Small Gas Engines 12e, Online Textbook
Small Gas Engines, a recommended textbook by the Equipment & Engine Training Council (EETC), is a student-focused approach to learning that starts with the basics—safety, tools, fasteners, and electrical fundamentals—and progresses logically through the design, operation, troubleshooting, and repair of small engines. It applies to a wide range of engine designs from different manufacturers and covers all areas of engine theory and service, with extensive information on L-head, overhead valve, and overhead cam engine designs. The book provides a sound understanding of the science involved in four-stroke and two-stroke internal combustion cycles and clear explanations of the role of basic engine components, the benefits and operation of various engine designs, and up-to-date emission control information. The Applications Unit includes information about a wide range of small engine applications, such as lawn equipment, lawn tractors, snow throwers, and more.
