Detailed Description
The invention will be further explained with reference to the drawings.
The invention discloses a gas mixer of an engine, which comprises a mixing pipe 1, wherein the mixing pipe 1 is inserted into an air inlet manifold 2 of the engine along the radial direction, the pipe wall of the mixing pipe 1 is provided with a plurality of gas nozzles 11, and the gas nozzles 11 are strip-shaped and extend along the axial direction of the mixing pipe 1.
Specifically, as shown in fig. 1, the axial direction of the mixing pipe 1 is perpendicular to the axial direction of the intake manifold 2, and the gas nozzles 11 are arranged in a strip shape extending along the axial direction of the mixing pipe 1, so that the gas ejected from the gas nozzles 11 forms a wind wall extending along the axial direction of the mixing pipe 1, and the flow direction of the air is along the axial direction of the intake manifold 2, so that the air directly contacts the wall surface of the wind wall formed by the gas, the contact area of the air and the wind wall is very large, and the high-quality mixed gas is obtained by being mixed sufficiently.
The gas mixer of the invention improves the conventional round hole shape of the gas nozzle 11 into a strip shape on the basis of the existing mixer, and greatly increases the contact area of the gas and the air on the premise of not changing the circulation area of the gas nozzle 11. And, through practical test, the gas mixing area of bar gas spout 11 is more than 2 times the gas mixing area of circular hole gas spout 11. Moreover, under the certain prerequisite of gas spout 11 flow area, the width of bar gas spout 11 is less, and the gas mixing area is big more, and its gas mixing area is higher than the multiple of circular port gas spout 11. In the practical application test of the gas mixer, the mixing area of the calculated strip-shaped holes is 2.6 times of that of the circular holes, so that the premixing efficiency of the mixing effect is greatly improved.
In one embodiment, the gas jets 11 extend continuously along the axial direction of the mixing tube 1, and a plurality of gas jets 11 are distributed along the circumferential direction of the mixing tube 1.
Specifically, the gas nozzles 11 in this embodiment extend continuously along the axial direction of the mixing pipe 1, as shown in fig. 1 to 3 of the drawings, that is, only one gas nozzle 11 is located at the same position in the circumferential direction of the pipe wall of the mixing pipe 1, and the air wall formed by the gas ejected from the gas nozzles 11 is also continuous.
Preferably, the gas jets 11 are wavy. The wavy gas spout 11 can increase the length of the gas spout 11 on the premise that the length of the mixing pipe is fixed, and then the mixed contact area of the ejected gas and the air can be further increased.
In one embodiment, the distance between adjacent peaks or adjacent troughs of the wavy gas jets 11 gradually increases from the midpoint of their length to the ends.
Specifically, as shown in fig. 1 to fig. 3 of the drawings, the wave-shaped gas nozzle 11 modified in the present embodiment has dense peaks and troughs and small wavelengths near the middle point of the length thereof, and sparse peaks and troughs and large wavelengths near both ends thereof, so that the flow area of the entire gas nozzle 11 along the axial direction of the mixing pipe 1 is not uniformly distributed.
The improvement is based on the non-uniform distribution of the air flow velocity in the intake manifold 2, and when air flows through the intake manifold 2, the air flow velocity near the central axis of the intake manifold 2 is high, and the air flow velocity near the wall of the intake manifold 2 is low, because the air flow velocity is reduced due to the frictional resistance with the wall of the intake manifold 2 during the air flow. The air flow rate and the air flow rate are in a proportional relation, so that as shown in figure 1, the air flow rate close to the central axis position of the air intake manifold 2 is large, and the air flow rate close to the pipe wall position of the air intake manifold 2 is small, so that the gas flow area of the gas nozzle 11 close to the middle point of the central axis position of the air intake manifold 2 is large, and the gas flow area of the gas nozzle corresponding to the pipe wall position of the air intake manifold 2 is small, so that the gas and the air in different regions are kept in a certain same proportion, and the mixing effect of the two gases is improved.
In one embodiment, the plurality of gas nozzles 11 form a plurality of nozzle groups distributed along the axial direction of the mixing pipe 1, and each nozzle group includes a plurality of gas nozzles 11 distributed along the circumferential direction of the mixing pipe 1.
