Prof. Dr.-Ing. Roland Baar, Head of the department of Powertrain
Technologies at Technische Universität Berlin, unfortunately deceased on
23 June 2018. Professor Roland Baar rendered an outstanding service to
the science of powertrain technologies, especially in the field of
turbocharging. His enthusiasm and determination were both a professional
and a personal inspiration to everyone who worked with him. To continue
Roland Baar’s work, his business and academic colleagues dedicate this
collection of scientific papers to his memory.
The articles in this memorial publication cover different aspects of
powertrain technology research. This topic plays an important part in
the current public debate on climate protection, air pollution control
The first articles of this book deal with the market situation and the
general framework for research and development of powertrains. This lays
the foundation for more technical topics.
The following articles are concerned with the growing trend of
powertrain electrification. They discuss the numeric modeling of
alternative drivetrains and the energetic assessment of different
powertrain concepts, such as hybrid drives and fuel cells.
One of the central topics in this book is the combustion engine, which
encompasses both the diesel and the gasoline engine. For instance, the
injection of water into gasoline engines is covered extensively as a
method to raise the thermodynamic efficiency. Furthermore, there are
articles on innovative injection concepts for diesel engines as well as
on the use of alternative, regenerative fuels for combustion engines.
Many of the articles address the subject of turbocharging of combustion
engines, which was a major research topic of Roland Baar. In the present
book, a special focus is on the analysis of energy flows and the
possibilities of a better modeling of charging units in numerical
The last part of the book contains articles on novel aftertreatments of
exhaust gases to reduce pollutant emissions as well as on experimental
methods in this field.
