Abstract
An exhaust gas dilution device according to an exemplary embodiment of the present invention includes a head part, ejector unit, a nozzle part, and a dilution part. The head part has a space part into which an exhaust gas flows and a through-hole formed through the center axis direction to be connected to the space part. The ejector unit is coupled to the head part and has a first discharge hole formed passing through the center axis direction to be connected to the through-hole and connected to a first inlet to which primary dilution air is supplied. The nozzle part is inserted into a first discharge hole through the through-hole and has a second discharge hole that penetrates in the center axis direction so that the exhaust gas flowed into the space part is sucked and ejected into the first discharge hole as the primary dilution air moves through the first discharge hole. The dilution part has a first flow path part into which a primary dilution gas, which is generated and discharged after the exhaust gas and the primary dilution air are mixed in the first discharge hole, flows, and a second flow path part connected to the first flow path part and guiding secondary dilution air to be mixed with the primary dilution gas, and generates a secondary dilution gas as the primary dilution gas and the secondary dilution air are mixed.
