The Wankel rotary engine has long been an object of fascination and more than a little mystery. A remarkably simple design (yet understood by few), it boasts compact size, light weight and nearly vibration-free operation. This complete and well-illustrated account traces the full history of the engine and its use in various cars, motorcycles, snowmobiles and other applications. It clearly explains the working of the engine and the technical challenges it presented--the difficulty of designing effective and durable seals, early emissions troubles, high fuel consumption, and others. 978-0786429059 18 years + 1 pound 7 x 0.37 x 10 inches 182 pages McFarland & Company Softcover#50, printed on alkaline paper Cover photo: Felix Wankel with DKM125 prototype of 1957
