Embodiment Construction

[0056] In this detailed description, various embodiments of the cleaning system according to the invention are described primarily with reference to sensors in an aftertreatment system or an exhaust gas recirculation device. However, the invention is equally well applicable to other vehicle components, such as components of the vehicle's heat exchanger and mixture preparation system.

[0057] Vehicles contemplated according to the present invention include any type of vehicle, such as cars, buses, trucks, boats, ships, trains, covering any ground, sea or air vehicle and the like. Thus, the invention may generally be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art. . Like reference numerals refer to like elements throughout.

Abstract

The present invention relates to a cleaning system (300) for removal of contaminants from a surface (308) of a vehicle component (202; 306; 405; 406; 420; 407; 418) exposed to a gas or fluid flow, thecleaning system comprises: an excitation device (206; 302; 600; 700) adapted to be attached to the vehicle component in the vicinity of the surface exposed to contaminants, wherein the excitation device is configured to cause the surface to mechanically vibrate by transferring a vibrational excitation to the surface; wherein the frequency of the vibrational excitation is controllable, based on the configuration of the vehicle component as well as other modeled / measured parameters.

Description

technical field [0001] The present invention relates to a cleaning system for removing contaminants from the surface of vehicle components. The invention also relates to a method for cleaning the surface of a vehicle component. Background technique [0002] A vehicle's emission control system most commonly includes a catalyst unit (eg, selective catalytic reduction device, SCR device) for reducing the level of nitrogen oxides released into the ambient air. Furthermore, so-called exhaust gas recirculation devices are often used to recirculate the exhaust gas flow back into the intake air flow of the engine cylinders, for example to reduce the oxygen content (thus reducing NOx emissions) of the combustion process of the engine and to cool the combustion gases . [0003] In order to monitor the emission levels in the exhaust and the performance of the powertrain control systems, various types of sensors are placed in the exhaust stream. For example, an oxygen sensor commonly...
