A device for use in a truck for lowering the temperature of exhaust gas of a combustion engine has a diffuser 1, which is provided with a cylindrical housing 3 provided with an inlet opening 5 in an end wall 7 and an elongated axially extending outlet opening 9 in the cylinder wall. The device furthermore has a bent guide plate 25 which extends from the outlet opening 9, so that, as a result of the Coanda effect, the hot exhaust gas is diverted along the plate and the jet widens, so that a better mixing with the ambient air, and hence greater cooling, takes place. |
