Motors

A practical, illustrated manual for young readers that explains the principles and devices used to produce and apply mechanical power. It begins with basic concepts of energy, motion and resistance, then surveys water, steam and internal-combustion motors, boilers and turbines, and the fuels and combustion processes that drive them. Chapters describe carburetors, low- and high-tension ignition systems, and essential mechanical components such as valves, cams, gears and governors, with guidance on measuring and transmitting power. The volume concludes with discussions of special engine types, refrigeration and the role of power in transportation and industry.
