    Abstract: A method for cooling a dosing unit (250) pertaining to HC dosing system for exhaust cleaning. The dosing unit (250) for fuel and a feed device (230) to supply fuel for cooling. The steps include cooling a fuel dosing unit (250) by fuel supplied to intermittently, in mutually successive respective periods of zero operating power of the feed device, or running at certain operating powers by running a fuel feed device (230) at reduced power compared with ordinary operation. A computer programme product containing programme code (P) for a computer (200; 210; 500) for implementing the method. An HC dosing system. A motor vehicle equipped with the system.
