1. Operating cycle representations for road vehicles
Sammanfattning : This thesis discusses different ways to represent road transport operations mathematically. The intention is to make more realistic predictions of longitudinal performance measures for road vehicles, such as the CO2 emissions. LÄS MER
2. The operating cycle representation of road transport missions
Sammanfattning : The difficulties that conventionally road vehicles are facing in meeting regulation standards require ad-hoc solutions. Moreover, the impellent shift of paradigm towards full electrification and partial automation is posing great challenges to the automotive industry, which has set a zero-emissions target to be reached within a short time horizon. LÄS MER
3. Mathematical modelling of operating cycles for road vehicles
Sammanfattning : Difficulties that commercial vehicles are facing in meeting regulation standards require ad-hoc solutions. Emissions can be dramatically lowered if the characteristics of the transport application are known in advance. LÄS MER
4. Waste Heat Recovery in Heavy Duty Diesel Engines
Sammanfattning : Over 50% of the energy released by burning fuel in a truck engine is lost as heat rather than being used to propel the vehicle. A promising method for capturing and reusing this heat, and thereby improving engine efficiency, is to exploit thermodynamic cycles for waste heat recovery (WHR). LÄS MER
5. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers
Sammanfattning : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. LÄS MER
