This book explores diesel engines used in various modes of transport. The famous American writer Mark Twain once wrote, "The reports of my death are greatly exaggerated." To paraphrase his statement, we could say, "The reports of diesel engines' death are greatly exaggerated." Indeed, there is currently a steady trend toward the use of electric motors. However, firstly, a sufficient amount of stored electricity is necessary, and renewable energy sources are currently insufficient. Secondly, diesel engine developers are constantly developing new engine designs that are more cost-effective, more environmentally friendly, and offer a number of other advantages. This book is devoted to the latest developments in the use of diesel engines, their new designs, technological aspects of their use, related environmental issues, and other relevant information. The book's strength lies in its comprehensive approach to the issue, analyzing it from various perspectives by scientists representing different countries and holding diverse approaches. Thus, the book can be characterized as a single-themed scientific monograph, designed to inform the public about the achievements of scientists from eight countries. This book is intended for scientists, teachers, and students. It can also be recommended to a wider audience interested in the various applications of engines in the transportation industry and the achievements of modern science in various countries.
