1. Model-Based Control of Gasoline Partially Premixed Combustion
Sammanfattning : Partially Premixed Combustion (PPC) is an internal combustion engine concept that aims to yield low NOx and soot emission levels together with high engine efficiency. PPC belongs to the class of low temperature combustion concepts where the ignition delay is prolonged in order to promote the air-fuel-mixture homogeneity in the combustion chamber at the start of combustion.

3. Turbo Charged Low Temperature Combustion - Experiments, Modeling and Control
Sammanfattning : Both the global economy and the society in general are dependent on the availability of reliable transportation. Most transportation technology involves the use of internal combustion engines in one way or another. LÄS MER
4. Design and Optimization of In-Cycle Closed-Loop Combustion Control with Multiple Injections
Sammanfattning : With the increasing demand of transportation, biofuels play a fundamental role in the transition to sustainable powertrains. For the increased uncertainty of biofuel combustion properties, advanced combustion control systems have the potential to operate the engine with high flexibility while maintaining a high efficiency and robustness.

5. 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.
