在目前的工作中，巴西C型汽油样品预先与浓度为20、40、60和80体积%的水合乙醇混合，通过蒸馏、辛烷值、比重、pH值和电导率分析，以评估物理化学性质，从而更好地理解弹性燃料技术所造成的影响。将获得的结果与巴西国家石油天然气和生物燃料管理局的规范进行了比较，该机构是巴西燃料质量监测的联邦监管机构。据观察，存在一个理想的浓度的水合乙醇添加到汽油类型C，以获得良好的性能，在灵活燃料技术的应用。
In the present work, samples of Brazilian gasoline type C previously mixed with hydrated ethanol at concentrations of 20, 40, 60 and 80 vol.% were analyzed by distillation, octane number, specific mass, pH and conductivity, in order to evaluate the physico-chemical properties for a better comprehension of the effects caused by the flex-fuel technology. The obtained results were compared with the specifications of the ANP – Agência Nacional de Petróleo Gás Natural e Biocombustíveis – that is the federal regulatory agency for monitoring of the quality of fuels in Brazil. It was observed that there exists an ideal concentration of hydrated ethanol for addition in gasoline type C in order to obtain good properties for application in the flex-fuel technology.
