Beschreibung
Zusammenfassung:	A wastegate system of a vehicle includes: a wastegate valve configured to regulate exhaust flow through a turbine of a turbocharger of an engine; a wastegate actuator including a lever that is mechanically coupled to the wastegate valve via one or more linkages and that is configured to move linearly based on a pressure within an interior of the wastegate actuator; a resonator that is fluidly coupled to the interior of the wastegate actuator via a first one or more hoses and that is configured to counteract force attributable to pressure changes in the exhaust from combustion events within the engine; and a regulator valve that is fluidly connected between a pneumatic source and the resonator via a second one or more hoses and that is configured to regulate the pressure within the interior of the wastegate actuator.
