摘要: Abstract The aim of this study was to estimate mathematical relationships between higher heating value (HHV) and viscosity, density or flash point measurements various biodiesel fuels. HHV is an important property defining the energy content thereby efficiency fuels, such as vegetable oils biodiesels. biodiesels were characterized for their physical main fuel properties including density, value. viscosities (2.8–5.1 mm 2 /s cSt at 311 K) much less than those pure (23–53 mm 311 K), HHVs approximately 41 MJ/kg 10% petrodiesel fules (∼46 MJ/kg). Compared No. diesel fuel, all oil methyl esters slightly viscous. values are highly lower oils. measured correlated using linear least square regression analysis. There high viscosity samples. An increase in from 848 885 g/L increases 2.8 5.1 cSt regular. esters. considerably
