Summary

In order to comply with the European 2005 legislation for diesel cars improved catalyst efficiencies for all emission components are needed. Apart from optimizing engines and engine management systems, the oxidation catalyst for converting HC and CO has to be designed for the specific demands of direct injected turbo-charged diesel engines. Because of the trade off between NOx and particulate (PM) engine out emissions, cars with higher mass in particular might require increased PM efficiency. Tests were conducted using a Volvo S60 in order to investigate the emission potential of various new diesel catalyst systems, such as PM Catalysts, Hybrid Catalysts and Pre-Turbo-charger Catalysts.
