21. 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.

22. Optimal Speed and Powertrain Control of a Heavy-Duty Vehicle in Urban Driving
Sammanfattning : A major challenge in the transportation industry is how to reduce the emissions of greenhouse gases. One way of achieving this in vehicles is to drive more fuel-efficiently. LÄS MER
23. Conceptual Design of Semi-Closed Oxy-Fuel Combustion Combind-Cycle
Sammanfattning : Accelerating actions to mitigate CO2 emissions was one of the important messages at the UN Climate Summit 2014. About 85 % of the world’s energy is provided through the burning of fossil fuels, which is the main source of CO2 emissions. LÄS MER
24. Urban driving patterns - characterisation, variability and environmental implications
Sammanfattning : Driving patterns, i.e. the speed and acceleration profiles of vehicles affect exhaust emission and fuel consumption considerably. LÄS MER
25. Energy Efficiency in Winter Road Maintenance - A Road Climatological Perspective
Sammanfattning : Practices in winter road maintenance are dependent on the climate and weather impacting roads and the road users’ requirements. As in many other fields of transportation, it is of interest to investigate fuel efficiency potentials in the different aspects of the road maintenance area. LÄS MER
