16. Automotive Climate Systems - Investigation of Current Energy Use and Future Energy Saving Measures
Sammanfattning : Automotive climate systems use energy to achieve thermal comfort for the vehicle passengers. This energy use affects vehicle fuel consumption. The objectives of this thesis are to understand the energy use of automotive climate systems and investigate the effect of different energy saving measures.The research was conducted in several steps.

17. Logistic Time Requirements in Fast Sea Transportation Systems
Sammanfattning : The dissertation deals with logistic time requirements in fast sea transportation systems and the benefit of the application of the total time definition. The transportation engineering approach, to create new transport systems with high effectiveness, high service levels and also with high resource utilisation, has to some extent gained acceptance in the transportation industry, but it has not been fully realised that the transport system and the traffic system are not identical and that by focusing on high performance of the traffic system no guarantee is given that the transport system will become effective.

19. The Role of Plug-in Hybrid Electric Vehicles in Electrifying Personal Transport - Analysis of empirical data from North America
Sammanfattning : Plug-in hybrid electric vehicles (PHEV) can help reduce the greenhouse gas emissions in the transport sector, combined with the decarbonization of the electricity sector, and play an important role in electrifying personal transport. This thesis uses empirical data from North America to investigate the role of PHEVs in electrifying personal transport, with a focus on the household context and charging behavior. LÄS MER
20. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction
Sammanfattning : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. LÄS MER
