“…The kinematic viscosity of the e-diesel blends for 0 to 90% in volume was measured at 40 o C by Lapuerta et al (26) With regard to the diesel quality norm EN 590, blends with more than 22% (v/v) ethanol would not satisfied the requirement of viscosities above 2 cSt. Those results are in accordance with the previous work (24) . In addition, they had tried to estimate the kinematic viscosity of liquid mixture by introducing the correlation suggested by Grunberg-Nissan (27) , but failed to obtain the reasonable result.…”

“…Only two studies in the literature were found in relation to surfacte tension of e-diesel. The exponential decrease of the surface tension from E0 to E25 in e-diesel was found by Li et al (24) The surface tension of e-diesel exponentially decreased with increase in bioethanol content up to 20% of bioethanol, and thereafter addition of bioethanol didn't affect the surface tension of e-diesel (29) . It should be pointed out that the exact value of surface tension for the same e-diesel was widely different from two studies, due to different surface tension of diesel tested in the experiment, respectively.…”

“…Viscosity: The kinematic viscosity of five ethanoldiesel blended fuels (E5, E10, E15, E20 and E25) as well as petro-diesel (E0) was reported by Li et al (24) They found that the addition of ethanol to diesel lowers the viscosity of blended fuel. However, up to ethanol content of 20%, the kinematic viscosity of ediesel fulfill the minimum requirements for diesel fuel.…”

This review will be concentrated on the spray characteristics of bioethanol and its derived fuels such as ethanol-diesel, ethanol-biodiesel in compression ignition (CI) engines. The difficulty in meeting the severe limitations on NOx and PM emissions in CI engines has brought about many methods for the application of ethanol because ethanol diffusion flames in engine produce virtually no soot. The most popular method for the application of ethanol as a fuel in CI engines is the blending of ethanol with diesel. The physical properties of ethanol and its derivatives related to spray characteristics such as viscosity, density and surface tension are discussed. Viscosity and density of e-diesel and e-biodiesel generally are decreased with increase in ethanol content and temperature. More than 22% and 30% of ethanol addition would not satisfied the requirement of viscosity and density in EN 590, respectively. Investigation of neat ethanol sprays in CI engines was conducted by very few researchers. The effect of ambient temperature on liquid phase penetration is a controversial topic due to the opposite result between two studies. More researches are required for the spray characteristics of neat ethanol in CI engines. The ethanol blended fuels in CI engines can be classified into ethanol-diesel blend (e-diesel) and ethanol-biodiesel (e-biodiesel) blend. Even though dodecanol and n-butanol are rarely used, the addition of biodiesel as blend stabilizer is the prevailing method because it has the advantage of increasing the biofuel concentration in diesel fuel. Spray penetration and SMD of e-diesel and e-biodiesel decrease with increase in ethanol concentration, and in ambient pressure. However, spray angle is increased with increase in the ethanol percentage in e-diesel. As the ambient pressure increases, liquid phase penetration was decreased, but spray angle was increased in e-diesel. The increase in ambient temperature showed the slight effect on liquid phase penetration, but spray angle was decreased. A numerical study of micro-explosion concluded that the optimum composition of e-diesel binary mixture for micro-explosion was approximately E50D50, while that of e-biodiesel binary mixture was E30B70 due to the lower volatility of biodiesel. Adding less volatile biodiesel into the ternary mixture of ethanol-biodiesel-diesel can remarkably enhance micro-explosion. Addition of ethanol up to 20% in e-biodiesel showed no effect on spray penetration. However, increase of nozzle orifice diameter results in increase of spray penetration. The more study on liquid phase penetration and SMD in e-diesel and e-biodiesel is required.

“…The use of ethanol, besides reducing dependence on fossil fuel, would help to reduce emissions of greenhouse gases in the cycle diesel engine (RAHIMI, 2009 The addition of ethanol in diesel oil causes in the latter physical and chemical changes, noticeable reduction in cetane number, viscosity, and flash point (LI et al, 2005). These modifications change the characteristics of the fuel jet injected into the cylinder, the quality of combustion, and emissions of pollutants from the engine.…”

Abstract.Th e article provides a closer look into the quality properties of fuels, analyses the merits and demerits of using biocomponents in petrol and diesel and overviews the ways of improving the quality of fuels. Work carried out by the authors covers the determination of the basic quality properties (density, kinematic viscosity and fl ash point) of petrol, diesel, methanol, ethanol, buthanol as well as rape methyl and rape ethyl esters. Th e paper investigates how these qualities infl uence the operational performance of the engine and puts forward the age-dependence analysis of diesel quality properties.
