Comparative assessment of ethanol and isobutanol addition in gasoline on engine performance and exhaust emissions

The depletion of fossil fuels is causing great concern and it is important to search for alternatives. Ethanol and isobutanol are suitable for spark ignition engine due to their favorable physicochemical properties that can be blended with pure gasoline to reduce the dependency on petroleum fuels. Six types of fuel blends consisting of ethanol and…

Performance and emission characteristics of a spark ignition engine fuelled with butanol isomer-gasoline blends

The heavy reliance on petroleum-derived fuels such as gasoline in the transportation sector is one of the major causes of environmental pollution. For this reason, there is a critical need to develop cleaner alternative fuels. Butanol is an alcohol with four different isomers that can be blended with gasoline to produce cleaner alternative fuels because…
