文摘
- •
Effects of 0–50% n-butanol addition on GDI engine are experimentally studied.
- •
Higher n-butanol fractions increase combustion pressure and fasten burning rate.
- •
Higher n-butanol fractions increase BSFC but improve BTE.
- •
Higher n-butanol fractions enhance combustion stability but increase knock intensity.
- •
Higher n-butanol fractions reduce exhaust temperature and NOx emissions.
