Abstract: A frame for a plastic tank for a motor vehicle, containing at least one means for attaching an internal reinforcing element of the plastic tank which is intended to connect two opposite walls of said plastic tank. The at least one means for attaching the internal reinforcing element includes at least one first structure configured to snap-fit at least a portion of the internal reinforcing element. The at least one first structure contains at least two bodies that are movable relative to each other. The at least two bodies are provided with a holding means configured to hold the internal reinforcing element in a direction opposite to a snap-fitting direction, and at least one stop element, separate from the at least two bodies, protruding in a direction opposite to the snap-fitting direction in order to provide a stop for the internal reinforcing element when said element is snap-fit into place.

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 σ 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 σ 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: A vehicle system includes a tank for storing an aqueous solution; and a UV light decontamination module configured for decontaminating aqueous solution stored in the tank. The UV light decontamination module is arranged in a wall of the tank. The UV light decontamination module includes a light source compartment which is accessible from an external area outside of the tank; and a light transmission member configured to transmit UV light from the light source compartment to a liquid space in fluid communication with aqueous solution stored in the tank. The light source compartment includes a light source to emit UV light through the light transmission member to the liquid space.
