The exhaust body discharged from the engine is provided with a mixing body 12, 112, 132 that can be disposed in an exhaust gas conduit having a gas collision surface 12; 112; 132 and an injection collision surface 14; 114; 161. Reducing agent, which can be supplied onto the impingement surfaces 15, 115, 160 and transversely to the exhaust gas flow, flows into the exhaust gas conduit 1 so that it can impinge on the impingement impingement surfaces 14, 114, 161. A mixing device for mixing an exhaust gas of a engine and a reducing agent, and an exhaust gas purification system having such a mixing device, wherein the injection impingement surfaces 14, 114, 161 and the gas impingement surfaces 15, 115, 160 are mixed main bodies. Form a separate partial region of (12, 112, 132). The mixing device is used for constant distribution of the reducing agent through the cross section of the exhaust gas conduit and for constant mixing with the exhaust gas.n n n n Exhaust gas purification system, injection collision surface, gas collision surface, mixing device, reducing agent |
