Patent number: 9625346Abstract: A method for checking the leak-tightness of hydraulic components in an exhaust gas aftertreament unit of an internal combustion engine is disclosed. The exhaust gas aftertreament unit uses an electric motor to pump a liquid reductant from a reductant reservoir to a reductant injector that is kept closed.
