Embodiment
Core of the present utility model is to provide a kind of intake manifold, and the space that this intake manifold takies is less, and its intake efficiency is higher.Another core of the present utility model is to provide a kind of motor that comprises above-mentioned intake manifold.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 2, the intake manifold that the utility model embodiment provides comprises admission line and EGR exhaust piping 21, and admission line is used for passing into fresh air, and EGR exhaust piping 21 is for passing into EGR waste gas, and EGR exhaust piping 21 is connected with admission line.On the inwall of admission line, there is diversion section 22 and arc eddy current section 23, between diversion section 22 and arc eddy current section 23, there is the space of flowing through for mixed gas, this space is connected with pressure stabilizing cavity, and mixed gas refers to fresh air and the mixed gas of EGR waste gas.Along the water conservancy diversion direction of the end of diversion section 22, arc eddy current section 23 is relative with the end of diversion section 22.
When EGR waste gas flows into after admission line from EGR exhaust piping 21, EGR waste gas mixes with fresh air, mixed gas will contact with diversion section 22, and in the effect of diversion section 22 downstream to arc eddy current section 23 places, due to the structural feature of arc eddy current section 23, after mixed gas contacts with arc eddy current section 23, will produce eddy current at arc eddy current section 23 places, and then making EGR waste gas more even with mixing of fresh air, mixed gas will enter in pressure stabilizing cavity.
Known by foregoing description, the intake manifold that the utility model embodiment provides makes the mixing uniformity of EGR waste gas and fresh air higher by the diversion section 22 on admission line and arc eddy current section 23, now also just without extending mixed pipe line, also without EGR exhaust piping is inserted in feed channel.Obviously,, than the content of introducing in background technique, the space that the admission line that the utility model embodiment provides takies is less, and its intake efficiency is higher.
In order further to improve the mixing uniformity of EGR waste gas and air, the outlet side of EGR exhaust piping 21 can be communicated in the inlet end of admission line, so that have the gas mixing zone of the inlet end that is positioned at admission line in admission line.Close together between the gas mixing zone of this structure and the inlet end of admission line, can mix EGR waste gas as soon as possible with air, extend the incorporation time of EGR waste gas and air, and then reach aforementioned object with this.
Further, in technological scheme, the upper inner wall of EGR exhaust piping 21 is training wall, and the water conservancy diversion direction of the end of this training wall is reverse in the airintake direction of admission line.Upper inner wall herein refers to the inner wall section at the top that is vertically positioned at EGR exhaust piping 21, and the water conservancy diversion direction of the end of training wall is reverse in the airintake direction of admission line, mean that EGR waste gas will be with respect to air inversion under the effect of refluence wall.Understandably, this scheme makes EGR waste gas and fresh air produce adverse current effect by training wall, EGR waste gas is mixed more even with fresh air.
Find through experiment repeatedly, when the inwall of arc eddy current section 23 is set to 1/4 arc structure taking the end of diversion section 22 as the center of circle, the mixing uniformity between EGR waste gas and air has significant amplification.Certainly, the structure of the inwall of above-mentioned arc eddy current section 23 is only described from approximate trend, and this structure deviation within the specific limits all falls in protection domain of the present utility model.
Above-mentioned EGR exhaust piping 21 adopts welding or other modes to link together again after can manufacturing separately with admission line, in order to improve the structural strength of whole intake manifold, the EGR exhaust piping 21 that the utility model embodiment provides forms integral structure with admission line, be both one processing, can adopt particularly the technology such as casting, machining.In addition, the manufactured materials of whole intake manifold can be metal, plastics, rubber or pottery etc.
The utility model embodiment also provides a kind of motor, and this motor comprises intake manifold, and this intake manifold is the described intake manifold of above-mentioned arbitrary technological scheme.Because above-mentioned intake manifold has above-mentioned technique effect, the motor that comprises this intake manifold also should have corresponding technique effect, repeats no more herein.
Only by the mode of explanation, some example embodiment of the present utility model is described above, undoubtedly, for those of ordinary skill in the art, in the situation that not departing from spirit and scope of the present utility model, can revise described embodiment by various mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claim protection domain.
