Embodiment Construction

[0030] exist figure 1 A valve regulator system 1 with a valve regulator 2 as actuating applicator is provided. Such a valve regulator 2 can be arranged, for example, as a throttle regulator in the air supply section of the motor vehicle, or as a wastegate regulator in the bypass line of the turbine of the exhaust gas turbocharger in the exhaust gas outlet section. .

[0031] Furthermore, such a valve adjuster 2 can be used, for example, in a wastegate in a bypass line of a turbine of a turbocharger or in a bypass line of a bypass valve in a two-stage turbocharger. However, the use of such a valve regulator system is not restricted to this application, but such a valve regulator system can be used in the air supply section or exhaust gas discharge section of an internal combustion engine or other systems for controlling the mass flow of a medium. each valve regulator.

[0032] The valve regulator 2 serves to control the mass flow of the medium through the line 3 . For this ...

Abstract

The invention relates to a method for controlling a quality flow, especially a quality flow in an engine system having an internal combustion engine by means of a regulation exerting device for regulating elements, especially by an air valve regulator. The method comprises the steps of providing (S1) regulating parameters which describe the quality flow to be regulated by a regulating element (4); triggering the regulation exerting device (2) on the positions of the regulating parameters according to the attachments of the regulating element (4) when the regulating parameters are larger than a predetermined regulating parameter threshold value; and triggering (S4) the regulation exerting device (2) to make the regulating element (4) in a close state when the regulating parameters are smaller than the predetermined regulating parameter threshold value, wherein, the closing force of the regulating element (4) is adjusted according to the regulating parameters.

Description

technical field [0001] The invention relates to a valve regulator for controlling a mass flow, in particular for controlling a gas mass flow in an air intake or exhaust gas discharge section of an engine system of a motor vehicle. Furthermore, the invention relates to a method for operating a controller of a valve regulator. Background technique [0002] Modern internal combustion engines have an air inlet section in which a gas mass flow is delivered, and an exhaust gas outlet section. The air supply section is used to supply ambient air to the cylinders of the internal combustion engine, and the exhaust gas discharge section is used to discharge the combustion exhaust gases injected from the cylinders. [0003] In order to control the gas mass flow, so-called valve regulators are provided, for example throttle valve regulators for throttle valves, wastegate regulators for wastegate valves in the bypass line of turbochargers, wastegate regulators with Valve regulators for...
