Design and Simulation of Two-Stroke Engines discusses principles of automotive design which are specific to this engine type. The book includes new theories developed by the author that have never been published before, particularly on: unsteady gas flow in engine ducting scavenging flow within the cylinder two-zone combustion to compute exhaust emissions computation of intake and exhaust sound pressure levels discharge coefficients of ports and valves. Design and Simulation of Two-Stroke Engines is a unique hands-on information source. The author, having designed 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 fundamental theory to pragmatic design and experimental testing issues.
