POWER AND PROPULSION
−− Spray-wall interactions −− Cold start and wall wetting issues • Combustion Process and Control Strategies
engines for series including Formula One, Indy Cars, the IRL, and NASCAR. This course will help you determine how to design a champion- ship-winning racing engine including many of the key calculations that support the pursuit of power. Attention to detail on every aspect of engine design is emphasized with focus on applying simple math, physics, and even plain old common sense, rather than relying heavily on sophisticated software. The course begins with a review of the major advances in engine design , then explores the design of the engine’s primary systems and structures including oil systems, cam drive systems, water systems, inlet systems, exhaust systems, cylinder heads, cylinder blocks, and sumps. It will then explore how combustion works and how to analyze the major parameters involved in burning different fuels. This will be followed by the design and optimization of inlet and exhaust systems and applying mathematics via simple excel spread sheets to determine the key factors for cam design, port design, inlet and exhaust tuning, and turbocharger / supercharger matching for those formulae that permit the use of boost to increase the inlet pressure. The day concludes with a discussion and opportunities to continue design exercises that will allow attendees to put into practice several of the key concepts learned throughout the seminar. Detailed course notes and illustrations are provided along with example calculations to enable the attendee to calculate the key parameters required in the design and development of racing engines. Learning Objectives By attending this seminar, you will be able to: • Describe the key parameters and choices facing the high performance engine designer • Consider a variety of tips and solutions which can be applied by both design and development engineers to enhance the performance of competition engines • Select “the least worse design solution” for any particular problem • Summarize the major advances in engine design over the past 40 years Who Should Attend This course is for individuals with a thirst to improve their understanding of what makes a racing engine a championship winner. It can be valuable to those responsible for engine design, component design, and overall engine performance calculations or those who are merely interested in the subject. Prerequisites An undergraduate engineering degree or a strong automotive technical background is highly recommended. A basic knowledge of college algebra, college physics, and a familiarity with how we currently think engines work is helpful.

High Performance Engine Design and Development 1 Day | Classroom (Available for Private Delivery Only) I.D.# C0725 Ever since Beau de Rochas patented the four stroke cycle in 1862, engineers have pursued the development of high performance engines for road and racing applications at an accelerated pace. While this course will not cover such ancient history, it will focus on engine design and development advances over the last 40 years from “BC to AD” (“Before Cosworth to After Duckworth”), covering the concepts and designs behind the modern racing
