Abstract

The invention belongs to the technical field of turbochargers, and relates to a turbocharger with an electronic fast start split structure. The turbocharger comprises a turbine spindle and a motor mounted on the turbine spindle. A first middle shell is mounted on the axial diameter of the side, extending out of the motor, of the turbine spindle. A first bearing is arranged between the first middleshell and the turbine spindle. A second middle shell is mounted on the axial diameter of the other side, extending out of the motor, of the turbine spindle. A second bearing is arranged between the second middle shell and the turbine spindle. The part between a left end cover of the motor and the first middle shell as well as the part between a right end cover of the motor and the second middle shell are sealed through multi-step structures correspondingly. The outer end face of the first middle shell is in sealed connection with a pressure expander. The outer end face of the pressure expander is in sealed connection with a compressor shell. A compressor impeller is mounted on the axial diameter, penetrating through the first middle shell and the pressure expander to extend into the compressor shell, of one end of the turbine spindle. According to the turbocharger, the natural air-sucking form of the turbocharger is effectively avoided, and pressure-increasing pressure air entering anengine and engine starting are synchronous.

Description

technical field [0001] The invention belongs to the technical field of turbochargers, and relates to a turbocharger with an electronic quick start split 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 chamber, 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. 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. The existing turbocharged engine adopts the form of natural suction at the initial stage of starti...
