Abstract

Advanced exhaust gas aftertreatment solutions are one of the key components for the development of modern powertrain systems. Currently new challenges are foreseen to widely influence the design of next generation aftertreatment systems. These challenges are based on the one hand on the implementation of new drive cycles (e.g. World Harmonized Test Cycle) as well as on new test procedures e.g. on-road real driving emission tests in the EU. On the other hand, the increasing electrification of the powertrain in order to reduce CO2 emissions influences engine-out emissions and the thermodynamic situation in the exhaust system. The main focus of this study is to develop dedicated exhaust gas aftertreatment solutions for clean and efficient diesel-hybrid-vehicles at reasonable system cost.
