    Abstract: A method of controlling water injection in an internal combustion engine for a motor vehicle in case of freezing cold weather. The method includes: controlling the quality of the water, having a first sub-step of disapproving the quality of the water if the electrical conductivity ? of the water is not zero nor close to zero when the temperature T of the water is 0° C. or less and a second sub-step of approving the quality of the water if the electrical conductivity ? of the water is zero or close to zero when the temperature T of the water is higher than ?4° C., preferably higher than ?2° C. The method further includes a second sub-step of preventing water injection if the quality of the water is disapproved and a third step of allowing water injection if the quality of the water is approved.

    Abstract: The invention relates to a pump (2) intended to pump an additive in an SCR system for a vehicle. The pump is configured to rotate in a first direction of rotation in order to convey additive stored in a tank towards an injector via an injection channel. The pump includes a chamber (23) which houses a gear system (22). The chamber (23) is in fluid communication with the tank and the injection channel via an inlet channel (24) and an outlet channel (25) respectively. The pump is such that the inlet channel and the outlet channel are arranged so that after draining the injection channel, the chamber collects and retains the additive.
