Este trabalho apresenta uma avaliação experimental da influência de diferentes propriedades da gasolina na eficiência energética e no desempenho de motores GDI Turbo e veículos flex-fuel da fase L7 do Proconve. Na seleção das formulações candidatas, foram aplicadas metodologias expeditas para avaliação de parâmetros de desempenho de gasolinas em testes de bancada, como medições avançadas de atraso de ignição, velocidade de queima e parâmetros de desempenho, com motor monocilíndrico instrumentado. A partir de uma matriz de 17 formulações experimentais, foram selecionadas 6 para ensaios de desempenho e eficiência em motores GDI Turbo e de eficiência energética em um veículo GDI Turbo L7. Os resultados permitiram identificar formulações de gasolina com maiores ganhos de eficiência energética do que outras com níveis superiores de octanagem. Tais resultados podem ser úteis nas discussões quanto às especificações futuras, bem como abrem a perspectiva de novas pesquisas aplicadas para formulação de gasolina.

This paper presents an experimental evaluation of the influence of different gasoline properties on the energy efficiency and performance of GDI Turbo engines and flex-fuel vehicles of the L7 phase of Proconve. In the screening of candidate formulations, expeditious methodologies were applied to evaluate gasoline performance parameters in bench tests, such as advanced measurements of ignition delay, burning speed, and performance parameters, with a single-cylinder instrumented engine. From a matrix of 17 experimental formulations, 6 were selected for performance and efficiency tests on GDI Turbo engines and energy efficiency on a GDI Turbo L7 vehicle. The results allowed the identification of gasoline formulations with greater energy efficiency gains than others with higher octane rating levels. Such results may be useful in discussions regarding future specifications, as well as open the prospect of new research applied to gasoline formulation.
