Abstract
An exhaust manifold comprises a first branch, an air inlet flange, a main body, a welding nut, an insulation cover, a central port, a second branch, an air outlet flange, a ceramic honeycomb and a honeycomb shell, wherein the front end of the first branch is connected with the air inlet flange, the rear end of the first branch is connected with the main body, the upper end of one side of the main body is fixedly provided with the welding nut, the upper side of the middle part of the main body is provided with the insulation cover, the central port is arranged on one side of the main body and on the opposite side of the welding nut, and the second branch is arranged on one side of the central port. The exhaust manifold has beneficial effects that the exhaust manifold is provided with the ceramic honeycomb and the honeycomb shell, so that the resistance force inside the main body is reduced, and the mutual interference is large; and a gasket is arranged between the main body and the insulation cover, so that the buffering space is achieved, and the structure of a product is more firm.
Description
Technical field
The present invention relates to a kind of discharge manifold, especially relate to a kind of discharge manifold of automobile engine exhaust system.
Background technique
Discharge manifold links to each other with engine cylinder, the exhaust of each cylinder is put together lead people's exhaust manifold, has the pipeline of difference.During the exhaust undue concentration, can produce the phase mutual interference between each cylinder, during certain cylinder exhaust just, just in time meet other cylinder and scurry the next waste gas that does not have emptying.Like this, will increase the resistance of exhaust, and then reduce the output power of motor.The way that solves is to make the exhaust of each cylinder separate branch of every cylinder, perhaps branch of two cylinders as far as possible.Existing discharge manifold is bigger at the body interior resistance mostly, and phase mutual interference between each cylinder.
Summary of the invention
Technical problem to be solved by this invention is to provide the discharge manifold that a kind of internal drag is less, the phase mutual interference is little.
A kind of discharge manifold; Comprise first arm, inlet flange, main body, welded nut, thermal shield, hub-interface, second arm, the flange of giving vent to anger, ceramic honeycomb and honeycomb shell; The described first arm front end is connected with inlet flange, and the first arm rear end is connected with main body, and main body one side upper end is fixed with welded nut; Main body middle part upside is provided with thermal shield; Hub-interface is located at main body one upper lateral part and is in the opposite side of welded nut, and second arm is located at main body one side and is in the opposite side of first arm, and the flange of giving vent to anger is located at second arm, one side and is in the opposite side of hub-interface; Ceramic honeycomb is located at body interior, and the ceramic honeycomb outside is provided with the honeycomb shell.
Preferably, described thermal shield is provided with some through holes.
Preferably, be provided with liner between described main body and the thermal shield.
The beneficial effect of a kind of discharge manifold of the present invention is:
1. be provided with ceramic honeycomb and honeycomb shell, the body interior resistance is reduced, the phase mutual interference is bigger;
2. between main body and thermal shield, be provided with liner, have buffer space, make the structure of product more firm.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model;
Fig. 2 is the side structure schematic representation of the utility model.
Embodiment
Be described further below in conjunction with embodiment and accompanying drawing structure the utility model.
Like Fig. 1, shown in 2; A kind of discharge manifold comprises first arm 1, inlet flange 2, main body 3, welded nut 4, thermal shield 5, hub-interface 6, second arm 7, the flange 8 of giving vent to anger, ceramic honeycomb 9 and honeycomb shell 10, and described first arm, 1 front end is connected with inlet flange 2; First arm, 1 rear end is connected with main body 3; Main body 3 one sides upper end is fixed with welded nut 4, and main body 3 middle part upsides are provided with thermal shield 5, and hub-interface 6 is located at main body 3 one upper lateral parts and is in the opposite side of welded nut 4; Second arm 7 is located at main body 3 one sides and is in the opposite side of first arm 1; The flange 8 of giving vent to anger is located at second arm, 7 one sides and is in the opposite side of hub-interface 6, and ceramic honeycomb 9 is located at body interior, and ceramic honeycomb 9 outsides are provided with honeycomb shell 10.
Claims (3)
