Abstract
An exhaust manifold comprises a first branch pipe, a second branch pipe, a third branch pipe, a fourth branch pipe, a fifth branch pipe, an air inlet flange, an air outlet flange, a ceramic honeycomb, a honeycomb casing and a heat-insulating shield. The exhaust manifold provided by the utility model has the benefits that four air inlets matched with the first branch pipe, the second branch pipe, the third branch pipe and the fourth branch pipe are formed in the air inlet flange, and thus the internal and external pressure difference of the exhaust manifold during work is effectively reduced; due to the arrangement of the ceramic honeycomb and the honeycomb casing, the internal resistance of a main body is reduced and greater mutual interference is avoided; and a liner is arranged between the main body and the heat-insulating shield and a buffer space is provided, so that the structure of products is firmer.
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.The thermal diffusivity of discharge manifold is very important performance index, and the external and internal pressure difference of gas exhaust manifold has also directly influenced the working efficiency of gas exhaust manifold.
Summary of the invention
Technical problem to be solved by this invention is to provide the gas exhaust manifold that a kind of internal drag is less, the phase mutual interference is little.
A kind of discharge manifold; Comprise first arm, second arm, the 3rd arm, the 4th arm, the 5th arm, inlet flange, the flange of giving vent to anger, ceramic honeycomb, honeycomb shell and thermal shield; One end of said first arm, second arm, the 3rd arm and the 4th arm is fixed in inlet flange one side; The other end is fixed in ceramic honeycomb one side, and the honeycomb shell is located at the outside, ceramic honeycomb middle part, and ceramic honeycomb top is provided with thermal shield; The 5th arm one end is fixed in ceramic honeycomb one side and is in the opposite side of first arm, and the flange of giving vent to anger is fixed in the other end of the 5th arm through screw rod.
Preferably, be provided with liner between described honeycomb shell and the ceramic honeycomb.
Preferably, described thermal shield is provided with some radiation holes.
Preferably, described inlet flange is provided with and first arm, second arm, the 3rd arm, four supporting suction ports of the 4th arm.
The beneficial effect of a kind of discharge manifold of the present invention is:
1. inlet flange is provided with and first arm, second arm, the 3rd arm, four supporting suction ports of the 4th arm, and it is poor effectively to have reduced the external and internal pressure of gas exhaust manifold when work;
2. be provided with ceramic honeycomb and honeycomb shell, the body interior resistance is reduced, the phase mutual interference is bigger;
3. 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.
Embodiment
Be described further below in conjunction with embodiment and accompanying drawing structure the utility model.
