Abstract

The invention discloses a vehicle and a supercharging system. The supercharging system comprises a turbine, a valve assembly and an actuator. At least two turbine flow channels used for being in sealed connection with an engine exhaust port are arranged inside a volute of the turbine and are mutually independent of each other. The valve assembly is connected with the turbine and used for controlling connection and disconnection of the turbine flow channels, so that the flow cross section of the turbine is changed. The actuator is connected with the valve assembly and used for controlling the valve assembly to act, so that the flow cross section under low engine working conditions is smaller than that under high engine working conditions. The supercharging system provided by the invention can be used for changing the flow cross section of the turbine through the valve assembly, the flow capacity of the turbine under the high engine working conditions is high, the supercharging pressure of the turbine under the low engine working conditions is large, and an engine performance optimization effect is achieved.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine supercharging, and more specifically, relates to a supercharging system. Furthermore, the invention also relates to a vehicle comprising the above-mentioned charging system. Background technique [0002] Turbocharging technology is currently one of the necessary technologies to improve fuel economy, emission characteristics and power performance of internal combustion engines. Since the internal combustion engine is a reciprocating power machine, its operating range is wide, while the turbocharger is a rotary machine, and its efficient operating range is narrow. Therefore, when the traditional turbocharger is matched with the internal combustion engine, it can only ensure that the internal combustion engine has a good effect within a certain range of working conditions. There is a problem with deteriorating engine performance. [0003] To sum up, how to improve the matching b...
