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.

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.

Get Peak Performance from Two-Stroke Engines Do you spend more time trying to start your weed trimmer than you do enjoying your backyard? With this how-to guide, you can win the battle with the temperamental two-stroke engine. Written by long-time mechanic and bestselling author Paul Dempsey, Two-Stroke Engine Repair & Maintenance shows you how to fix the engines that power garden equipment, construction tools, portable pumps, mopeds, generators, trolling motors, and more. Detailed drawings, schematics, and photographs along with step-by-step instructions make it easy to get the job done quickly. Save time and money when you learn how to: Troubleshoot the engine to determine the source of the problem Repair magnetos and solid-state systems--both analog and digital ignition modules Adjust and repair float-type, diaphragm, and variable venturi carburetors Fabricate a crankcase pressure tester Fix rewind starters of all types Overhaul engines--replace crankshaft seals, main bearings, pistons, and rings Work with centrifugal clutches, V-belts, chains, and torque converters

This book addresses the two-stroke cycle internal combustion engine, used in compact, lightweight form in everything from motorcycles to chainsaws to outboard motors, and in large sizes for marine propulsion and power generation. It first provides an overview of the principles, characteristics, applications, and history of the two-stroke cycle engine, followed by descriptions and evaluations of various types of models that have been developed to predict aspects of two-stroke engine operation.

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.

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.

A reference book of math equations used in developing high-performance racing engines, including calculating engine displacement, compression ratio, torque and horsepower, intake and header size, carb size, VE and BSFC, injector sizing and piston speed. --book cover.

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.
