Internal-Combustion Engine Induction and Exhaust System Noise

Abstract

The importance of induction and exhaust systems on community and passenger noise exposure and engine performance are introduced. Discussion is given of the types of engines and induction/exhaust systems they use. They include naturally aspirated two- and four-stroke engines, supercharging, turbocharging, and a special discussion on the similarities and differences between the Wankel engine, rotary engine, and others. The effects of mufflers on engine performance and their noise reduction capabilities are discussed.
