“…The pour point is the temperature at which a fuel can no longer be poured due to gel formation, while the cold filter plugging point is the temperature at which a fuel jams the filter due to the formation of agglomerates of crystals. 37 Several approaches have been proposed to improve the low temperature properties of biodiesel, including blending with petroleum diesel, the use of additives and the chemical or physical modification of either the oil feedstock or the biodiesel product. Blending with petroleum diesel is only effective at low biodiesel proportions (up to 30 vol.…”

“…Definition and detailed specifications of biodiesel blends are outlined in many foreign countries. The United States allows the use of B6 to B20 blends, and the European Committee for Standardization specifies a maximum of 7 vol% biodiesel mixed into petro‐diesel (Giraldo et al, 2013; Moser, 2012; Sharafutdinov et al, 2012). Indonesia and Argentina have increased the allowable biodiesel blends to B30 (B = biodiesel; 30 = vol% of biodiesel in blends with petro‐diesel) and B20, respectively.…”

Poor cold flow property is a major issue that hinders the application of biodiesel‐diesel blends. In this work, a series of methacrylate‐benzyl methacrylate‐N‐vinyl‐2‐pyrrolidone terpolymers (RMC‐MB‐NVP, R = C12, C14, C16, C18) was synthesized and used as the pour point depressants (PPD) for waste cooking oil biodiesel blends. To further improve their depressive effects, dispersants, including Tween (40, 60, and 80), Span (40, 60, and 80), phthalic acid esters (PAE), and fatty alcohol polyoxyethylene ether (FAPE; FAPE 5, FAPE 7, and FAPE 9), were optimized and combined with the C14MC‐MB‐NVP terpolymers. The effects of C14MC‐MB‐NVP terpolymers and combined PPD (PPDC) on the cloud point (CP), cold filter‐plugging point (CFPP), and pour point (PP) of biodiesel blends were studied. Here, results showed that the presence of dispersants can efficiently enhance the solubility and dispersibility of polymeric PPD in biodiesel blends; thus, the PPDC presents better depressive effects. Among them, C16MC‐MB‐NVP (5:1:1) combined with FAPE 7 dispersant at 4:1 mass ratio (PPDC‐FAPE 7) showed the best synergistic effect, and the CP, CFPP, and PP of B20 treated with 2000 ppm PPDC‐FAPE 7 decreased by 4, 10, and 19 °C, respectively. Moreover, differential scanning calorimetry, polarizing optical microscope, and rheological analyses were performed to rationalize the action mechanism of these PPD and dispersants in biodiesel blends.

“…Atomization of the fuel is that large liquid column or liquid film becomes small droplets. From the perspective of the force, atomization process can be seen as the process of the joint function between the external forces and internal to be torn [4]. Firstly, the air force (external force) on the liquid surface makes liquid column split.…”

Macro-spray structural parameters and micro-droplet of diesel-FAME under the circumstance of different FAME content, injection pressure and nozzle diameter were studied. With the increase of FAME content, the spray penetration increases, and spray angle decreases, molecules viscous force and the micro-droplet size increase, which means the atomization getting worse. With the increases of injection pressure, the penetration increases, the spray angle decreases. The more FAME content, the greater the rate of them. The microscopic droplet size decreases as pressure increasing. With increased nozzle diameter, the cavitations of liquid become weak, the penetration extends, and the spray angle decreases. Droplet size becomes bigger and atomization gets worse.
