Abstract

The invention discloses a variable flow turbine pressurizer, comprising a turbine shell (15), a turbine (14) and a pressing shell (21). In the turbine shell (15), a channel A (18) and channel B (19) which are parallel to each other are arranged from an inlet (17) of the turbine shell to the turbine (14); and a rotary valve (5) for totally closing the channel A (18) is arranged in the channel A (18). By using the technical scheme, the energy in the exhausted gas of an engine is fully used, thereby the supercharging of the pressurizer in the low working condition of the engine is effectively improved, the pressurizer can efficiently work from small flow to large flow, and the ideal matching of the turbine pressurizer and the engine can be realized at a full working condition.

Description

technical field [0001] The invention belongs to the technical field of automobile construction, and relates to the structure of an automobile engine. More specifically, the invention relates to a variable flow turbocharger. Background technique [0002] Supercharging technology has been widely used in the field of engines, especially in the field of diesel engines. The supercharging technology can greatly increase the output power and torque of the engine without increasing the displacement. Since the size and weight of the engine itself do not increase significantly, and the use of other technologies, such as exhaust gas intercooling, can significantly improve efficiency, thereby achieving the purpose of significantly reducing fuel consumption and emissions while increasing engine power and torque. Superchargers are now standard equipment on diesel engines. In the gasoline engine market, supercharged models are also rapidly gaining popularity. When the engine is in high ...
