Patent ID: 8763372

Claim:
A control device, comprising: an electromagnetically controllable metering valve disposed in an exhaust gas system of an internal combustion engine; the metering valve configured to meter a reducing agent in the exhaust gas system via an electromechanical drive unit; the control device in signal communication with the electromechanical drive unit; the control device configured to actuate the electromechanical drive unit with a first current profile which includes a first holding current level when the metering valve is open; the control device configured to actuate the drive unit with a second current profile when the internal combustion engine is switched off, where the second current profile has a second holding current level that is increased with respect to the first holding current level; and a metering module comprising the metering valve and the drive unit; and the control device configured to heat up the metering module by initiating the second current profile.
