Description

Technical Field

[0001] The utility model belongs to the technical field of turbochargers, and in particular relates to an exhaust structure of a turbocharger. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipe to enter the cylinder with pressure. 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 increase in air pressure and density can burn more fuel. By increasing the amount of fuel and adjusting the engine speed accordingly, the engine output power can be increased.

[0003] During the use of the existing turbocharger, the exhaust gas generated will be discharged from the exhaust pipe and the exhaust pipe set on one side of the turbine. Since the exhaust gas discharged by the engine processed in the turbine chamber will contain a certain amount of oil, the oil will easily adhere to the filter of the exhaust pipe with the exhaust gas under long-term operation. The filter is usually disassembled and cleaned manually, which is time-consuming and labor-intensive, and the maintenance cycle is long. Therefore, we need to upgrade and transform it based on the existing technology. Utility Model Content
