Blends of 75% gasoline and 25% ethanol (E25) are unique fuels used in Brazil. The natural E25 oxidation process due to aging under atmospheric conditions has been investigated. To evaluate aging effects on the properties of commercially available fuel blends, two samples of regular E25, one sample of regular E25 with additives, and one sample of high octane E25 were tested. The samples were analyzed...
The impact of different fuels, gasoline, two ethanol–gasoline blends (E5, E85) and compressed natural gas (CNG), as well as lubricating oils on the aging behavior of Three-Way-Catalysts (TWCs) has been investigated with six state-of-the-art passenger cars over 40,000km under real world driving conditions. For the study, all vehicles have been equipped with identical TWCs. During the investigation...
