Beschreibung
Zusammenfassung:	The invention relates to a method (100) for releasing a clamping of an electromagnetically operated metering valve in a metering system for metering a urea-water solution for an SCR catalytic converter into the exhaust duct of an internal combustion engine. The method is characterized in that the metering valve is loaded with the urea-water solution at a predetermined pressure (104). 本发明涉及一种用于松开以电磁方式来操纵的计量阀的夹紧状态的方法（100），所述计量阀处于用于将用于SCR催化器的尿素水溶液配入到内燃机的废气通道中的计量系统中。该方法的特征在于，在预先给定的压力下给所述计量阀加载（104）尿素水溶液。
