1. Multiscale methods for the fundamental understanding of diesel soot mitigation
Abstract : Current regulations for diesel exhaust emissions cannot be met by engine improvements alone, and for this reason the diesel particulate filter (DPF) is a widely used aftertreatment component for the control of diesel particulate matter (PM). The DPF functions by trapping PM and destroying it by oxidation. READ MORE

2. Studies of a Heavy-Duty Diesel Aftertreatment System Based on the NOX Storage and Reduction Technology
Abstract : The legislative limits for NOX emissions in the exhaust gas from heavy-duty diesel engines will be decreased in the European Union from today 3.5 g/kWh (Euro IV) to 2.0 g/kWh in 2008 (Euro V). In the USA and Japan a similar trend can be seen. READ MORE

3. Deactivation of diesel oxidation catalysts
Abstract : To meet the demand for heavy- and light-duty diesel vehicles on expansive markets while complying with current and future emission standards, it is necessary to reinsure the long-livety of the applied exhaust aftertreatment technology. Loss of catalytic performance may be associated with environmental as well as economical consequences. READ MORE

4. Effects of trace elements in biodiesel on the performance of diesel oxidation catalysts in heavy-duty vehicles
Abstract : To reduce net greenhouse gas emissions, a shift towards adoption of biofuels is ongoing in the transport sector. Heavy-duty diesel vehicles are equipped with aftertreatment equipment, comprising of catalysts and filters, and how this equipment is affected by the use of biofuels is not yet fully understood.

5. Fundamental studies of catalytic systems for diesel emission control
Abstract : Due to global lean exhaust gas and new emission regulations, exhaust aftertreatment systems of diesel engines are more and more sophisticated and composed of a series of catalytic units. In the present work, two of these catalytic systems were studied with different approach. READ MORE
