The utility model provides an automobile engine exhaust manifold with a Y-shaped connecting structure, which comprises at least four stainless steel tube type air passages, i.e. a first air passage, a second passage, a third passage and a fourth passage, wherein overlapped exhaust does not happen between the first air passage and the second air passage and between the third air passage and the fourth air passage. The automobile engine exhaust manifold is characterized in that the outlet ends of the first air passage and the second air passage are connected with a first Y-shaped structure; the third air passage and the fourth air passage are connected with a second Y-shaped structure; the outlet ends of the first Y-shaped structure and the second Y-shaped structure are connected together by a constriction structure and expanded then by a horn-shape structure. The automobile engine exhaust manifold with a Y-shaped connecting structure has the following advantages: various air passage interferences of the engine are decreased, and uniform distribution of air flow on the surface of the catalyst is guaranteed so as to improve the transformation efficiency of the manifold catalytic converter.
Description
Technical field
The utility model relates to a kind of automobile engine to exhaust manifold.
Background technique
Each air flue of existing car engine machine cast pig gas exhaust manifold is interconnected together after becoming greatly gradually.Such structure helps air-flow velocity and slows down gradually, and it is more even to distribute simultaneously, with and eliminate the be evenly distributed gender gap of each air flue behind the carrier surface.But also there is phase mutual interference between each air flue simultaneously in such structure, the problem of the power that influence is started.Simultaneously, the heat management performance of cast iron structure is bad, in the engine start stage, can absorb more heat, thereby reduces the temperature of exhaust, is unfavorable for the ignition of catalyzer and increases discharging.And the weight of cast iron manifold also can impact for the light-weight design of car load.So for more and more stricter environmental regulation, improve the independence of each air flue and improve the power and the moment of torsion of motor, the heat loss when reducing engine start, weight reduction will be the inexorable trend of manifold development.
Summary of the invention
The purpose of this utility model provides a kind of automobile engine to exhaust manifold that improves fluid property.
In order to achieve the above object, the technical solution of the utility model has provided a kind of automobile engine to exhaust manifold of Y type linkage structure, comprise at least four air flues, i.e. first air flue, second air flue, the 3rd air flue and the 4th air flue, wherein, no exhaust is overlapping between first air flue and second air flue and between the 3rd air flue and the 4th air flue, first air flue, second air flue, the entrance point of the 3rd air flue and the 4th air flue connects inlet flange, it is characterized in that: the outlet end of first air flue and second air flue connects one the one Y shape structure, the 3rd air flue and the 4th air flue connect one the 2nd Y shape structure, the outlet end of the one Y shape structure and the 2nd Y shape structure links together by necked configuration, thereafter by a horn-type structure expansion.
Further, on described necked configuration, be provided with lambda sensor.
Described air flue, inlet flange, a Y shape structure, the 2nd Y shape structure, necked configuration, horn-type structure and lambda sensor adopt the stainless steel manufacturing
The utility model has the advantages that: by y-type structure, kept the independence of air flue, reduced the interference of each air flue of motor, and guaranteed the even distribution of air-flow, thereby improved the manifold conversion efficiency of catalytic converter at catalyst surface.By adopting the structure of Stainless Steel Tube, this will reduce the loss of heat, and the light-off time of accelerator activator helps to satisfy stricter emission request.Guaranteed that lambda sensor can access signal accurately, given engine management system, regulated the initial ejection that injection system reduces motor, be more conducive to the protection of environment thereby feed back correct information.

Embodiment
For the utility model is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figures 1 and 2, the automobile engine to exhaust manifold of a kind of Y type linkage structure that provides for the utility model, comprise four air flues, i.e. first air flue 5, second air flue 6, the 3rd air flue 7 and the 4th air flue 8, wherein, no exhaust is overlapping between first air flue 5 and second air flue 6 and between the 3rd air flue 7 and the 4th air flue 8, first air flue 5, second air flue 6, the entrance point of the 3rd air flue 7 and the 4th air flue 8 connects inlet flange, the outlet end of first air flue 5 and second air flue 6 connects one the one Y shape structure 9-1, the 3rd air flue 7 and the 4th air flue 8 connect one the 2nd Y shape structure 9-2, the outlet end of the one Y shape structure 9-1 and the 2nd Y shape structure 9-2 links together by necked configuration 12, by a horn-type structure 11 expansions, on necked configuration 12 be provided with lambda sensor 10 thereafter.Air flue, inlet flange, a Y shape structure 9-1, the 2nd Y shape structure 9-2, necked configuration 12, horn-type structure 11 and lambda sensor 10 adopt the stainless steel manufacturing.
A Y shape structure 9-1 of the present utility model, the 2nd Y shape structure 9-2, necked configuration 12 and horn strucutre 11 have been avoided the interference between first air flue 5 and the 3rd air flue 7 and second air flue 6 and the 4th air flue 8.Simultaneously, the fluid that makes by necked configuration 12 and horn strucutre 11 is more evenly distributed carrier surface, and this has just guaranteed the power character of motor, also helps improving simultaneously the discharge efficiency of catalyzer.
Simultaneously, first air flue 5 and the 3rd air flue 7 and second air flue 6 and the 4th air flue 8 enter a Y shape structure 9-1 and the 2nd Y shape structure 9-2 respectively, can effectively keep the length unanimity of air flue like this, also avoid the interference between each air flue simultaneously.
Lambda sensor 10 is arranged in necked configuration 12 positions; can effectively must monitor the fluid composition information of each air flue, can give engine management system correct feedback, by regulating motor oil spout structure; reduce the original discharging of motor, more help environmental protection.
