Description

Technical Field

[0001] The utility model relates to the technical field of turbocharger hole structures, in particular to a turbocharger muffler for an automobile engine. Background Art

[0002] A turbocharger combines a centrifugal compressor and turbine into a single unit. Its main difference from a gas turbine is that it lacks a combustion chamber and its associated systems. Instead, the turbine utilizes the exhaust energy of a reciprocating internal combustion engine, and the compressed air provided by the centrifugal compressor serves as the engine's charge. In a turbocharger, the compressor impeller and turbine are assembled on the same rotating shaft, called the rotor. Seals and thrust plates are also mounted on the same rotor shaft and rotate together.

[0003] Among them, turbocharging is prone to generate loud noise. In order to reduce the impact of noise, a corresponding muffler is usually required. There is a muffler for a turbocharger with patent announcement number CN220791368U. The internal connecting pipe and the expansion cavity are arranged by snap-fitting, so that the muffler itself adopts a snap-fitting form, and the muffler can be replaced without replacing the entire part. Therefore, the replacement cost itself is low, thereby reducing the operation and maintenance cost; the arc plate and the folding plate are arranged in combination, and the basic hanging groove and the external hanging groove are integrated into a snap-fitting form, and the setting of the sealing gasket can not only ensure the sealing effect, but also enable structural disassembly and assembly; the setting of the annular rubber plate and the sound-absorbing cotton can reduce the sound of the exhaust gas discharged by the turbocharged engine as much as possible, thereby playing a good silencing function.

[0004] However, the clamping structure of the device has the risk of aging and deformation, which may lead to connection defects and poor reliability in the long term. Utility Model Content
