Abstract

The invention belongs to the technical field of engine turbocharging, and relates to a vortex end outlet structure with a core. The vortex end outlet structure with the core comprises a turbine shell, wherein a turbine capable of rotating around the axis of the turbine shell is arranged in an inner cavity of the turbine shell; a turbine shell outlet is formed in a shell body of the turbine shell; the core is arranged on the center position of the outlet of the turbine shell; a turbine shaft is integrated on the turbine; a gap is formed between the core and the turbine shaft; and the core is integrated on a transition joint or the turbine shell. The vortex end outlet structure with the core is simple and reasonable in structure, and is low in producing and manufacturing cost; and one core is additionally arranged on the center position of the vortex end outlet so that integral efficiency of the vortex end can be improved.

Description

technical field [0001] The invention belongs to the technical field of engine turbocharging, and relates to a cored vortex end outlet structure. Background technique [0002] A turbocharger is actually an air compressor that compresses air to increase intake air. It uses the inertial momentum of the exhaust gas discharged from the engine to drive the turbine in the turbine housing, and the turbine drives the coaxial impeller, which presses the air sent by the air filter pipe to pressurize it 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, and the pressure and density of the air increase to burn more fuel. Increase the fuel volume and adjust the engine speed accordingly. , the output power of the engine can be increased. [0003] A turbocharger is generally composed of three parts: a vortex end, a pressure end and an intermediate bod...
