Title:
VARIABLE GEOMETRY TURBOCHARGER CONTROL METHOD, APPARATUS, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/169760
Kind Code:
A1
Abstract:
A variable geometry turbocharger control method, applied in a vehicle. The vehicle comprises an engine having a variable geometry turbocharger, the variable geometry turbocharger comprises a nozzle ring, and the method comprises: obtaining target state information for the engine, the target state information being related to an engine state (S100); once the target state information complies with a preset condition, controlling the nozzle ring to execute a self-cleaning operation; the self-cleaning operation comprises controlling the nozzle ring, according to a preset rate, to switch back and forth between a completely open state and a completely closed state a preset number of times (S200). Further disclosed is a variable geometry turbocharger control apparatus and a vehicle having said apparatus. In the control method, by utilizing extreme change in the degree of opening of the nozzle ring to produce vibrations, carbon deposits sticking to the nozzle ring can be removed, achieving nozzle ring self-cleaning and preventing nozzle ring jamming malfunctions.
