Abstract

The invention discloses a working-station-variable turbocharger. The working stations of the turbocharger can be changed manually according to the working conditions of an engine, so that the turbocharger is better matched with the working conditions of the engine, the variable working stations of the working-station-variable turbocharger are driven by a servo motor, the intervention degree of a worm wheel is linear, and the aborting feeling generated by the sudden intervention of the worm wheel does not exist. When the engine rotates at a low speed, the worm wheel can be positioned in the fully idle working station, resistance during the exhaust of the engine is greatly reduced, the performance of the engine is further improved, and the service life of the turbocharger is also prolonged. When the service life of the turbocharger reaches the limit, the working stations of the turbocharger can be changed to be the idle working stations, so that a gas distribution system of the engine is not affected and can be compared with that of a naturally-aspirated engine; therefore, the usage and maintenance cost of the turbocharger is reduced, and the economy is better.

Description

technical field [0001] The invention belongs to the field of new automobile technologies, and more specifically relates to a novel variable-position turbocharger which makes the performance of the engine more superior. Background technique [0002] Air turbocharging system is the most common turbocharging device in our daily life. The supercharger has no mechanical connection with the engine. It is actually an air compressor, which increases the intake air volume by compressing air. The inertial momentum of the exhaust gas discharged from the engine is used to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller. The impeller 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, and th...
