Abstract
The utility model relates to a supercharger exhaust interface device of an internal combustion engine, which consists of a flange (1) and an admission pipe (2). The air intake hole (4) of the flange (1) is connected with the inner hole (4) of the admission pipe (2) in a smooth way. The utility mode has a reasonable structure, and the air flow can flow uniformly after flowing out of the supercharger outlet, which correspondingly reduces the exhausting back pressure and the disturbance of the air flow between the air intake flange of the catalyst converter and the air intake end cone.
Description
Technical field
The utility model relates to the pressurized machine exhaust port device in the internal combustion engine exhaust system.
Background technique
The flange of the exhaust port device of supercharging gas and the Placement between the suction tude are that suction tude is inserted in the inlet hole of flange behind the segment distance, with both welding in the existing internal combustion engine exhaust system.The deficiency that Placement between existing this flange and the suction tude exists is: air-flow is when the suction port of flange enters, can directly impact the end or the weld joint of suction tude, cause herein that air-flow is inhomogeneous to flow, the mobile of air-flow is affected, and influences back pressure.
The model utility content
The purpose of this utility model is to provide a kind of internal-combustion engine booster exhaust port device, and the air current flow of being discharged to this exhaust port device by supercharger outlet is smooth and easy, and exhaust back pressure is little.
For achieving the above object, the utility model adopts following scheme: internal-combustion engine booster exhaust port device, it is joined by flange and suction tude and constitutes, the inlet hole of flange and the endoporus of suction tude is smooth joins.
By such scheme as seen, because the inlet hole of flange and smooth the joining of endoporus of suction tude, be achieved mobile in both connection part smoothnesses of the air-flow that enters the flange inlet hole, thereby reduce exhaust back pressure accordingly.
The utility model is rational in infrastructure, and it can make air-flow flow uniformly after supercharger outlet flows out, and reduces the flow perturbation between catalyst converter inlet flange and the inlet end awl.
Description of drawings
Accompanying drawing is the utility model one embodiment's a structural representation.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to accompanying drawing
The internal-combustion engine booster exhaust port device that the utility model provides, it is joined by flange 1 and suction tude 2 and constitutes, the inlet hole 4 of flange 1 and smooth the joining of endoporus of suction tude 2.Preferable Placement as shown in drawings between flange 1 and the suction tude 2: the edge at the rear end of flange 1 inlet hole 4 has counterbore 3, the front end of suction tude 2 stretches into counterbore 3 and joins with flange 1, counterbore 3 is coaxial with inlet hole 4, and the semidiameter that counterbore 3 and inlet hole are 4 equals the wall thickness of suction tude 2.After the front end of suction tude 2 stretched into counterbore 3,1 of suction tude 2 and flange were the outer shroud welding.
By accompanying drawing as seen, the utility model has been optimized the flange of internal-combustion engine booster exhaust port device and the Placement of suction tude, compares the existing Placement that adopts the blue inlet hole of suction tude direct insertion method, and the effect of air current flow is obviously improved.
Claims (4)
1, internal-combustion engine booster exhaust port device, it be is characterized in that: the inlet hole (4) of flange (1) and smooth the joining of endoporus of suction tude (2) by flange (1) and suction tude (2) formations of joining.
2, internal-combustion engine booster exhaust port device according to claim 1 is characterized in that: the edge at the rear end inlet hole (4) of flange (1) has counterbore (3), and the front end of suction tude (2) stretches into counterbore (3) and joins with flange (1).
3, internal-combustion engine booster exhaust port device according to claim 2, it is characterized in that: counterbore (3) is coaxial with inlet hole (4), and the semidiameter between counterbore (3) and inlet hole (4) equals the wall thickness of suction tude (2).
