A method pertaining to a liquid supply system which supplies liquid to a feed device () via which liquid is supplied to at least one consumption point (): Determining presence of air supplied upstream to the feed device (), and, when presence of air is found, of reducing operating power of the feed device () compared with ordinary operation. Also a computer program product containing program code (P) for a computer () for implementing the method. Also a device and a motor vehicle () which is equipped with the device.

Method pertaining to air removal from a liquid supply system and a liquid supply system

A method for cooling a dosing unit () pertaining to an SCR system for exhaust cleaning, wherein after cessation of exhaust flow, cooling a reducing agent dosing unit () by a reducing agent supplied to it. Also running a feed device to supply the coolant reducing agent at reduced power, compared with ordinary operation. A computer program product containing program code (P) for a computer () implements a method of the invention. Also an SCR system and a motor vehicle which is equipped with the SCR system are disclosed.

Method and device pertaining to cooling of dosing units of SCR systems

A method pertaining to an SCR system for exhaust cleaning, includes deciding about a need, after cessation of an exhaust flow, to cool a reducing agent dosing unit () by a reducing agent supplied to it, and includes predicting a temperature pattern of the dosing unit () as a basis for deciding about the need and predicting whether a predetermined temperature of the dosing unit will be reached after cessation of exhaust flow. Also a computer program product containing program code (P) for implementing the method, an SCR system and a motor vehicle which is equipped with the SCR system are disclosed.

A method pertaining to an SCR system in which reducing agent in liquid form is supplied to a feed device () and via which feed device reducing agent is supplied to at least one consumption point () from a container (): the steps of continuously detecting the feed pressure (P) which the feed device () furnishes, and controlling the operation of the feed device () on the basis of changes (P') in the feed pressure (P), with the object of reducing the impact of unwanted air supply at the feed device (). Also pertaining to a computer program product containing program code (P) for a computer () for implementing a method according to the invention. Also an SCR system and a motor vehicle which is equipped with the SCR system are disclosed.

Method pertaining to air removal from a dosing system at an SCR system and a SCR system

A method for an industrial robot to increase accuracy in movements of the robot. A first path is formed by bringing a tool supported by the robot to adopt a plurality of generated positions. A plurality of observed positions of the tool moving along the first path are determined. A second path is formed of the determined tool positions. A correction is determined by a path deviation between geometrically determined positions in the first path and the second path.