Specifically, in this embodiment, the gas nozzles 11 are discontinuously distributed at the same position in the circumferential direction of the mixing pipe 1, there may be a plurality of gas nozzles 11 at the same position, and the plurality of gas nozzles 11 distributed circumferentially at a certain position in the axial direction of the mixing pipe 1 constitute a nozzle group.
In one embodiment, the distance between the adjacent nozzle groups increases along the center of the distribution position of the nozzle groups towards the outer side of the two ends.
Specifically, in this embodiment, the nozzle groups are densely distributed near the center of the distribution positions of the plurality of nozzle groups; the improvement that the groups of ports are sparsely distributed near the outer sides of both ends of the distribution position of the groups of ports is also to further optimize the distribution of the gas injection ports 11 with respect to the unevenness of the air flow velocity distribution in the intake manifold 2, and also to increase the output of the gas with respect to the large air flow rate near the axial position of the intake manifold 2.
In one embodiment, the number of the gas nozzles 11 in the nozzle groups in the direction toward the outer sides of both ends along the center of the distribution position of the plurality of nozzle groups is sequentially decreased.
Specifically, the improvement in the present embodiment is to further optimize the layout of the gas nozzles 11 by changing the number of the gas nozzles 11 in the nozzle groups at different positions, so as to optimize the density distribution of the gas nozzles at different positions, and finally adjust the flow area of the gas so as to adjust the output of the gas in different areas.
In one embodiment, one direction along the axis of the intake manifold 2 is an air intake direction, and the direction from the center inside the mixing pipe 1 through the gas nozzles 11 is a gas outlet direction, and the angle between the gas outlet direction and the air intake direction is not less than 30 ° and not more than 180 °.
Specifically, in the present embodiment, the distribution of the gas nozzles 11 in the circumferential direction of the mixing pipe 1 is further defined, and the range of the vector included angle between the gas outlet direction and the air inlet direction is represented on the structure of the mixing pipe 1, that is: the mixing pipe 1 is not provided with the gas nozzle 11 at the position back to the air inlet direction, which corresponds to the leftmost position of the cross section of the mixing pipe 1 shown in the attached figure 6. Because the air flow has an approximately parallel air inlet direction, as can be seen from fig. 6 of the drawings, the part of the mixing pipe 1 facing away from the air inlet direction is basically not in direct contact with the air due to the obstruction of the mixing pipe 1 itself; if the gas nozzle 11 is arranged on the part, the gas output through the gas nozzle 11 can not contact with the air in the first time, and meanwhile, the flowing direction of the gas is similar to the flowing direction of the air, so that the subsequent disturbance degree of the gas contacting with the air is small, and the mixing effect of the gas and the air can be further influenced.
It should be noted that, the mixing pipe 1 is not provided with the gas nozzles 11 except for the portion facing away from the air intake direction shown in fig. 6, and the plurality of gas nozzles 11 on the remaining portion are uniformly distributed, that is, the gas nozzles 11 are uniformly distributed in the circumferential direction in the distribution region.
In one embodiment, the cross-sectional shape of the mixing pipe 1 is an ellipse and the major axis direction of the ellipse is parallel to the axial direction of the intake manifold 2.
Specifically, the present embodiment improves the cross-sectional shape of the mixing pipe 1 such that the diameter thereof in the air flow direction is the largest (i.e., the major axis of the ellipse) and the diameter thereof in the direction perpendicular to the air flow direction is the smallest (i.e., the minor axis of the ellipse). This shape of the cross-section of the mixing tube 1 reduces the resistance of the mixing tube to the flow of the engine intake air, increases the area of the mixing tube 1 in the direction perpendicular to the flow of the air, provides a layout space for the gas nozzles 11, and provides the possibility of further improving the uniformity of the mixing of the gas and the air.
In one embodiment, the end of the mixing tube 1 within the intake manifold 2 is tapered.
In particular, in the present embodiment, the end of the mixing tube 1 is designed to be conical without a plug, which is based on the fact that less air flows from the vicinity of the end, and the gas flow rate to be provided in this area is also lower, so that it is not necessary to provide a cylindrical shape, and it is not necessary to provide a plug. Therefore, in the actual processing of the mixing tube 1, the tail end can be directly extruded into a cone shape or directly flattened, and the processing is convenient.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.

It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
