In 1988, he published a textbook, "Internal Combustion Engine Fundamentals", which served as a key text for mechanical engineering courses around the world and as an essential text for professional engineers in the field. The book sold over 130,000 copies, [1] with a second edition published in 2018. [3]
Rotary engines of the Wankel design are used in some automobiles, aircraft and motorcycles. These are collectively known as internal-combustion-engine vehicles (ICEV). [18] Where high power-to-weight ratios are required, internal combustion engines appear in the form of combustion turbines, or sometimes Wankel engines.
To overcome the low efficiency of steam and combustion engines of the time, Diesel wanted to build an entirely new type of internal combustion engine. [10] In the 1890s, regular gas engines were capable of transforming only 6% of the fuel energy into kinetic energy; [ 11 ] good triple expansion steam engines were slightly better than that, they ...
Engines: Man's Use of Power, from the Water Wheel to the Atomic Pile is a science book for children by L. Sprague de Camp, illustrated by Jack Coggins, published by Golden Press as part of its Golden Library of Knowledge Series in 1959. [1] [2] [3] A revised edition was issued in 1961, and a paperback edition in 1969.

Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
Brayton engines used a separate piston compressor and piston expander, with compressed air heated by internal fire as it entered the expander cylinder. The first versions of the Brayton engine were vapor engines which mixed fuel with air as it entered the compressor; town gas was used or a surface carburetor was also used for mobile operation . [3]
The efficiency of internal combustion engines depends on several factors, the most important of which is the expansion ratio. For any heat engine the work which can be extracted from it is proportional to the difference between the starting pressure and the ending pressure during the expansion phase. Hence, increasing the starting pressure is ...
