摘要: To investigate the effects of different alcohol additives in biodiesel fuel on spray, combustion characteristics, and soot formation oxidation, a detailed comparative study between butanol−biodiesel blend ethanol−biodiesel was carried out an optical constant volume chamber. Two volumetric fuels were tested this with ambient temperatures at start injection (from 800 to 1200 K). The ratios 20% butanol/80% soybean referred as B20S80 ethanol/80% E20S80. Results demonstrated that microexplosion occurred for E20S80 900 K temperature because volatility difference (butanol or ethanol) base (biodiesel). presented higher peak pressure shorter duration compared fuel. autoignition earlier 1000 ambi...
