Diese Dissertation ist auf den Internetseiten der Hochschulbibliothek online verfügbar. First and foremost I owe my deepest gratitude to my supervisor, Prof. Norbert Peters, who supported, encouraged and guided me throughout my thesis. He allowed me freedom to work on my own way, and he always found time for my questions. He has been a source of inspiration to my work. I am heartily thankful to Prof. Stefan Pischinger for his interest in my work and being the co-examiner of my doctoral examination committee, and to Prof. André Bardow for serving as chair of my doctoral examination committee. I am grateful to General Motors (GM) Company for providing the financial support within the framework of the Collaborative Research Laboratory (CRL) which is collaboration between GM and RWTH Aachen University. It was a great pleasure to work with the people from the Powertrain Systems Research Laboratory of the GM R&D Center in Warren in Michigan, who were always ready to help and support my research work. Especially, I am indebted to Dr. Ramachandra Diwakar for many fruitful discussions and his critical comments on my work. I would also like to thank my colleagues in the CRL from the University for their wonderful cooperation. A special thanks goes to Mr. Michael Rottmann from the Institute of Combustion Engines of the RWTH Aachen University for providing the experimental data. Aitor Chivite and Rahul Pardeshi for supporting my research work through their Mini or Master thesis. I would like to extend my thanks to all my current and former colleagues from my institute for their kind supports and the great time. Especially, I thank to I owe a lot to Günter Paczko, with whom I not only enjoyed my lunch breaks and discussions about everything, but he also contributed in many ways to my research work. His way of thinking has left a permanent impression on me. I would also like to thank him and Sonja Engels for their readiness and patience in correcting my German grammar mistakes. I thank my parents for educating me, for their unconditional support and encouraging me to follow my own path. Thanks to my sister and brother for their love and care. To Ewelina Sobierska goes the greatest " thank you " for believing in me and her continuing support. She has been a constant reminder to me that there are other more important things in life, through …

Modeling of injection-rate shaping in diesel engine combustion

The main combustion by-products of an automotive diesel engine are carbon-dioxide
(CO2), particulate matter (PM) and oxides of nitrogen (NOx). Engine designers are
challenged by the legal limits for PM and NOx reductions, especially as options are
limited. Exhaust after- treatment devices are being used as a means to meet emission
legislations. Another option, optimising the combustion process itself, has potential
for improved efficiency as well as reducing the regulated emission species. Studies
have confirmed this, by demonstrating that the in-cylinder flow conditions, which are
driven by fuel spray and piston bowl interaction, are critical for the combustion event.
Achieving emission reductions without compromising engine efficiency requires
improved understanding of fuel/gas mixing and pollutant formation mechanisms.
This improved understanding of the combustion system can be obtained through
mechanical, electrical/electronic and optical techniques. Optical techniques are often
preferred due to their non-intrusive nature.
