1. Towards sustainable urban transportation : Test, demonstration and development of fuel cell and hybrid-electric buses
Sammanfattning : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. LÄS MER
2. Fuel-Efficient Look-Ahead Control for Heavy-Duty Vehicles with Varying Velocity Demands
Sammanfattning : The fuel consumption of heavy-duty vehicles can be reduced by using information about the upcoming road section when controlling the vehicles. Most manufacturers of heavy-duty vehicles today offer such look-ahead controllers for highway driving, where the information consists of the road grade and the velocity only has small variations.

3. The Performance of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management
Sammanfattning : The prime mover in the world today is the Internal Combustion (IC) engine. The development and improvement of the internal combustion engines since Nicolaus August Otto and Rudolf Diesel has continued until today and will continue long into the future. No major competitor to the IC engine has yet emerged. LÄS MER
4. 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
