The mixing and evaporation device (12) has a support body, which is transversely extending to an axial direction (20) of the device, and is enclosing through-flow cross-section of the device in a circumferential direction. A guide vane is arranged in the support body, and protrudes transversely to the axial direction. The guide vane has a roof-shaped profile, where two guide surfaces are interconnected on a ridge or an apex. An independent claim is included for an internal combustion engine for use with a selective catalytic reduction catalytic converter.
