Abstract
The utility model discloses an exhaust manifold assembly for an automobile, which comprises branch pipes, and is characterized in that: the lower exhaust ends of the branch pipes are connected with a main pipe, and a first sensor mounting groove is arranged on the main pipe; and the tail end of the main pipe is connected with a reducing pipe, and a second senor mounting groove is arranged on the reducing pipe. The exhaust manifold assembly for the automobile has a simple structure and is convenient to manufacture, the distance between the branch pipes is wider, and the main pipe can not be cracked due to heat stress, and thus the service life of the whole exhaust manifold is prolonged.
Description
Technical field
The utility model relates to a kind of manifold, particularly automobile exhaust manifold assembly.
Background technique
Gas exhaust manifold is meant the exhaust of assembling each cylinder of motor and the parts of exhaust airstream being guided into outlet pipe.On a four cylinder engine, use four arms usually, one type arm is to be directly connected to house steward, and the arm of another kind of type is to be divided into two teams to be connected respectively to house steward.Last type is commonly referred to the 4-1 type, and the advantage of such gas exhaust manifold is, and is simple in structure, easily manufactured.Second type gas exhaust manifold is commonly referred to the 4-2-1 type, and such gas exhaust manifold advantage is that its exhaust efficiency is higher than the 4-1 gas exhaust manifold.Yet the interval between above-mentioned two kinds of gas exhaust manifold arms is narrow, causes house steward owing to cracking appears in thermal stress, and the whole service life of gas exhaust manifold shortens.
The model utility content
The purpose of this utility model is to provide a kind of simple in structure, easily manufactured in order to solve above-mentioned the deficiencies in the prior art, and can prevent that the gas exhaust manifold house steward from owing to cracking appears in thermal stress, prolonging the automobile exhaust manifold assembly of the whole service life of gas exhaust manifold.
To achieve these goals, the automobile exhaust manifold assembly that the utility model is designed comprises arm, it is characterized in that described arm exhaust lower end is connected with house steward; House steward is provided with the first sensor mounting groove, and house steward's end is connected with reducing pipe; Reducing pipe is provided with the second sensor mounting groove.Described tube opening is provided with first flange, and the reducing pipe port is provided with second flange.Described arm bends to " L " shape.
The automobile exhaust manifold assembly that the utility model obtains, simple in structure, easily manufactured, apart from broad, house steward can be owing to thermal stress ftracture between the arm, thereby has prolonged the whole service life of gas exhaust manifold.
Description of drawings
Fig. 1 is embodiment's a structural representation;
Fig. 2 is the rear view of Fig. 1.
Among the figure: arm 1, house steward 2, first sensor mounting groove 3, reducing pipe 4, the second sensor mounting groove 5, first flange 6, second flange 7, bolt 8.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment:
As shown in Figure 1 and Figure 2, the automobile exhaust manifold assembly that the utility model provides comprises arm 1, and described arm 1 exhaust lower end is connected with house steward 2; House steward 2 is provided with first sensor mounting groove 3, and house steward's 2 ends are connected with reducing pipe 4; Reducing pipe 4 is provided with the second sensor mounting groove 5.Described arm 1 port is provided with first flange 6, and reducing pipe 4 ports are provided with second flange, 7, the second flanges 7 and are provided with bolt 8, and arm 1 is connected with the automobile cylinder respectively by first flange 6, and reducing pipe 4 is connected on the automobile catalytic converter by bolt 8.Described arm 1 can bend to " L " shape.But sensor installation in the first sensor mounting groove 3 and the second sensor mounting groove 5.
