Combustion Engines Development nowadays is based on simulation, not only of the transient reaction of vehicles or of the complete driveshaft, but also of the highly unsteady processes in the carburation process and the combustion chamber of an engine. Different physical and chemical approaches are described to show the potentials and limits of the models used for simulation.

Univ.-Prof. Dr.-Ing. habil. Günter P. Merker was born in Augsburg/Germany in 1942. He studied mechanical engineering at the Technical University in Munich and received his diploma in 1969. He worked than as an assistant lecturer at this Institute and got his PhD in 1974 with a thesis on free convection problems. From 1975 to 1976, he has been as a research fellow at the Californian Institute of Technology in Pasadena/CA. Having returned to the Munich Technical University, he qualified as a university lecturer in 1978. From 1978 to 1980, he was with MTU GmbH in Munich. In 1980 he accepted an associate professorship for refrigeration technology at the University of Karlsruhe. In 1986 he started work at MTU Friedrichshafen, where he was head of the department analytics and engine calculation. In 1994 he accepted a full professorship for combustion engines at the University of Hannover. There he was head of the Institute of Technical Combustion until he retired in 2005. He was adviser to 43 PhD students. He is editor and co-editor of more than 140 technical scientific publications as well as six technical books on thermal transmission, fluid mechanics and combustion engines. He is a member of the Scientific Association in Braunschweig as well as of different technical committees. In addition to that, he works as an independent adviser for engine manufactories and service industries. Apl. Prof. Dr.-Ing. habil. Christian Schwarz was born in Regensburg in 1964. From 1983 to 1988, he studied mechanical engineering at the Munich Technical University. From 1989 to 1993, he worked as an assistant lecturer at the chair of internal combustion engines and vehicles at the Munich Technical University (Prof. Woschni). During that time he worked on unsteady, 0-dimensional process calculation for charged and quickly working diesel engines and got his PhD in 1993 on his thesis Simulation of the transient reaction of charged diesel engines during operation. Still at the sameuniversity, he was head of a team that worked on a part of the EU research project Hybrid Zero Emission Mobility (1993 to 1997). In 1998 he qualified as a university lecturer, his treatise was on Theory and Simulation of Charged Combustion Engines. He was appointed private lecturer by the University of Hannover in 1999, and he got the venia legendi in combustion engines. Since then he has been teaching the subject simulation of processes in combustion engines. In 2004 the Hannover University conferred him the title apl. Prof.. In 1997 he started work in the department for advance development at BMW AG. In 2001 he was appointed head of this department and was responsible for the development of new combustion techniques for spark ignition (SI) engines, such as direct hydrogen ignition, as well as of new concepts for charged SI engines. Since 2004 he has been working in series development, being responsible for the development of combustion techniques of the SI engines produced in series. He has supervised several dissertations on combustion engines. Besides, he is the author and co-author of several publications and lectures, as well as of a technical book about combustion techniques and the charging of combustion engines. In the research association about internal combustion engines, he is head of the planning team for total processes, and he is also part of its scientific advisory board.Dr.-Ing. Rüdiger Teichmann was born in Nordhausen in 1960. He studied mechanical engineering at the Technical University Dresden from 1982 till 1987. After his study he became a research student and a scientific staff member till 1990. In 1991 he got his PhD with a thesis on combustion development for truck diesel engines.
In the same year he started his professional carrier in the department for advance development at BMW AG in Munich. His special fields of work were thermodynamic, combustion development, load exchange for gasoline engines andcalibration in series development as well. In 1999 he became the head of product management for the complete indicating measurement chain at AVL List GmbH in Graz. After 3 years he was nominated as segment leader Indicating Measurement and global business segment leader for Combustion Measurement in 2005. In addition to this responsibility he is in charge of the vehicle measurement activities from AVL since 2007. Mr. Teichmann is author and co-author of several publications and tutor of diploma thesis.
