Fuel Impacts (E0 x E100) on the Acoustic Performance of Exhaust Systems 2017-36-0084
Currently in Brazilian market we have application of two different fuels in large scale, gasoline with addition of 27% of hydrous ethanol, otherwise known as ethyl alcohol or alcohol and pure hydrous ethanol. These different fuels and their various blends combinations - from 27% (E27) to 100% (E100) of ethanol - make the gases from combustion have different physical characteristics, affecting directly the exhaust system acoustic performance. This study is going to describe the physical differences of the exhaust gases with various blends combination and their respective impact on the exhaust system acoustic performances.
