Abstract
The utility model discloses an engine exhaust manifold, including the body that is equipped with integral air intake flange face and the flange face of giving vent to anger, integral air intake flange face is equipped with locating hole, mounting hole and many exhaust passages, the flange face of giving vent to anger is equipped with the mounting hole, its characterized in that still be equipped with the uninstallation groove on the integral air intake flange face. The utility model discloses a set up the uninstallation groove on integral air intake flange face, the absorption is warp because the integral air intake flange face that thermal stress arouses, not only can avoid appearing gas leakage phenomenon, still can avoid warping because of integral air intake flange face and send the construction bolt crooked to make things convenient for exhaust manifold's normal dismantlement.
Description
Technical field
The utility model relates to automobile engine exhaust system, is specifically related to a kind of automobile engine to exhaust manifold.
Technical background
The available engine gas exhaust manifold comprises the body that is provided with the integrated type inlet flange face and the flanged surface of giving vent to anger; Wherein, the integrated type inlet flange face that is provided with many air outlet flues is communicated with (quantity of air outlet flue identical with the quantity of exhaust branch pipe and corresponding the connection) one by one with a plurality of exhaust branch pipes.After the waste gas that removes from inblock cylinder converged in body through exhaust branch pipe, air outlet flue successively, flange flowed into the vent systems cold junction through giving vent to anger.Along with the requirement to engine performance and oil consumption improves constantly; The delivery temperature of motor is also increasingly high; Cause this integrated type inlet flange face under high temperature is easy, to deform, and then cause gas leakage, also can can't dismantle gas exhaust manifold when serious because of construction bolt is squeezed to bend.
Summary of the invention
The purpose of the utility model provide a kind of simple in structure, integrated type inlet flange face can be because of the enmgine exhaust of high temperature deformation.
The utility model is achieved in that a kind of enmgine exhaust; Comprise the body that is provided with the integrated type inlet flange face and the flanged surface of giving vent to anger; Said integrated type inlet flange face is provided with positioning hole, mounting hole and many air outlet flues; The said flanged surface of giving vent to anger is provided with mounting hole, it is characterized in that also being provided with spron on the said integrated type inlet flange face.
Said spron is between two adjacent air outlet flues.
The dual-side edge of said integrated type inlet flange face is the inclined-plane.
The angle of said inclined-plane and integrated type inlet flange face is 20 °.
The utility model is through being provided with spron on integrated type inlet flange face; Absorb because the integrated type inlet flange facial disfigurement that thermal stress causes; Not only can avoid the phenomenon that leaks air; Also can avoid because of integrated type inlet flange facial disfigurement causes the construction bolt bending, thus the normal dismounting of easy to exhaust manifold.The dual-side of integrated type inlet flange face can increase the impacting force of integrated type inlet flange face along being set to the inclined-plane, with the risk of further reduction integrated type inlet flange face gas leakage, can alleviate the weight of enmgine exhaust simultaneously, saves material.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A of Fig. 1 is to schematic representation.
Among the figure: 1-integrated type inlet flange face (11-positioning hole, 12-mounting hole, 13-air outlet flue, 131-first air outlet flue, 132-second air outlet flue, 133-the 3rd air outlet flue, 134-the 4th air outlet flue, 14-spron, 15-side along), 2-give vent to anger flanged surface, 3-body.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment:
Embodiment: shown in Figure 1 is a kind of four cylinder engine gas exhaust manifold; Body 3 is provided with integrated type inlet flange face 1 and gives vent to anger flanged surface 2; Said integrated type inlet flange face 1 is provided with two positioning holes 11, ten mounting holes 12 and four air outlet flues 13, and the flanged surface 2 of giving vent to anger is provided with three mounting holes 21, also is provided with two sprons 14 on the said integrated type inlet flange face 1; Lay respectively between first air outlet flue 131 and second air outlet flue 132 and between the 3rd air outlet flue 133 and the 4th air outlet flue 134; The width of spron 14 is 5mm, and the dual-side of integrated type inlet flange face 1 is along being inclined-plane 15, and said inclined-plane 15 is 20 ° with the angle a of integrated type inlet flange face 1.
Enmgine exhaust for other cylinder number; The quantity of spron 14 can be carried out corresponding setting according to the quantity of cylinder; For example; For the six cylinder engine gas exhaust manifold, can get final product increasing by two sprons again between second air outlet flue and the 3rd air outlet flue and between the 4th air outlet flue and the 5th air outlet flue.
Owing to expand to two ends after gas exhaust manifold is heated, under identical thermal stress, the thermal distortion at gas exhaust manifold two ends is maximum, therefore, between two air outlet flues in the middle of the integrated type inlet flange face, can not establish spron usually.
