Paperback. Zustand: New. Print on Demand. Building upon the invention of the small, high-speed petrol engine by Gottlieb Daimler, this book charts the development of internal-combustion engines, with a focus on aero engines. The author compares the weight and power output of the latest aero engines with large, heavy, and inefficient external-combustion engines from earlier periods to show the advantages of modern technology. The theoretical principles of engine cycles are delved into, prominently featuring the Carnot cycle and the four-stroke cycle. Calculations are performed for each to provide thermal efficiency figures, with the differences between the two cycles highlighted. Further analysis centers on the four-stroke cycle, including helpful explanatory diagrams. The author investigates the impact of the compression ratio on the thermal efficiency, explaining that while increased compression should theoretically increase efficiency, real-world engines often experience diminishing returns and even efficiency loss due to heat loss to the combustion chamber walls. The book concludes with an examination of factors affecting an engineâs performance, such as dissociation at high temperatures, loss of heat to metal walls, and incomplete combustion. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
