This book presents, in a clear and easy-to-understand manner, the basic principles involved in the design of high performance engines. Editor Joseph Harralson first compiled this collection of papers for an internal combustion engine design course he teaches at the California State University of Sacramento. Topics covered include: engine friction and output; design of high performance cylinder heads; multi-cylinder motorcycle racing engines; valve timing and how it effects performance; computer modeling of valve spring and valve train dynamics; correlation between valve size and engine operating speed; how flow bench testing is used to improve engine performance; and lean combustion. In addition, two papers of historical interest are included, detailing the design and development of the Ford D.O.H.C. competition engine and the coventry climax racing engine.

This compendium is an update to two best-selling editions published by SAE International in 1995 and 2003. Editor Doug Fehan has assembled a collection of technical papers from the SAE archive that will inspire readers to use race engine development as an important tool in the future of transportation. He focuses on several topics that are important to future race engine design: electrification, materials and processes, and improved technology. Today’s electric hybrid vehicles and kinetic energy recovery systems embody what inventors envisioned in the early 1900s. First employed in trams and trains of that era, the technology was almost forgotten until racers resurrected their version in 2009 F-1 racing. The automotive industry has long admired the aircraft industry’s use of lightweight metals, advanced finishing processes, and composites. The use of these materials and processes has helped reduce overall mass and, in turn, improved speed, performance, and reliability of race engines. Their initial high cost was a limiting factor for integrating them into mass-produced vehicles. With racing leading the way, those limitations were overcome and vehicles today feature some amazing adaptations of those processes and materials. Engine power, efficiency, durability, reliability, and, more recently, emissions have always been of primary importance to the automotive world. The expanding use of electrification, biofuels, CNG, high-pressure fuel delivery systems, combustion air management, turbocharging, supercharging, and low-viscosity lubricants have been the focus of race engine development and are now turning up in dealer showrooms. The papers in this publication were selected for two reasons: they demonstrate the leadership that racing plays in the future of automotive engineering and design as it relates to engines; and they will be interesting to everyone who may be in racing and to those who may want to be in racing.

A reference book of math equations used in developing high-performance racing engines, including calculating engine displacement, compression ratio, torque and horsepower, intake and header size, carb size, VE and BSFC, injector sizing and piston speed. --book cover.

The 53 technical papers in this book show the improvements and design techniques that researchers have applied to performance and racing engines. They provide an insight into what the engineers consider to be the top improvements needed to advance engine technology; and cover subjects such as: 1) Direct injection; 2) Valve spring advancements; 3) Turbocharging; 4) Variable valve control; 5) Combustion evaluation; and 5) New racing engines.

The needs of a true competition engine are quite different than those of the engine under the hood of a typical commuter car. From the basic design needs, to the base component materials, to the sizes of the flow-related hardware, to the precision of the machining, to the capabilities of each pertinent system, very few similarities exist. Many books exist showcasing how to make street-based engines more powerful and/or durable. This book is different, in that it focuses purely on the needs of high rpm, high durability, high-powered racing engines. It begins by looking at the raw design needs, and then shares how these needs are met at the various phases of an engine's development, assembly, testing and tuning. This book features reviews of many popular modern tools, techniques, products, and testing/data collecting machinery. Showing the proper way to use such tools, how to accurately collect data, and how to use the data effectively when designing an engine, is critical information not readily available elsewhere. The special needs of a competition engine aren't commonly discussed, and the many secrets competition engine builders hold closely are openly shared on the pages here. Authored by veteran author John Baechtel, Competition Engine Building stands alone as a premier guide for enthusiasts and students of the racing engine. It also serves as a reference guide for experienced professionals anxious to learn the latest techniques or see how the newest tools are used. Baechtel is more than just an author, as he holds (or has held) several World Records at Bonneville. Additionally, his engines have won countless races in many disciplines, including road racing and drag racing.

This authoritative book, elegantly written in highly digestible style by the foremost expert on the subject, provides in-depth analysis of classic motorcycle race engines spanning eight decades, from the 1930s Guzzi 500 120-degree twin to the latest Yamaha YZR M1 in-line four. Packed with technical detail, the book provides an absorbing insight into the technology employed in a wide variety of motorcycle engines, investigating the diverse approaches taken by various manufacturers over the years in the search for race-winning performance.

Extracting maximum torque and horsepower from engines is an art as well as a science. David Vizard is an engineer and more aptly an engine building artist who guides the reader through all the aspects of power production and high-performance engine building. His proven high-performance engine building methods and techniques are revealed in this all-new edition of How to Build Horsepower. Vizard goes into extreme depth and detail for drawing maximum performance from any automotive engine. The production of power is covered from the most logical point from the air entering the engine all the way to spent gasses leaving through the exhaust. Explained is how to optimize all the components in between, such as selecting heads for maximum flow or port heads for superior power output, ideal valvetrain components, realizing the ideal rocker arm ratios for a particular application, secrets for selecting the best cam, and giving unique insight into all facets of cam performance. In addition, he covers how to select and setup superchargers, nitrous oxide, ignition and other vital aspects of high-performance engine building.
