1. Active Stabilization of Thermoacoustic Oscillation
Sammanfattning : Combustion processes serve as important sources of energy for both power generation and for transport, ranging from large scale power stations to micro turbines and aeroplane engines. Lean premixed combustion offers a potential to reduce the emission levels, but suffers from instability problems which can be overcome by the use of active control. LÄS MER
2. 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
3. HCCI Operation - Closed loop combustion control using VVA or dual fuel
Sammanfattning : The current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. LÄS MER
4. Model-Based Optimization of Combustion-Engine Control
Sammanfattning : The work presented in this thesis is motivated by the need to reliably operate a compression-ignition engine in a partially premixed combustion (PPC) mode. Partially premixed combustion is a low temperature combustion concept, where the ignition delay is prolonged to enhance fuel-air mixing in the combustion chamber before the start of combustion.

5. Towards Energy Efficient Control of Individual Wheel Drive Articulated Vehicles
Sammanfattning : The aim of this thesis was to increase knowledge in the area of articulated vehicles and specifically energy efficient traction control. Eletrical propulsion of vehicles has started to be popular due to its versatility and freedom of design. LÄS MER
