Gas and Petroleum Engines

Gas and Petroleum Engines is a 1898 translation of a work by Frenchman Henry De Graffigny. The book follows the format of several texts of the time, except this one is lighter on theory and goes into details of multiple specific engines. Included is a brief history of the gas engine, which, unfortunately, is not illustrated. It then goes into a section on gas engine theory, after which it jumps into descriptions of specific engines available at the time. Since it was originally written in France and translated in England, the engines are all of European origin. Engines include Lenoir's 4 cycle engine, Benier, Forrest, Martini, Charon, DeDion, Grob, and Hornsby-Akroid, to name a few. Also included is a list of engines tested and the results, and a chapter on gas producers. The illustrations are small, but still retain most of the detail.
