Description

Technical Field

[0001] This utility model relates to the field of diesel outboard motor technology, specifically a Y-type multi-functional exhaust pipe for diesel outboard motors. Background Technology

[0002] Outboard motors, as the name suggests, are propulsion engines installed on the outside of the hull (ship's side). They are usually suspended on the outside of the stern plate and are also called outboard motors. Outboard motors are highly integrated and easy to install and purchase, making them the preferred power source for personal recreational boats. They are also widely used in fishing and commercial operations. Outboard motors need to exhaust exhaust through an exhaust pipe when in use.

[0003] Existing exhaust pipes are inconvenient to use for noise reduction, resulting in loud exhaust noise and pollution. Therefore, existing exhaust pipes cannot meet people's work needs and cause inconvenience. Hence, there is an urgent need for a Y-type multi-functional exhaust pipe for diesel outboard motors to solve the above-mentioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a Y-type multi-functional exhaust pipe for diesel outboard motors, which has noise reduction capabilities and solves the problems mentioned in the background technology.

[0008] Furthermore, the fixed box has a trapezoidal structure in its orthogonal view, and the first and second exhaust pipes are symmetrically distributed on the top of the fixed box, which facilitates the guidance of gas flow and ensures exhaust from both sides.

[0009] Furthermore, the first through hole is located at the end of the air inlet pipe that extends into the fixed box, and the air inlet pipe and the first partition and the second partition are respectively located at the end of the first air outlet pipe that extends into the fixed box. The end of the first air outlet pipe that extends into the fixed box is inclined, and the inclination angle is consistent with the angle of the outer wall of the fixed box, which is conducive to further noise dispersion.

[0010] Furthermore, the third through hole is located at the end of the second vent pipe that extends into the fixed box, and the end of the second vent pipe that extends into the fixed box is inclined, and the inclination angle is consistent with the angle of the outer wall of the fixed box, which is conducive to further noise dispersion.

[0011] Furthermore, the first exhaust pipe is connected to the second partition through it, and the front view of the first exhaust pipe is an "L" shaped structure, which facilitates effective exhaust of the first exhaust pipe.

[0012] Furthermore, the second exhaust pipe is connected to the second partition plate, and the front view of the second exhaust pipe is an "L" shaped structure, which facilitates effective exhaust of the second exhaust pipe.

[0013] Furthermore, the width of the first partition is smaller than the width of the second partition.
