[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0021] In the description of the present utility model, it should be noted that, unless otherwise specified, "multiple" means two or more; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] like Figure 1 and Figure 2 As shown, the exhaust head coke structure provided by the utility model, ( Figure 1 This is a single-side exhaust head coke mechanism. This device is applied to a six-cylinder engine. When installing, two pairs of exhaust pipes need to be set and connected to the three cylinder exhaust pipes on both sides of the engine respectively. However, since the working principles of both sides are the same, the structure of the other side will not be described in detail in this embodiment. The specific structure can be referred to Figure 2 . ) includes pipeline 1, pipeline 2, pipeline 3, pipeline 4, pipeline 5, pipeline 6 and valve 7. Pipeline 1 and pipeline 2 are both connected to one end of pipeline 3, and valve 7 is set between pipeline 2 and pipeline 3. Valve 7 is a pneumatic valve. Valve 7 is used to control the on-off between pipeline 2 and pipeline 3. By controlling the on-off of valve 7, the flux of airflow can be controlled, and then the power output of the car can be controlled. The other end of pipeline 3 is connected to pipeline 4, pipeline 5 and pipeline 6, and the path distances inside pipeline 4, pipeline 5 and pipeline 6 are the same. Due to the same path distance, the airflow in the three pipelines is uniform, which solves the problem of chaotic internal airflow, is resistant to high temperature and has fast heat dissipation, so that the power of the car is further improved.

[0024] It also includes a throat hoop 8, which is sleeved on the pipeline 3 to play a role of fixed support so that the pipeline will not leak.

[0025] The ends of pipe 4, pipe 5 and pipe 6 are all designed as flat tubes with elliptical structures. Pipe 4, pipe 5 and pipe 6 are all provided with flanges 9 at the ends, which are used to connect the exhaust ducts of each cylinder and are sealed by welding to prevent leakage and breakage. The flanges 9 at the ends of pipe 4, pipe 5 and pipe 6 are interconnected integrated structures with higher structural strength and stable connection.

[0026] It also includes an expansion joint, and the pipeline 4 4, the pipeline 5 5 and the pipeline 6 6 are all connected to the pipeline 3 3 through an expansion joint. The expansion joint uses a welding connection method to respectively connect the pipeline 4 4, the pipeline 5 5, the pipeline 6 and the pipeline 3 3. The use of segmented welding can reduce the problem of fracture caused by vibration.

[0027] Working principle: Pipe four 4, pipe five 5 and pipe six 6 are connected to the exhaust ducts of each cylinder through flange 9, and the exhaust airflow enters pipe three 3 from three pipes with the same path distance. Under the control of valve 7, the airflow is discharged from pipe one 1 alone or pipe one 1 and pipe two 2 are discharged together.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
