Experimental and Computational Analysis of a High Performance Four-Stroke Motorcycle Engine Equipped with a Variable Geometry Exhaust System 2002-01-0001

The application of computational methods for the development of a high performance four-stroke motorcycle engine has here been evaluated. A single dimension fluid dynamic code has been employed to simulate engine performance at full load, and data predicted from computer simulation have been compared with experimental results.
After the abovementioned validation process, computer simulation techniques were applied to develop a variable geometry exhaust system so as to optimize volumetric efficiency over a wider speed range. These techniques proved to be powerful and effective in the identification of the modifications required to obtain the engine performance targets.
