**Meet the editors**

Professor Kazimierz Lejda graduated in mechanical engineering in 1971 from Cracow University of Technology where he also earned his PhD degree in internal combustion engine engineering in 1983. In 1993 he obtained a postdoctoral qualification from Kiev Institute of Vehicles and Roads (Ukraine) within automotive vehicle and combustion engine engineering. He has stayed

employed in Rzeszów University of Technology since 1973; he got the chair of Department of Automotive Vehicles and Internal Combustion Engines in 1994, and was honoured with professorship in 2011. His scientific interests cover development of injection systems for greening engines and improving their performances. Prof. Lejda is a member of Polish Academy of Sciences and other domestic and international scientific organizations, and is a very prolific industrial and scientific researcher and publisher; he has drawn up more than 365 items including 7 books. He also reveals great contribution to young scientists' and engineers' education.

Paweł Woś is an assistant professor in Rzeszów University of Technology, where he graduated in mechanical engineering in 1995, and earned his PhD degree in combustion engine engineering in 2003. Within 2005 to 2006 he served as a post-doc fellow in Wayne State University in Detroit (USA) where he worked on advanced combustion processes in ICE. He continues the studies with ap-

plication of variable compression ratio (VCR) technology. He is the author of more than 45 papers and scientific reports.

## Preface

Internal combustion engines (ICE) are the main sources of powering for almost all road vehicles, yet many other machines too. Being under strength development for a number of years, they have already reached a relatively high level of technical excellence and now they also produce acceptable output parameters. Still, they are not devoid of drawbacks. Harmful exhaust emissions can be pointed as the most important here. This problem is the main focus of interest for automotive researchers and engineers. Continuous decrease of exhaust emission limits additionally intensifies their efforts to produce more green engines and vehicles. On the other hand, rapid development of road transportation and the growth of end-users' demands toward more and more comfortable, durable, reliable and fuel-saving vehicles unceasingly calls for improvements in engine design and technology.

Despite many attempts, replacing the internal combustion engine with other, but equally effective power source still fails. Therefore, extensive works on the improvement of internal combustion engines should be carried out and the results need to be widely published.

As the answer to above expectations, this book on internal combustion engines brings out few chapters on the research activities through the wide range of current engine issues. The first section groups combustion-related papers including all research areas from fuel delivery to exhaust emission phenomena. The second one deals with various problems on engine design, modeling, manufacturing, control and testing. Such structure should improve legibility of the book and helps to integrate all singular chapters as a logical whole.

We wish to thank InTech Publisher and are especially pleased to express same thanks to Ms. Viktorija Žgela for giving us an invitation and opportunity to be editors of the book on internal combustion engines. Distinctive thanks are also due to Ms. Romana Vukelić and Ms. Marina Jozipović, and Publishing Process Staff for their help in coordinating the reviews, editing and printing of the book.
