The extensive experience of Engines PdM's founders - Prof. Eran Sher and Dr.Gal deBotton - enabled them to develop the new vibration analysis system for internal combustion engines. For many years these two scientists have been involved in research on I.C. engines and analysis of vibrations of mechanical systems.

Eran Sher is Professor of Mechanical Engineering at Ben-Gurion University of the Negev. He was responsible for the establishmant of the Internal Combustion Engines Teaching and Research Laboratory. Prof. Sher's teaching and research interests focus on the area of thermal sciences, particularly the operating characteristics and technologies of pollution reduction in automotive and two-stroke engines. He is editor of the Handbook of Air-Pollution from Internal Combustion Engines, author of an introductory textbook for undergraduates entitled Internal Combustion Engines, and co-author of a fundamental text, The Two-Stoke Cycle Engine. Other published works include over 120 scientific articles and more than 140 papers that have been presented at international conferences. Prof. Sher has also successfully developed various products that are now commercially available. In 1989, Prof. Sher received the John Orr award for "Leading Research in Mechanical Engineering", and, in 1995, the Bergman award for "Outstanding Scientific Achievements".

Dr. Gal deBotton is Senior Lecturer in the Department of Mechanical Engineering at Ben-Gurion University of the Negev. In 1993, he received his Ph.D. degree from the Department of Mechanical Engineering and Applied Mechanics at the University of Pennsylvania. His primary research work is concerned with the study of the mechanical behavior of materials and structures. Dr. deBotton established the Solid Mechanics Laboratory where, among other research topics, non-destructive-testing methods for solid structures through the application of vibration analysis techniques, are being investigated. He is a member of the Vibration Institute, an internationally recognized organization dedicated to the exchange of practical information about vibration and condition monitoring, and he is recognized for the significant contribution he has made in this field.

The Internal Combustion Engines Laboratory

The Internal Combustion Engines Laboratory at Ben-Gurion University was established in 1978, and laboratory members immediately became involved in a wide range of R&D projects. Most of these projects are sponsored by various industries located in Germany, the UK, Switzerland, and the USA, as well as by the Israeli government (the Ministries of Defense, Commerce, Environment, and Science). The diverse range of projects carried out in the laboratory include the development of RPV engines, Sulzer large-bore 2-S engines, Karl-Schmidt small engines, and various auxiliary systems (such as ignition, fuel injection and catalysts). Six faculty members, five doctoral students, and twelve M.Sc. students staff the laboratory.

Many of the research projects have been performed collaboratively with well-known research groups in the world, including those from MIT, UMIST, Imperial College, Univ. Erlangen-Nurnberg, Darmstadt, and Carnegie-Mellon University.

During the last twenty years of intensive research, the members of the I.C.E. laboratory have published over 200 scientific and technical papers in some of the most highly prestigious scientific journals, including those of the SAE. The members have also participated in numerous worldwide international conferences. In addition, laboratory research has yielded a textbook for undergraduate students entitled, Introduction to ICE (Michlol, 1991); a Handbook on Air-Pollution from Internal Combustion Engines (Academic Press,1988); and a book specializing in two-stroke engines, The Two-Stroke Cycle Engine - Its Development, Operation and Design (a joint publication of Taylor and SAE, 1999). In 1995, the Israeli government recognized the laboratory as a "center of excellence".

Present ongoing research programs in the laboratory include:

  • Vibration monitoring as a predictive maintenance tool for reciprocating engines;
  • Development of pulsed corona discharge technology for pollution control;
  • Ignition and flame initiation in spark-ignition engines;
  • Fuel atomization by flash-boiling, air-assisted, and effervescent concepts;
  • Strategy considerations for variable valve timing in unthrottled SI engines;
  • High altitude performance of a small-size two-stroke engine for RPV's applications.
