“…The flash point of vegetable oils is sufficiently high (over 220°C, except for babassu oil ~150°C, while over 66°C for diesel oil) to ensure good handling safety [97], so it is not necessary to measure it. Moreover, the closed cup distillation method, DIN EN 2719, proposed by the pre-standard is not applicable.…”

“…To improve these properties, biodiesel is currently blended with diesel. Moreover, biodiesel fuel blends offer significantly higher lubricity [5] and can be used without modification of the engine [6]. The quality of the fuel-air mixture, which in turn determines the combustion process and emission characteristics, depends on the spray characteristics of the biodiesel-diesel blend [7,8].…”

Abstract:The objective of this study was to investigate the macroscopic spray characteristics of different 0%-100% blends of biodiesel derived from drainage oil and diesel (BD0, BD20, BD50, BD80, BD100), such as spray tip penetration, average tip velocity at penetration, spray angle, average spray angle, spray evolution process, spray area and spray volume under different injection pressures (60, 70, 80, 90, 100 MPa) and ambient pressures (0.1, 0.3, 0.5, 0.7, 0.9 MPa) using a common rail system equipped with a constant volume chamber. The characteristic data was extracted from spray images grabbed by a high speed visualization system. The results showed that the ambient pressure and injection pressure had significant effects on the spray characteristics. As the ambient pressure increased, the spray angle increased, while the spray tip penetration and the peak of average tip velocity decreased. As the injection pressure increased, the spray tip penetration, spray angle, spray area and spray volume increased. The increasing blend ratio of biodiesel brought about a shorter spray tip penetration and a smaller spray angle compared with those of diesel. This is due to the comparatively higher viscosity and surface tension of biodiesel, which enhanced the friction effect between fuel and the injector nozzle surface and inhibited the breakup of the liquid jet.

“…Improvement of BTE can be as a result of better atomisation of the blend, and effects on friction [17]. Atomisation of a fuel is affected by the fuel's surface tension, viscosity and density, jet diameter or Sauter Mean Diameter (SMD), relative velocity of the jets and its surroundings and turbulence [18]. High viscosity of the liquid fuel, leads to poor atomisation and break-up, which increases the SMD and reduces the spray angle.…”

“…High viscosity of the liquid fuel, leads to poor atomisation and break-up, which increases the SMD and reduces the spray angle. The droplets reaching the surface of the cylinder wall can cause dilution of the lubricating oil [18]. This can reduce the friction torque by improving the lubricity around the piston rings during the compression stroke [17].…”

In this study, n-butanol-diesel blends were burned in a turbo-charged, direct injection diesel engine where the brake thermal efficiency, (BTE) or brake specific fuel consumption, (BSFC) was compared with that of ethanol-diesel or methanol-diesel blends in another study by other authors. The test blends used were B5, B10 and B20 (where B5 is 5% n-butanol by volume and 95% diesel fuel-DF). In this study, the BTE was higher and the BSFC improved more than in the other study. Because of improved BTE with increasing brake mean effective pressure, BMEP, the BSFC reduced, however the increased shared volume of n-butanol in DF increased BSFC. Adding n-butanol in DF slightly derated the torque, brake power output with increasing speed, and caused a fall in exhaust gas temperatures, (EGT) which improves the volumetric efficiency and reduces compression work. Therefore, a small-shared volume of n-butanol in DF fired in a turbo-charged diesel engine performs better in terms of BTE and BSFC than that of ethanol or methanol blending in DF.
