NOx storage catalyst systems for spray-guided gasoline direct injection engines

DaimlerChrysler has introduced the second generation of gasoline direct injection engines with spray-guided stratified combustion and piezo injector technology. Such engines have a high fuel-saving potential compared with homogenously operated petrol engines. The solution for reducing NOx emissions during lean engine operation is exhaust gas aftertreatment using NOx storage catalysts. The integration of a NOx storage catalyst in an exhaust gas aftertreatment system is described. The working principles of NOx storage catalysts are outlined. Progress with the development of NOx storage catalysts that exhibit a higher ageing stability and a wider NOx operating range is discussed.
