- •
Ethanol fuel used was obtained by renewable energy source of grape pomace.
- •
High ethanol blends improve performances IMEP COV and flame speed reduce UHC and soot emission.
- •
Flash-boiling strongly affects charge formation and structural behavior of sprays.
- •
E50 experiences fastest vaporization due to its peculiar evaporating properties.
- •
E85 spray shows a more defined boundary indicating the slowest vaporization.
