TURBOCHARGING DEVICE AND METHOD THEREFOR, AND SUPERCHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/233431
Kind Code:
A1
Abstract:
Disclosed is a turbocharging device (10), comprising a starter generator (1), a compression wheel (2), a first-stage turbine wheel (3) and at least one second-stage turbine wheel (4), which are sequentially arranged. Engine exhaust gas flows from the first-stage turbine wheel (3) to the second-stage turbine wheel (4), and the engine exhaust gas pushes the first-stage turbine wheel (3) and the second-stage turbine wheel (4) to rotate. The turbocharging device (10) uses the starter generator (1), such that the problem of a hysteresis effect of turbine wheels in the prior art is solved, and the utilization rate of engine exhaust gas is improved by means of the arrangement of the first-stage turbine wheel (3) and the second-stage turbine wheel (4). Further disclosed are a method for using the turbocharging device (10), and a turbocharging system comprising the turbocharging device (10).
