Excerpt from Harper's Gasoline Engine Book: How the Engine Is Made, How to Use It at Home, in Boats and Vehicles, an Elsewhere, and How to Keep It in Order It has made possible the aeroplane and the submarine, the automobile, the motorcycle, and the motor-boat. In factories, farms, and homes countless motors are in daily use, steadily and rapidly performing a thousand tasks that formerly required the slow and laborious work Of many hands. Gas engines even drive the great dynamos that flash unseen wireless messages across the broad Atlantic, while locomotives thunder across continents and steam ships plow the seas by means Of this same wonderful power. The modern gas motor is the simplest, strongest, and most compact power-producing device known to man, and yet not one person in a thousand has but a vague idea Of its principles or operation. The purpose of this book is to serve as a simple, practical, and complete guide for all those who own, use, or Operate gas and gasoline motors. In its preparation every effort has been made to do away with technical terms and names and to adapt the book to the requirements Of those who possess little or no knowledge Of engineering or mechanics.
