Turbocharger with remarkable noise reduction performance

Abstract

The invention discloses a turbocharger with a remarkable noise reduction performance. The turbocharger comprises a turbine motor housing and a gas compressor housing, wherein a noise reduction layer is arranged on the inner wall of the turbine motor housing; an impeller of a gas compressor is connected with an impeller of a turbine motor through a turbocharger shaft; a vibration-damping gasket ismounted at one side of the impeller of the gas compressor; and micro holes are formed in the inner wall of the gas compressor housing. According to the turbocharger disclosed by the invention, the noise reduction layer is arranged on the inner wall of the turbine motor housing, so that noises generated in a working process of the impeller of the turbine motor are absorbed by the noise reduction layer, and the noise reduction effect is achieved on the turbocharger; the vibration-damping gasket is positioned on the end part of the turbocharger shaft, so that vibrations generated in the working process of the turbocharger shaft can be reduced, and buffer performance is improved, and therefore, noises generated by high-amplitude vibrations in the working process of the turbocharger shaft are reduced; and the micro holes are formed in the inner wall of the gas compressor housing, so that the noises generated in the rotation process of the impeller of the gas compressor are diffused throughthe micro holes, and therefore, the noise reduction effect is achieved.

Description

technical field [0001] The invention relates to a turbocharger, in particular to a turbocharger with significant noise reduction performance. Background technique [0002] The turbocharger is actually a kind of air compressor, which increases the air intake by compressing the air. It uses the inertial momentum of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which is fed by the impeller. The air from the air filter pipe is pressurized into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The pressure and density of the air increase to burn more fuel. Increase the amount of fuel and adjust the engine speed accordingly. The output power of the engine can be increased, and the general turbocharger will produce high-intensity noise due to the rotation of the...

When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The pressure and density of the air increase to burn more fuel. Increase the amount of fuel and adjust the engine speed accordingly. The output power of the engine can be increased, and the general turbocharger will produce high-intensity noise due to the rotation of the turbine impeller and the compressor impeller during work, and when the air and exhaust gas circulate in the turbocharger, it will also make a lot of noise
