1. A flow distribution plate associated with an engine exhaust gas aftertreatment device, wherein the plate is perforated and is adapted to be arranged at an inlet to an exhaust gas purifying unit to improve the flow distribution of exhaust gas into the purifying unit, wherein the flow distribution plate is curved in relation to the inlet, such that a more uniform flow velocity distribution is achieved over the inlet, wherein the curvature of the flow distribution plate is asymmetric and formed depending on the direction of the inflow of exhaust gas in relation to the inlet, wherein the flow distribution plate is curved such that the incoming exhaust gas with the highest flow velocity hits a part of the flow distribution plate, which is furthest away from the inlet to the purifying unit.
