Description

Technical Field

[0001] The utility model relates to the field of turbochargers, in particular to a turbocharger with noise reduction effect. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial impact of exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine in turn drives the coaxial impeller, which pressurizes the air sent by the air filter pipe and pressurizes it into the cylinder. The main noise of the turbocharger is caused by the rotation of the impeller. When the noise inside the turbocharger is too loud, it is not only not conducive to environmental protection, but also causes great interference to personnel. Therefore, it is necessary to reduce the noise of the turbocharger. Publication No. CN 220452328 U discloses a turbocharger with noise reduction effect, which includes: a turbine housing, a turbine gas outlet is provided on the surface of the turbine housing; a compressor housing, a compressor air inlet is provided on the surface of the compressor housing, and the turbine gas outlet and the compressor air inlet are both detachably connected to a silencer by screws.

[0003] In the above technical solution, when silencing the turbocharger, multiple bolts are used to fix the silencer to the surface of the device. When the user needs to remove the silencer, all the bolts need to be removed one by one, which is quite troublesome. Therefore, we propose a turbocharger with noise reduction effect to solve this problem. Utility Model Content
