1. An apparatus for diluting exhaust gas, the apparatus comprising:
a stagnant air forming unit configured to form stagnant air by decelerating a flow velocity of introduced exhaust gas;
an ejector unit connected to a front end of the stagnant air forming unit, provided with
an exhaust gas suction passage, which is a passage through which the stagnant air is introduced from the stagnant air forming unit and the exhaust gas flows, and
a dilution air supply passage, which is a passage through which introduced primary dilution air is branched and supplied to a plurality of points of the exhaust gas suction passage, and introducing the exhaust gas through the exhaust gas suction passage and discharging the exhaust gas toward a front by a difference in pressure according to a supply of the primary dilution air; and
a dilution unit coupled to a front end of the ejector unit and supplying secondary dilution air to primary dilution gas discharged by mixing the exhaust gas and primary dilution air to generate secondary dilution gas.
