Key Fuel Properties of Biodiesel-diesel Fuel-ethanol Blends

Utilization of Biodiesel-Diesel-Ethanol Blends in CI Engine

“…As a result, the storage, handling and transportation of biodieseldiesel fuel-ethanol mixtures must be managed in a special and proper way, in order to avoid an explosion. Concerning the cold filter plugging point (CFPP) it was observed that in the case of 5 % ethanol blends it decreases, but it gets higher in the case of 10 % ethanol blends because of the limited ethanol miscibility, which restricts its use at low temperatures (Barabás & Todoruţ, 2009). Surface tension for blends containing 10 % ethanol is comparable to that of diesel fuel.…”

“…For this purpose it is useful to determine the Fuel Energy Equivalence (FEE), which is the ratio of the heating value of the blend and the heating value of diesel fuel. The main properties of the selected blends used (Barabás & Todoruţ, 2009; are shown in Table 2. The densities of the biodiesel-diesel fuel-ethanol blends are in the range of 843.7...851.9 kg/m 3 , very close to the diesel fuel requirement related in EN 590.…”

“…Viscosity at 40 °C was determined using ASTM D7042-04 and for determining surface tension the stalagmometric method was used. The main properties of the biodiesel, diesel fuel and ethanol used (Barabás & Todoruţ, 2009; are shown in Table 1.…”

“…Surface tension for blends containing 10 % ethanol is comparable to that of diesel fuel. Blends with high biodiesel content have a surface tension higher by up to 20 %, due to the higher surface tension of biodiesel (Barabás & Todoruţ, 2009). …”

“…1. Solubility and stability of biodesel-diesel fuel-ethanol blends content, hydrogen content, oxygen content, cetane number and heating value of the blends was evaluated (measured or calculated) (Barabás & Todoruţ, 2009). Density () is a fuel property which has direct effects on the engine performance characteristics (Sandu & Chiru, 2007).…”
