An exhaust additive distribution arrangement for an exhaust system of an internal combustion engine () includes an exhaust duct element (), an exhaust additive injection unit (), and a primary vaporization element (); wherein the primary vaporization element () is a tubular body arranged in the interior of the exhaust duct element (), has a predefined space between an inner surface of the exhaust duct element () and an outer surface of the primary vaporization element (), and protrudes from the exhaust duct element () at an outlet end; and wherein the exhaust additive injection unit () is arranged to inject exhaust additive liquid from a point at the inner surface of the exhaust duct element () towards an inner surface of the primary vaporization element (). The exhaust additive injection unit () is of the liquid-only type, and the primary vaporization element () has a length that is sufficiently short to allow injected exhaust additive liquid to run off of the outlet end of the primary vaporization element (). The present invention also concerns an exhaust additive distribution system and a vehicle () comprising the exhaust additive distribution arrangement.
