Reformed Hydrous-Ethanol Application in Spark Ignition Engine
Hydrous-ethanol is reformed to hydrogen-rich mixture gas which is an excellent fuel for engines. The advantages of this approach are that fossil fuel consumption and CO2 emissions are reduced, and the waste heat from engine exhaust can be used as energy source for hydrous-ethanol evaporating and reforming. The experiment is carried out on a gasoline engine as primary engine with only modest changes. The results indicate that the hydrogen-rich mixture gas allows operation at much higher compression ratio due to its intrinsic octane number which could contribute to the power performance, and the NOx, CO, THC emissions are reduced remarkably because of lean combustion realized in the cylinder.
