FIELD: physics.
SUBSTANCE: system comprises a feeding device for feeding a reducing agent into a dosing device from a reducing agent container. The dosing device comprises a valve device, an expansion section and heating devices. The method comprises the step of heating the said dosing device, prior to cutting off the supply of the reducing agent into the said dosing device, up to such a degree that when the reducing agent freezes in the said dosing device, the freezing process is controlled such that expansion due to the freezing of the reducing agent in the said dosing device occurs substantially in the said expansion section.
EFFECT: group of inventions lowers the risk of the unfavourable action of low ambient temperature on the dosing device.
