Book Description
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.

Book Description
Racing continues to provide the preeminent directive for advancing powertrain development for automakers worldwide. Formula 1, World Rally, and World Endurance Championship all provide engineering teams the most demanding and rigorous testing opportunities for the latest engine and technology designs. Turbocharging has seen significant growth in the passenger car market after years of development on racing circuits. Advances in Turbocharged Racing Engines combines ten essential SAE technical papers with introductory content from the editor on turbocharged engine use in F1, WRC, and WEC-recognizing how forced induction in racing has impacted production vehicle powertrains. Topics featured in this book include: Fundamental aspects of design and operation of turbocharged engines Electric turbocharger usage in F1 Turbocharged engine research by Toyota, SwRI and US EPA, Honda, and Caterpillar This book provides a historical and relevant insight into research and development of racing engines. The goal is to provide the latest advancements in turbocharged engines through examples and case studies that will appeal to engineers, executives, instructors, students, and enthusiasts alike.
Utilizing the Thermodynamic Properties of E85 to Increase the Specific Efficiency of a High Specific Output Single Cylinder Formula SAE Engine

Book Description
Formula SAE is a collegiate engineering competition that has participants from around the globe. Of the 1000 points available throughout the event, 100 (10%) are dedicated to the fuel efficiency of the student built race cars. Competition rules allow either gasoline or E85, a mix of 85% ethanol and 15% gasoline, to be used as the primary fuel source. Because of the reduced specific energy content of E85, scores are normalized by applying a 1.4 divider to the final consumed volume of E85. With the desire to earn more points, a quantifiable way to determine if E85 could be an advantage was needed. To measure fuel consumption on the race track where every gram added to the car matters, a way to characterize flow rate and dead time of the fuel injector in the car was devised by finding the static flow rate and the associated combination of opening and closing times, or dead time. The method devised was designed to be simple to perform and data analysis was automated to make post processing a simple matter of transferring flow rate and dead time numbers into the engine control unit. Data recorded on track at the Formula Student Germany 2013 event and on the Oregon State University engine dynamometer were compared, and a method to estimate fuel consumption on any recorded track from engine dynamometer data was created. The estimation was first compared with recorded results from competition with an error of 2.1%, indicating that the results were reasonable to use for different engine configurations. Engine data was recorded for E85 and run through the estimation to determine how much E85 fuel would have been required to run the same event. The estimation was also used to determine how much work was done on track by the engine, which is another indicator of total system efficiency. Four engine configurations were tested. The baseline engine was the configuration used in the 2013 Global Formula Racing car, consisting of a Honda CRF450X engine, 3.8 liter intake plenum, Bosch 945 fuel injector, 13.5:1 compression piston, and a Megacycle X2 camshaft. This configuration was running on gasoline. Configuration 2 switched to a Honda 16450-MEN-A51 fuel injector. Configuration 3 changed fuel from gasoline to E85. The last configuration increased the compression ratio to 14:1. Configuration 2 had the highest overall efficiency at 34%, with configuration 4 having the highest energy generation over the course of the FSG 2013 endurance at 29.4 MJ. After normalizing energy generation, configuration 4 required the least volume of fuel to complete endurance at 2.5 liters, a reduction from 2.7 liters that the baseline required. This resulted in an approximate point increase of about 4.4. While this is an increase in point, the was determined that it was not enough to justify the use of E85 at FSAE events due to increased procurement and handling difficulty, along with reduced engine starting reliability.
