Study on the Exhaust System Parameters of a Small Gasoline Engine 2008-01-1766

Intake and exhaust systems are significant components of an internal combustion engine. The design and operational variables of intake and exhaust systems are decisive to determine overall engine performance. The best engine overall performance can be obtained by proper design of the engine intake and exhaust systems. The intake system parameters have been studied by numerous researchers. Therefore, this paper pays attention to the exhaust system parameters. The effects of exhaust pipe length and exhaust valve timing on the performances of engine are investigated. The results demonstrate that the exhaust pipe length and exhaust valve timing exert great influences on the engine efficiency, volumetric efficiency, mean pressure loss for gas exchange, etc.
