EXHAUST PIPE ARRANGEMENT FOR DISCHARGING EXHAUST FROM A COMBUSTION ENGINE

摘要

The invention relates to an exhaust pipe arrangement (50) for discharging exhaust from a combustion engine (202) through an exhaust pipe (10), particularly for a combustion engine (202) with an exhaust gas aftertreatment system (204) requiring high temperatures in one or more operational modes, comprising an end section (16) terminated by an exhaust gas outlet (18). A diffuser section (20) is provided in the exhaust pipe (10), the diffuser section (20) having a first end (102) in a distance from the outlet (18) and a second end (104) closer to the outlet (18) is arranged in vicinity of the outlet (18), wherein at least one vane (110) with an airfoil profile (112) extends in an axial direction (130) from the first end (102) to the second end (104) of the diffuser section (20).
