Abstract
The invention discloses an exhaust catalyst which comprises a catalyst shell. One end of the catalyst shell is communicated with an exhaust pipeline via a first shell-end cone, a first end of the first shell-end cone is connected with the catalyst shell and is coaxial with the catalyst shell, a second end of the first shell-end cone is connected with the exhaust pipeline, and the central axis of the second end of the first shell-end cone is deviated from the central axis of the catalyst shell. The exhaust catalyst has the advantages that the distance from the exhaust catalyst to a manifold of an engine can be guaranteed, the flowing smoothness of gas in the exhaust pipeline further can be guaranteed, the exhaust catalyst can be easily used by different types of vehicles and is simple in structure, the development cycle can be effectively shortened, and the development cost can be effectively reduced.
Description
Technical field
The present invention relates to technical field of automobile engine, refer to particularly it is a kind of exhaust catalyst converter that automobile exhaust pipeline is arranged in automobile chassis space that is applied in.
Background technique
In original automotive development, when the exhaust catalyst converter of automobile is arranged and the required distance of manifold less, therefore, exhaust catalyst converter has certain randomness in underfloor layout, and along with the issue of new emission standard, for better ignition, catalyst converter need to be tried one's best near manifold, shorten the construction cycle in order to reduce development cost simultaneously, catalyst converter and the manifold that need to meet between different automobile types are arranged equidistance requirement, to reach the discharge bulletin generalization requirement between different automobile types.
Due to the little external factor restriction of restriction and automotive floor panel space of exhaust catalyst converter and manifold distance, in the development process of automobile, greatly increase the difficulty that exhaust catalyst converter is arranged.
Summary of the invention
Object of the present invention is exactly the deficiency that will solve above-mentioned background technology, and a kind of simple in structure and easy to exhaust catalyst converter layout solution is provided.
Technological scheme of the present invention is: a kind of exhaust catalyst converter, it comprises catalyst converter housing, it is characterized in that: one end of catalyst converter housing is connected with exhaust duct by the first shell ends cone, described the first shell ends is bored the first end and the concentricity axle of catalyst converter housing that are connected with catalyst converter housing, and the central shaft that the first shell ends is bored the second end being connected with exhaust duct departs from the central shaft of catalyst converter housing.
In such scheme:
Enter the airflow direction of the second end and the airflow direction of exhaust duct is coaxial; Or enter the airflow direction of the second end and the airflow direction of exhaust duct has angle.
The other end of described catalyst converter housing is connected with exhaust duct by the first shell ends cone; Or the other end of described catalyst converter housing is connected with exhaust duct by the second shell ends cone, the second shell ends cone and the concentricity axle of catalyst converter housing.
In the present invention, the second shell ends cone is traditional shell ends cone.
According to actual needs, catalyst converter housing is connected with exhaust duct by the first shell ends cone, the first shell ends can be bored to the central shaft of the second end that is connected with exhaust duct and the certain angle of the central axle designs of catalyst converter housing, this angle can be determined by the distance of exhaust duct in reality and manifold, so just can not change under the prerequisite of catalyst converter housing size, at limited automobile chassis space arranging exhaust air pipeline, not only can guarantee the distance between exhaust catalyst converter and motor, , can also guarantee the smooth and easy of gas flow in exhaust duct, more easily accomplish general between different automobile types, a kind of simple in structure, and can effectively reduce the exhaust catalyst converter of construction cycle and cost.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the first shell ends cone schematic side view in the present invention;
Fig. 3 is the first shell ends cone stereogram in the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, be convenient to be well understood to the present invention, but they do not form restriction to the present invention.
A kind of exhaust catalyst converter described in figure, it comprises catalyst converter housing 1, one end of catalyst converter housing 1 is connected with exhaust duct 4 by the first shell ends cone 2, the first shell ends cone 2 first ends that are connected with catalyst converter housing 1 2.1 and the concentricity axle of catalyst converter housing 1, the central shaft of the first shell ends cone 2 the second ends 2.2 that are connected with exhaust duct 4 departs from the central shaft of catalyst converter housing 1, be that the central shaft of the second end 2.2 and the central shaft of catalyst converter housing 1 can design certain angle according to the distance between exhaust duct in reality 4 and motor, this angle has variability, accordingly, the airflow direction entering in airflow direction and the exhaust duct 4 of the second end 2.2 also has certain angle.
The other end of catalyst converter housing 1 can be connected with exhaust duct 4 by eccentric setting the first shell ends cone 2, also can connect with exhaust duct 4 by the second shell ends cone 3, and the second shell ends cone 3 be that traditional shell ends is bored, it and the concentricity axle of catalyst converter housing 1.In this example, the other end of catalyst converter housing 1 is connected with exhaust duct 4 by the second shell ends cone 3.
The present invention according to actual needs, catalyst converter housing 1 is connected with exhaust duct 4 by eccentric setting the first shell ends cone 2, so just can not change under the prerequisite of catalyst converter housing 1 size, at limited automobile chassis space arranging exhaust air pipeline 4, not only can guarantee the distance between exhaust catalyst converter and manifold, can also guarantee the smooth and easy of gas flow in exhaust duct, more easily accomplish general between different automobile types, be a kind of simple in structure, and can effectively reduce the exhaust catalyst converter of construction cycle and cost.
