Beschreibung
Zusammenfassung:	The invention relate to a method for cleaning a valve. The method and the system for cleaning a brake booster aspirator shut-off valve are provided. The shut-off valve is operable to selectively permit flow of intake air through an aspirator; the aspirator bypasses a throttle of an engine and provides a vacuum source for a brake booster. The method comprises determining whether the shut-off valve may require cleaning, opening the shut-off valve so as to permit a flow of air through the shut-off valve and clean the shut-off valve and adjusting the throttle position of the engine to compensate for the additional flow of intake air through the aspirator. 本发明涉及用于清洁阀门的方法。提供种用于清洁制动助力器吸气器切断阀的方法和系统。切断阀能够操作以选择性地允许进气空气流穿过吸气器；吸气器绕过发动机的节气门并且为制动助力器提供真空源。该方法包括确定切断阀是否会需要清洁，打开切断阀以便允许空气流穿过切断阀并且清洁所述切断阀，以及调节发动机的节气门位置以补偿穿过吸气器的附加进气空气流。
