Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in this utility model and the feature in embodiment can
To be mutually combined.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Referring to figs. 1 through shown in Fig. 5, according to the exhaust manifold of a kind of preferred implementation of this utility model, in having
The body 2 of cavity 1, and it is provided with air inlet 3 and air vent 4.Described air inlet 3 is the most multiple and corresponds respectively to electromotor
The exhaust valve of each cylinder, for receiving the waste gas discharged from multiple combustor.Such as, for convenience of description, at diagram aerofluxus discrimination
Guan Zhong, corresponding to inline four-cylinder engine, the air inlet 3 of this exhaust manifold is formed at four inlet flanges 7 (the i.e. first air inlet method
Blue 7a, the second inlet flange 7b, the 3rd inlet flange 7c and the 4th inlet flange 7d) on.Described air vent 4 can be one,
The waste gas that each cylinder collected in by cavity 1 is discharged is expelled in air or is delivered to turbocharger etc. and carries out profit again
With.
Normally, as a kind of complex-shaped parts, in exhaust manifold, each several part (body 2 and each flange) is permissible
Utilize the means such as casting one-body molded.In traditional understanding, for avoiding stress to concentrate, except the flange for connecting, aerofluxus discrimination
The each several part of pipe should uniform wall thickness.But which results in the connection crossover position appearance of aforementioned such as body 2 and exhaust flange
The problem being easily generated non-penetrating crack, to this end, this utility model originally by body 2 and air vent 4 place with this
The wall thickness of the connecting portion of the integrated exhaust flange of body 25 is set greater than the wall thickness of body 2.Thus, strengthen this mistake
Crossing the anti-fatigue ability at position, reduction occurs due to the excessive such as non-penetrating crack caused with certain vibration frequency of amplitude
Probability.
It can be seen that this utility model overcomes stress concentrates technology prejudice significant for exhaust manifold intensity effect,
Break the conventional design design of uniform wall thickness, have employed the technological means that people give up due to above-mentioned technology prejudice, at body
Portion 2 is provided with relatively thick wall thickness with the connecting portion of exhaust flange 5, and to solve, the easy appearance of prior art existence is non-passes through
The technical problem of wearing property crackle.
But, wall thickness variation can produce stress and concentrate with being difficult to avoid that, therefore, it should at body 2 and exhaust flange 5
Connecting portion arranges suitable wall thickness, is otherwise difficult to significantly improve the performance of exhaust manifold.A kind of the most real at this utility model
Executing in mode, body 2 is big 0.8mm～1.2mm of the wall thickness of body 2 compared with the wall thickness of the connecting portion of exhaust flange 5.Real
Trampling proof, this set can be prevented effectively from the appearance of non-penetrating crack.
Along with the development of technology, people start making full use of of the energy of attention burning Indoor Combustion generation.Such as, aerofluxus
The waste gas that manifold is discharged carries heat energy and kinetic energy and other available compositions, can be as incited somebody to action by waste gas recirculation (EGR)
The portion that electromotor is discharged is transmitted back to air intake branch, and is again introduced into cylinder together with incoming mixture.Thus can be in order to
By the CO 2 reduction ignition temperature in waste gas, thus reduce the growing amount of nitrogen oxides.To this end, can be on exhaust manifold
Arranging EGR interface 8, this EGR interface 8 is formed on EGR adpting flange 9 integrated with body 2.
As a part for electromotor, on exhaust manifold, the position of each several part should coordinate electromotor integral arrangement and vehicle portion
The integral layout of part and determine.Just as described above, EGR interface 8 for being transmitted back to inlet manifold by waste gas, and this inlet manifold
It is all connected in cylinder head with exhaust manifold, therefore, for the ease of the layout of exhaust gas recirculation circuit, so that EGR connects
The end face of flange 9 is perpendicular to the centrage of air inlet 4.The most in the shown embodiment, the end face of EGR adpting flange 9 and air inlet
The plane at the end face of flange 7 each place is parallel.
In arrangement, gas exhaust piping generally extends to the tailstock from body bottom, to this end, so that inlet flange 7
End face and exhaust flange 5 end face each place plane between there are 45 °～90 ° of angle α, this angle α is preferably 58 °.
Thus, it is possible to connect gas exhaust piping easily at exhaust flange 5.
In the shown embodiment, exhaust manifold be linearly provided with four have identical towards air inlet 4, each air inlet
4 can be correspondingly formed respectively at the first inlet flange 7a, the second inlet flange 7b, the 3rd inlet flange 7c, the 4th inlet flange
On 7d.Wherein, exhaust flange 5 may be located on the cross section between middle two air inlets 4, i.e. illustrates the second inlet flange 7b
And on the cross section between the 3rd inlet flange 7c.EGR adpting flange 9 may be located at two near end, the same side adjacent enter
On cross section between QI KOU 4, it is illustrated that EGR adpting flange 9 is arranged on the 3rd inlet flange 7c and the 4th air inlet method by embodiment
On cross section between blue 7d.It is understood that exhaust flange 5 described herein, EGR adpting flange 9 and each inlet flange 7
Relative position can be determined with the relative position of each air inlet 3 by air vent 4, EGR interface 8.
In this case, the side that body 2 deviates from air inlet 3 phase, between exhaust flange 5 and EGR adpting flange 9
Shape drastically change, easily produce bigger stress and concentrate.To this end, in this utility model one the most preferred embodiment
In, could be formed with reinforcement 10 between described exhaust flange 5 and described EGR adpting flange 9, this reinforcement 10 is from body 2
Outer surface extend, and its two ends are connected to exhaust flange 5 and EGR adpting flange 9.Thus, it is possible to alleviation blind enema
The drastically change of shape between blue 5 and EGR adpting flanges 9, to avoid producing bigger stress concentration, improves exhaust manifold
Intensity.
The delivery temperature of exhaust manifold is significant for the control of electromotor.At exhaust flange 5 and body 2
Connecting portion can arrange temperature sensor connecting hole 6, as shown in Figure 2.
On this basis, this utility model also provides for a kind of electromotor with above-mentioned exhaust manifold.Preferably, this starts
Machine can have turbocharger, and exhaust manifold can be connected to turbocharger, to utilize electromotor to arrange by exhaust flange 5
The exhaust energy gone out drives turbo driving, to produce plenum.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
