Comprehensive investigation of using n-butanol/gasoline blends in a port-fuel injection spark-ignition engine

摘要

In this study, butanol was examined mixing with gasoline at different ratios (Bu0, Bu5, Bu10, Bu20, and Bu30) in a single-cylinder, four-stroke, PFI SI engine for monitoring engine characteristics at various loads to perform thermodynamic analyses. It can be reported that the maximum efficiencies were calculated at the highest load for tested fuels. Accordingly, the maximum thermal efficiencies were computed to be between 35.85-40.60 meanwhile corresponding exergetic efficiency results were found to be between 33.33-37.85 for tested fuel samples. In addition, the maximum SIN values were achieved between 1.500-1.609.
