlet pipe.Owing to do not consider the position and the cavity geometry of inlet duct and cavity; The link position of air inlet side expansion chamber and suction tude is close to filter core; Air-flow can't fully expand and just directly impact the filter core face behind the air entering air inlet side expansion chamber; Reduce the filter core face velocity uniformity, made the filter core unbalance stress, shortened filter element life; Produce eddy current behind another part airflow collision air inlet side expansion chamber internal face, cause intake resistance to increase, thereby make whole engine system air inlet not smooth, the engine air in-cylinder combustion is abundant inadequately, can't satisfy emission request.
Summary of the invention
The utility model provides the air-strainer of a kind of lower resistance and high uniformity coefficient, to reduce the direct impact of inlet stream to filter core, improves the airspeed uniformity of air inlet side expansion chamber inner filter core face, and reduces the collision of inlet stream to air inlet side expansion chamber internal face.
The technological scheme that the utility model adopts is:
The air-strainer of a kind of lower resistance and high uniformity coefficient; Comprise suction tude, air-strainer body assembly, steam outlet pipe; Air-strainer body assembly is divided into air inlet side expansion chamber, filter core and the side cavity of giving vent to anger, and the position that said suction tude is connected with air inlet side expansion chamber is arranged on away from the filter core place; The left side of suction tude and the distance b >=30mm between the filter core, the airflow direction of described suction tude is the subtend filter core not.Said air inlet side expansion chamber internal face is the inclined-plane or the cambered surface of smooth transition.
The utlity model has following advantage: on the one hand owing to changed the link position between suction tude and the air inlet side cavity; Reduced the direct impact of air-flow to filter core; And improved the airspeed uniformity of filter core face, made it stressed evenly, thereby prolonged the working life of filter core; Owing to the inclined-plane or the cambered surface that the step surface of air inlet side expansion chamber inwall are changed into smooth transition, reduce the generation of eddy current on the other hand, reduced the gas-flow resistance loss, improved the operational efficiency of motor; In addition, it is less that the utility model also has change, lower-cost advantage.

Fig. 3 is the structural representation of the said air-strainer of the utility model;
Fig. 4 is the partial sectional view of the said air-strainer of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation:
Like Fig. 3 and shown in Figure 4, the air-strainer of a kind of lower resistance and high uniformity coefficient comprises suction tude 1, air-strainer body assembly 2, steam outlet pipe 3, and said air-strainer body assembly 2 is divided into air inlet side expansion chamber 21, filter core 22 and the side cavity 23 of giving vent to anger.
For guaranteeing fully to expand after air-flow gets into expansion chamber; With existing; The position that is connected with air inlet side expansion chamber 21 like the suction tude 1 of Fig. 1, air-strainer shown in Figure 2 moves to Fig. 3, position shown in Figure 4; Be that the position that suction tude is connected with air inlet side expansion chamber is arranged on away from the filter core place distance b >=30mm between the left side of suction tude 1 and the filter core 22.
For inlet stream being guided to filter core 22; And reduce the eddy current that inlet stream produces in air inlet side expansion chamber 21; The stepped shape internal face 24 of the air inlet side expansion chamber 21 shown in Fig. 1, Fig. 2 is changed into the inclined-plane or the cambered surface internal face 25 of the smooth transition shown in Fig. 3, Fig. 4; Like this, reduce the generation of eddy current, reduced the intake resistance at suction port place.
The utility model is owing to changed the position that suction tude 1 is connected with air inlet side expansion chamber 21; Optimized the structure of the step surface 24 of air inlet side expansion chamber 21, confirmed that through platform experiment the intake resistance of motor significantly reduces; The motor charging efficiency obviously improves, and satisfies the relevant criterion requirement.
