Description

Technical Field

[0001] The utility model relates to the field of engine mufflers, and in particular to a built-in muffler for an engine. Background Art

[0002] In current technology, a muffler refers to a noise reduction device that can be used to reduce or reflect noise in an airflow duct with noise transmission, such as a pipe with a sound-absorbing lining and an elbow, or a pipe with a sudden change in cross-sectional area or other discontinuous acoustic impedance. Mufflers are also widely used in engines because of their functions. The most common mufflers on the market are directly connected to the engine body, beyond the engine body. Because they are outside the engine body and directly exposed to the outside world, they are difficult to protect during transportation. Utility Model Content

[0004] An engine built-in muffler comprises a muffler mounting seat, a muffler front baffle, a muffler exhaust pipe and flange, a muffler intake pipe and flange, and a muffler shell. The muffler exhaust pipe and flange and the muffler intake pipe and flange are connected to the muffler front baffle, the muffler front baffle is connected to the muffler shell, and the muffler mounting seat is fixed on the muffler shell.

[0005] Furthermore, an engine built-in muffler is provided, wherein the upper ends of the muffler exhaust pipe and the flange are fixed to the left side of the muffler front baffle, and the upper ends of the muffler intake pipe and the flange are fixed to the right side of the muffler front baffle.

[0006] Furthermore, an engine built-in muffler is provided, wherein the muffler shell wraps around the upper end cross-section of the muffler front baffle.

[0007] Furthermore, an engine built-in muffler is provided, wherein the muffler mounting base is fixed at the middle position on the left side of the muffler housing.

[0008] Furthermore, a muffler is built into the engine, and the muffler mounting base is fixedly connected to the engine frame.

[0009] Furthermore, an engine built-in muffler is provided, wherein the muffler is built into the engine via a muffler mounting seat.

[0010] Furthermore, an engine has a built-in muffler, wherein the exhaust pipe of the engine and the intake pipe of the muffler are connected via the flange of the muffler intake pipe and the flange.

[0011] Advantages of the present utility model: An engine-integrated muffler is installed inside the engine through a muffler mounting seat. The exhaust pipe of the engine and the intake pipe of the muffler are flange-connected through the muffler intake pipe and the flange. With a new structural design, the muffler is installed inside the engine frame, which not only ensures functionality but also protects the muffler during relocation and guarantees the integrity of the engine unit. Description of the Drawings
