1. Control of EGR and VGT for emission control and pumping work minimization in diesel engines
Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER
2. Model-Based Diesel Engine Management System Optimization - A Strategy for Transient Engine Operation
Sammanfattning : To meet increasingly strict emission legislation and stronger demands on fuel consumption, typical passenger car diesel engines become increasingly complex with more and more controllable systems added. These added systems open up for the possibility to operate the engine at more efficient conditions, but it also becomes more challenging to optimize the settings in the engine management system.

3. Evaluation of test cycles for freight locomotives
Sammanfattning : Diesel locomotives provide versatility to the railway system as they do not depend on electric feeding. Worldwide they constitute important parts of locomotive fleets used for various tasks such as mainline services, shunting and terminal operations. The main drawbacks are emissions of CO2, NOx and other pollutants. LÄS MER
4. Studies of a Heavy-Duty Diesel Aftertreatment System Based on the NOX Storage and Reduction Technology
Sammanfattning : 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. LÄS MER
5. Activation of epithelial signal transduction pathways, cytokine production and airway inflammation following diesel exhaust exposure
Sammanfattning : Adverse health effects of ambient air pollution are well recognised and include increased morbidity and mortality in respiratory and cardiovascular diseases. Diesel engines are major contributors to ambient particulate matter pollution and diesel particles have been shown to have strong toxicological and oxidative properties. LÄS MER
