This text is designed as a bridge between the instructor's lectures and the information furnished by the engine manufacturer. The service manuals, offered by the engine manufacturers, are filled with information that is very specific and indispensable when servicing engines, but the beginning technician has difficulty utilizing them. - Preface.

This second edition of this text expands and updates its already thorough coverage of the operation, maintenance and repair of small, air-cooled gas engines. It features new chapters on failure analysis, and starter systems, as well as a rewrite of the electrical chapter to include feedback systems and fuel injection. An expansion of the carburation chapter includes new carburetors including cab 1 carburetors. This text is now accompanied by a comprehensive competency-based workbook.

From the Back Cover: Power Equipment Engine Technology (PEET) is a comprehensive textbook that is designed to meet the basic needs of readers interested in the subject of small engine repair, and to help students become more qualified candidates for shops looking for well-prepared, entry-level technicians. PEET contains 17 chapters, beginning with a brief history of the internal combustion engine and ending with a chapter on troubleshooting various conditions found on any power equipment engine. Also, both two-stroke and four-stroke engines are covered. This book has been written to make the learning experience enjoyable, with easy-to-read-and-understand chapters and over 600 illustrations to assist visual learners with content comprehension. PEET can be used not only by pre-entry-level technicians but also as a reference manual by practicing technicians, and it will be helpful for the general consumer of power equipment engines that has an interest in understanding how they work. Power equipment technicians are currently sought after and will continue to be in demand in the future as technology advances in the manufacturing of modern power equipment engines.

This Final Report has been prepared by AlliedSignal Engines and Systems, Phoenix, Arizona, documenting work performed during the period May 1997 through June 1999, under the Small Engines Technology Program, Contract No. NAS3-27483, Task Order 13, ANOPP Noise Prediction for Small Engines. The report specifically covers the work performed under Subtasks 4, 5 and 6. Subtask 4 describes the application of a semi-empirical procedure for jet noise prediction, subtask 5 describes the development of a procedure to predict the effects of wing shielding, and subtask 6 describes the results of system studies of the benefits of the new noise technology on business and regional aircraft.
