A GAS FLOW UNIT, A GAS TREATMENT DEVICE AND A COMBUSTION ENGINE PROVIDED THEREWITH

摘要

A gas flow unit comprising a gas flow inlet (2), a gas flow outlet and (3) a gas flow chamber (4) configured to convey a gas flow from the inlet (2) to the outlet (3), wherein the gas flow inlet (2) is configured to convey the gas flow in a first direction (11) into the gas flow chamber (4) and wherein the gas flow outlet (3) is configured to convey the gas flow in a second direction (12) from the gas flow chamber (4), wherein the second direction (12) is angular in relation to the first direction (11), and wherein the gas flow inlet (2) is an inlet into the gas flow chamber (4) and the gas flow outlet (3) is an outlet from the gas flow chamber (4). In the first gas flow direction (1 1), the gas flow chamber (4) extends beyond a projection of an outer periphery of the gas flow outlet (3) and defines a prolongation (13) configured for conveying a first part (14) of the gas flow such that it enters the gas flow outlet (3) from a different direction than a second part (15) of the gas flow entering the gas flow outlet (3) without passing through said prolongation (13).
