“…Table 6 shows that biodiesels derived from soybean, rapeseed, and castor oils have lower cloud and pour points, while tallow methyl ester has higher cloud and pour points. The cloud point of biodiesel depends on the feedstock and its values are in a range of À12 C for castor biodiesel and 16 C for palm biodiesel [48]. Generally, addition of flow improving additives in biodiesel can decrease the size by restraining the formation of wax crystallites when the test fuel is cooled.…”

Biodiesel has emerged as a suitable alternative to mineral diesel in compression ignition (CI) engines in order to ensure global energy security and to reduce engine out emissions in near future. Biodiesel derived from various feedstocks available worldwide fits well in the current fuel supply arrangement for transport sector. However, biodiesel as an alternative transportation fuel has been extensively investigated because of differences in its important fuel properties compared with baseline mineral diesel. Since fuel properties greatly influence spray development, combustion, and emission formation in internal combustion (IC) engines, a number of experimental and computational studies on biodiesel usage in CI engines have been performed to determine its brake thermal efficiency (BTE), gaseous emissions, durability, etc., by various researchers using variety of engines and feedstocks. In the present paper, a critical review of the effect of biodiesel's fuel properties on engine performance, emissions, and combustion characteristics in existing diesel engines vis-a-vis conventional diesel has been undertaken. In addition, the progress and advances of numerical modeling involving biodiesel are also reviewed to determine the effect of fuel properties on spray evolution and development of reaction mechanisms for biodiesel combustion simulations. Fuel properties are discussed in two categories: physical and chemical properties, which are key parameters affecting spray and combustion processes. Subsequent sections review spray, combustion, emissions, and performance characteristics of biodiesels under various engine operation conditions. In the last section of this review paper, numerical modeling of biodiesel covering recent numerical models and schemes to understand the behavior of biodiesel combustion and pollutants formation is included. This review paper comprehensively summarizes biodiesel fuel's (BDFs) spray, combustion, and emission characteristics using experimental and numerical approaches. Limitations and scope for future studies are discussed in each section.

“…Blending of biodiesels with mineral diesel is widely used to resolve the flow problems in cold weather conditions. Mineral diesel component in biodiesel blended fuels acts as a solvent for precipitated crystals, waxes, or gels formed at low temperature [48], thus effectively reducing cold weather related issues.…”

“…Ethanol is a low-cost oxygenate with high oxygen content (approximately 35%) that has been used in biodiesel-ethanol blends [100][101][102][103][104][105]. Ethanol-blended biodiesel is totally a renewable, viable alternative fuel for improved cold flow behavior and better emission characteristics without affecting the engine performance.…”

Summary The use of biodiesel as a diesel fuel alternative is rapidly increasing. An important aspect of applying this alternative is the transportation and application in cold weather. In this article, different kinds of methods and technologies were briefly reviewed to improve the low‐temperature properties of biodiesel. The compositions of fatty acids would be effectively changed by choosing available material with high content of unsaturated fatty acids or by reducing saturated fatty acids via winterization process. Branched alcohols can be used to change biodiesel structures that improve the low‐temperature properties. As a technically feasible method, there is still a constant demand to search cost‐effective raw materials for economic branched alcohols production. In order to enhance the impact of crystal morphology and decrease freezing point, the blending chemical additives and petroleum fuels would be a promising method that have been widely used. Besides, other treatments such as epoxidation, hydroisomerization, and ozonization were also discussed. However, each method applied for improving low‐temperature properties of biodiesel should be effective and economical so that the biodiesel would continue to compete with fossil and other renewable fuels for market share.

Many samples of rapeseed oil ethyl ester were prepared by alkaline-catalyzed transesterification at various conditions (reaction time, temperature, amount of catalyst, the molar ratio of ethanol to oil, the rotations of a disperser and the purification by water). The concentrations of the key impurities for biodiesel quality (the concentrations of monoglycerides, diglycerides, triglycerides, free glycerol, ethanol, free fatty acids, water) and some qualitative parameters (flash point, carbon residue, kinematics viscosity at 40 °C) were determined and then the relationships among them were found out. The relationships were characterized by the linear or non-linear statistical models.The found models enable the better understanding of the significance of the qualitative parameters and estimate them from the concentrations of impurities. The temperature 2 dependence was also measured in the case of the viscosity of ethyl ester and used rapeseed oil.
