摘要：

Stricter emission legislation for diesel vehicles will make exhaust after-treatment mandatory in the near future. Urea-SCR has been chosen for NOx reduction on trucks and busses. Since its effectiveness in reducing NOx is great, and since there is a trade-off between NOx emissions and fuel consumption, engines can be adjusted on fuel efficiency. This review article deals with subjects such as the description of SCR catalysts, catalytic systems, system performance, choice of reducing agent and durability.
