Description

Technical Field

[0001] This invention belongs to the field of engine exhaust, specifically relating to a connection structure between a turbocharger and an exhaust pipe. Background Technology

[0002] For an engine layout where the exhaust pipe is located within a V-angle and the turbocharger is located on top of the engine, the installation height of the turbocharger is a necessary requirement for achieving a compact engine design. The left and right exhaust pipes need to merge and enter the turbocharger to form a three-way flow direction. According to the traditional design of the three-way pipe and flange installation structure, it is impossible to reduce the installation height of the turbocharger. Furthermore, the exhaust pipe and turbocharger operate in a vibration and high-temperature environment. Therefore, a connection structure is needed that can meet the sealing requirements of vibration impact and high-temperature deformation, while also being compact and occupying little space. Summary of the Invention

[0003] This invention provides a connection structure between a turbocharger and an exhaust pipe to meet the sealing requirements of the turbocharger under vibration and high temperature environments, and to provide a reliable structure for the compact arrangement of the turbocharger.

[0004] In order to solve the above technical problems, the present invention provides a turbocharger and exhaust pipe connection structure, characterized in that it includes a turbocharger (1), a right exhaust pipe (4), and a left exhaust pipe (11). The right exhaust pipe (4) is connected to the left exhaust pipe (11) through the corrugated pipe II (9). After the right exhaust pipe (4) merges the exhaust, it is connected to the turbocharger (1). The turbocharger (1) and the right exhaust pipe (4) are connected by a corrugated pipe. The corrugated pipe I (2) is threaded to the inlet of the turbocharger (1) volute. The corrugated pipe I (2) is fastened to the outlet of the right exhaust pipe (4) by a V-type clamp I (3).

[0005] Furthermore, sealing gaskets I are installed at both ends of the bellows I and between the inlet of the turbocharger volute and the end face of the right exhaust pipe. The sealing gaskets I are made of high-temperature resistant C-shaped steel plates.

[0006] Furthermore, the two ends of the corrugated pipe II are fastened with V-shaped clamps II.

[0007] Furthermore, a stop structure is designed at the connection between the bellows I and the right exhaust pipe.

[0008] Furthermore, liner I and liner II are respectively installed between the corrugated pipe I and the corrugated pipe II.

[0009] Furthermore, both ends of the liner I and the liner II are spherical. The spherical surfaces at both ends of the liner I are tangent to the inner wall of the corrugated pipe I, and the spherical surfaces at both ends of the liner II are tangent to the inner walls of the left exhaust pipe and the right exhaust pipe, respectively.

[0010] Furthermore, the outlet diameter of the right exhaust pipe (4) entering the turbocharger (1) is larger than the diameter of the pipe connecting to the left exhaust pipe (11).

[0011] Furthermore, the bellows I has four evenly distributed slots at its threaded end, which facilitates screwing it into the booster using tooling.

[0012] Beneficial effects: This invention has the following advantages: (1) The present invention integrates a three-way structure on one side of the exhaust pipe where the left and right exhaust pipes meet, which shortens the length of the exhaust pipe and improves the response speed of the turbocharger.

[0013] (2) The turbocharger and exhaust pipe are connected by a bellows, which provides axial flexibility compensation for the installation of the turbocharger, ensuring good sealing of the turbocharger and exhaust pipe under vibration and high temperature conditions. At the same time, the installation height of the turbocharger is reduced, the structure is compact, the space occupied is small, the assembly process is simple, and the engine compactness design requirements are met.

[0016] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below.

[0017] like Figure 1 As shown, the present invention proposes a turbocharger and exhaust pipe connection structure, comprising: turbocharger (1), bellows I (2), V-clamp I (3), right exhaust pipe (4), sealing gasket I (5), liner I (6), sealing gasket II (7), V-clamp II (8), bellows II (9), liner II (10), and left exhaust pipe (11); the right exhaust pipe (4) is connected to the left exhaust pipe (11) through bellows II (9), and the right exhaust pipe (4) is connected to the turbocharger (1) after merging exhaust. The turbocharger (1) and the right exhaust pipe (4) are connected by bellows, the bellows I (2) is threaded to the inlet of the turbocharger (1) volute, and the bellows I (2) is fastened to the outlet of the right exhaust pipe (4) by V-clamp I (3); In this embodiment of the invention, the two ends of the bellows I (2) are sealed with the middle of the inlet of the turbocharger (1) volute and the end face of the right exhaust pipe (4) by a sealing gasket I (5), which is a high-temperature resistant C-shaped steel plate.

[0018] In this embodiment of the invention, the two ends of the corrugated pipe II (9) are fastened with V-shaped clamps II (8).

[0019] The corrugated pipe I (2) and the right exhaust pipe (4) in the embodiment of the present invention are designed with a stop structure.

[0020] In this embodiment of the invention, liner I (6) and liner II (10) are respectively installed between the corrugated pipe I (2) and the corrugated pipe II (9).

[0021] In this embodiment of the invention, the two ends of the liner I (6) and the liner II (10) are spherical. The two ends of the spherical surface of the liner I (6) are tangent to the inner wall of the corrugated pipe I (2), and the two ends of the spherical surface of the liner II (10) are tangent to the inner walls of the left exhaust pipe (11) and the right exhaust pipe (4), respectively.

[0022] In this embodiment of the invention, the outlet diameter of the right exhaust pipe (4) connected to the turbocharger (1) is 1.45 times the diameter of the connecting pipe to the left exhaust pipe (11).

[0023] The bellows I (2) of this embodiment is designed with four evenly distributed slots (12) at the threaded end, which makes it easy to screw into the booster using tooling.

[0024] The usage process of this embodiment is as follows: First, install the turbocharger, bellows I, and gasket I. Use a tool to clamp bellows I into its slot and tighten it with appropriate torque. Then, install the right exhaust pipe behind the cylinder head, followed by the left exhaust pipe. Simultaneously, install bellows II, liner II, and clamp II connecting the left and right exhaust pipes. Finally, install the turbocharger. Align bellows I and gasket II with the right exhaust pipe's stop and tighten using V-clamp I. When the engine is operating normally, the exhaust from the left exhaust pipe merges with the right exhaust pipe through bellows II, and then enters the turbocharger through bellows I.

[0025] The exhaust pipe on one side integrates a three-way structure that allows the left and right exhaust pipes to merge, shortening the length of the exhaust pipe and improving the turbocharger's response speed. The turbocharger and exhaust pipe are connected by a corrugated pipe, which provides axial flexibility compensation for the installation of the turbocharger and ensures good sealing of the turbocharger and exhaust pipe under vibration and high temperature conditions. At the same time, the installation height of the turbocharger is reduced, resulting in a compact structure, small space occupation, and simple assembly process, meeting the compact design requirements of the engine.

[0026] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
