This fully revised and updated edition is one of the most comprehensive references available to engine tuners and race engine builders. Bell covers all areas of engine operation, from air and fuel, through carburation, ignition, cylinders, camshafts and valves, exhaust systems and drive trains, to cooling and lubrication. Filled with new material on electronic fuel injection and computerised engine management systems. Every aspect of an engine's operation is explained and analyzed.







High Performance Two-Stroke Engines


Book Description

High Performance Two-Stroke Engines analyses the technology of spark ignition two-stroke engines. The presentation is simple and comprehensive. The description of the operating cycle, the fluid dynamics, the lubrication and the cooling systems is followed by painstaking analysis of the mechanical organs, with the materials and the manufacturing processes employed to produce them. The book is completed by an overview of the history and evolution of these engines and by an examination of the principal types and the diverse fields in which they are employed. A section of the work is dedicated to an in-depth analysis of the ignition and combustion phases and the formation of the air-fuel mixture, with particular attention paid to the most recent injection systems.

Author Dave Boothroyd covers the principles and practice of two-stroke engine work, examining a wide range of marques and road, racing and trail motorcycles. With over 450 colour photographs, this new book covers: the chronological development of two-stroke engines and workshop procedures for each era; the examination of each major engine component in turn, including cylinder head, piston, piston rings, crankcase, flywheel, bearings, inlet manifold, clutch, gearbox and primary drive, and, finally, racing motorcycles and tuning engines for best performance; diagnosing problems and workshop safety. This practical reference guide is for the two-stroke motorcycle owner or restorer and is illustrated throughout with over 450 colour photographs.




The High-Performance Two-Stroke Engine


Book Description

The two-stroke engine is widely used in both motorcycle racing and kart racing, and in very large numbers in model car, boat and aircraft competition. The mechanical simplicity of the two-stroke engine gives it tremendous appeal, and makes it a tempting target for tuning operations, but the key to successful design, development and modification is knowledge of the engine¿s operating principles. This in-depth technical study of two-stroke theory and practice is intended to help would-be engine tuners to better understand the engine and the processes taking place within it, and thereby to obtain improved performance.
