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.

Engine-tuning expert A. Graham Bell steers you through the various modifications that can be made to coax maximum useable power output and mechanical reliability from your two-stroke. Fully revised with the latest information on all areas of engine operation, from air and fuel, through carburation, ignition, cylinders, porting, reed and rotary valves, and exhaust systems to cooling and lubrication, dyno tuning and gearing.

This informative publication is a hands-on reference source for the design of two-stroke engines. The state-of-the-art is presented in such design areas as unsteady gas dynamics, scavenging, combustion, emissions and silencing. In addition, this comprehensive publication features a computer program appendix of 28 design programs, allowing the reader to recreate the applications described in the book. The Basic Design of Two-Stroke Engines offers practical assistance in improving both the mechanical and performance design of this intriguing engine. Organized into eight information-packed chapters, contents of this publication include: Introduction to the Two-Stroke Engine Gas Flow Through Two-Stroke Engines Scavenging the Two-Stroke Engine Combustion in Two-Stroke Engines Computer Modelling of Engines Empirical Assistance for the Designer Reduction of Fuel Consumption and Exhaust Emissions Reduction of Noise Emission from Two-Stroke Engines

In this well established book, now brought up to date in a second edition, the Technical Editor of `Performance Bikes' shows you how to evaluate your engine, how to assess what work you can undertake yourself, and what is best left to a specialist. The great attraction of the two-stroke is its enormous potential, contrasted with its appealing simplicity. Armed with little more than a set of files, you can make profound changes to the output power of a two-stroke. But these changes will increase the power only if you know what you are doing. `Motor Cycle Tuning (Two-stroke)' will therefore guide you through the necessary stages which can enable a stock roadster engine can be turned into a machine capable of winning open-class races, for an outlay which is positively low by racing standards. Very few other books on engine development and most of these are either devoted to car engines or are out of date Promoted by PERFORMANCE BIKES

Design and Simulation of Two-Stroke Engines is a unique hands-on information source. The author, having designed and developed many two-stroke engines, offers practical and empirical assistance to the engine designer on many topics ranging from porting layout, to combustion chamber profile, to tuned exhaust pipes. The information presented extends from the most fundamental theory to pragmatic design, development, and experimental testing issues. Chapters cover: Introduction to the Two-Stroke Engine Combustion in Two-Stroke Engines Computer Modeling of Engines Reduction of Fuel Consumption and Exhaust Emissions Reduction of Noise Emission from Two-Stroke Engines and more

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.

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.

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.

Tuning engines can be a mysterious art, all engines need a precise balance of fuel, air, and timing in order to reach their true performance potential. Engine Management: Advanced Tuning takes engine-tuning techniques to the next level, explaining how the EFI system determines engine operation and how the calibrator can change the controlling parameters to optimize actual engine performance. It is the most advanced book on the market, a must-have for tuners and calibrators and a valuable resource for anyone who wants to make horsepower with a fuel-injected, electronically controlled engine.
