Gas manifold.
In order to solve the above-mentioned technical problem, present invention employs following technical scheme：
A kind of enmgine exhaust, including exhaust main, and the multiple exhaust branch pipes being connected on the exhaust main, institute
The end for stating exhaust branch pipe has the flange portion for being used for being connected with engine cylinder block；Characterized in that, two institutes of arbitrary neighborhood
Stating between the flange portion of exhaust branch pipe has spaced partitioning slot；It is respectively provided with and encloses in the flange portion of each exhaust branch pipe
The bolt hole that exhaust branch pipe is triangularly arranged around place.
Using said structure, the flange portion of two neighboring exhaust branch pipe is arranged at intervals, and around each exhaust branch pipe
Bolt hole is arranged triangular in shapely.So, because the flange portion of each exhaust branch pipe is is independently arranged so that each flange portion by
After thermal deformation, the flange portion on other exhaust manifolds is not interfered with, so as to reduce the deformation of each independent flange portion,
It can prevent from expanding with heat and contract with cold deformation and causing engine gas leakage, adaptability is preferable, is advantageous to improve engine overall performance.And
And using the bolt hole being triangularly arranged around exhaust branch pipe, single three-point fix can be carried out to flange portion, compared to more
Bolt positioning, flange portion buckling deformation can be avoided, the cooperation for enabling flange portion even closer covers in cylinder.
Further, the flange portion of the exhaust branch pipe is integrally triangular in shape, and the bolt hole is located at the flange respectively
At the triangle in portion.
So, it is possible to reduce the material of flange portion, reduce the weight of exhaust manifold, not only improve the light weight for realizing vehicle
Change, production can be saved again originally.
Further, the direction of the flange portion of each exhaust branch pipe is consistent, and a bolt hole in flange portion
It is located at the both sides of the exhaust main respectively with two other bolt hole；The flange portion of two exhaust branch pipes of arbitrary neighborhood it
Between the bolt hole flange portion that is arranged on the two neighboring exhaust branch pipe partitioning slot on, be two exhaust branch pipes method
The shared bolt hole in blue portion.
Using said structure, by flange portion towards consistent arrangement, while set and share between two neighboring flange portion
Bolt hole, the quantity of bolt hole can be reduced on the premise of the installation seal request of flange portion is ensured, be advantageous to improve dress
The efficiency matched somebody with somebody.
Further, the bolt hole is arranged in the both sides of the exhaust main；Also it is separately positioned on including two
The pressing plate of the exhaust main both sides, has on the pressing plate and the one-to-one bolt hole of all bolts hole positioned at homonymy.
So, when mounted, the bolt hole of every side is fastened by pressing plate, you can to realize traditional Integral flange
The sealing effectiveness in portion, there is the defects of can overcoming traditional Integral flange portion, to expand with heat and contract with cold deformation adaptability it is good, be not easy because
Expand with heat and contract with cold and deform and cause engine gas leakage, be advantageous to improve engine overall performance.
Further, the width of the partitioning slot is 3~5mm.
Further, the exhaust main and exhaust branch pipe are made using high-nickel austenite nodular cast iron material.
Further, the exhaust end of the exhaust main is provided with outlet flange triangular in shape.
Further, the exhaust branch pipe is provided with three, and the length of the exhaust branch pipe is 130~160mm, and caliber is
28~30mm.
In summary, the present invention is adaptable preferably, can prevent from expanding with heat and contract with cold deformation and causing engine gas leakage, have
The advantages that beneficial to engine overall performance is improved.
