“…The innovated fuel blend also increased engine performance parameters, i.e., power and torque by up to 7.81%, 4.91%, respectively, and decreased fuel consumption by 4.50% (Fig. 1) (Mirzajanzadeh et al, 2015). The authors concluded that the unique oxygen donation/absorption properties of CeO2 resulted in CO oxidation reaction.…”

“…Therefore, commercial electrospun polystyrene membranes seem to comparatively hold greater promises for industrial-scale applications given their availability and relatively low cost. (Mohammadi et al, 2014), and combustion improvers (Sadhik Basha and Anand, 2012;Kannan et al, 2011;Mirzajanzadeh et al, 2015) are used in biodiesel to meet specification limits and to enhance quality. In a very recent study, Mirzajanzadeh et al (2015) introduced a novel soluble hybrid nanocatalyst as a promising combustion improver.…”

In a very recent study, Mirzajanzadeh et al (2015) introduced a novel soluble hybrid nanocatalyst as a promising combustion improver. The hybrid nanocatalyst containing cerium oxide on amide-functionalized MWCNT (CeO2-MWCNTs), owing to the high surface area of the soluble nano-sized catalyst particles and their proper distribution along with catalytic oxidation reaction, resulted in significant overall improvements in the combustion reaction specially in B20 containing 90 ppm of the catalyst B20(90 ppm).…”

“…The authors concluded that the unique oxygen donation/absorption properties of CeO2 resulted in CO oxidation reaction. They also stated that CeO2 nano particles owing to their decreasing impact on peak temperature in the combustion chamber led to decreased production of nitrogen oxides (NOx) (Mirzajanzadeh et al, 2015).…”

HIGHLIGHTSThis article fully discusses the recent trends in the production of one the most attractive types of biofuels, i.e., biodiesel.with a focus on the existing obstacles for its large scale production. Moreover, recent innovations/improvements under three categories of upstream, mainstream, and downstream processes are also presented. Upstream strategies are mainly focused on seeking more sustainable oil feedstocks and/or enhancing the quality of waste-oriented ones. The mainstream strategies section highlights the numerous attempts made to enhance agitation efficiency including chemical and/or mechanical strategies. Finally, the innovative downstream strategies basically dealing with 1) separation of biodiesel and glycerin, 2) purification of biodiesel and glycerin, and 3) improving the characteristics of the produced fuel, are comprehensively reviewed.

“…For instance, most of the oxygenated additives show higher brake thermal efficiency in blended biodiesel and decrease the brake specific fuel consumption, as compared to diesel fuel and biodiesel without additives. Moreover, the addition of metallic additives decreases the specific fuel consumption and improves the exhaust gas emissions (Rashedul, et al, 2014); ; (Mirzajanzadeh, et al, 2015). These additives can be obtained from organic and inorganic compounds, and can be modified with metals.…”

A lumina nanoparticles were synthesized by sol-gel method and submitted to thermal treatment at 750 and 1000 °C. X-ray diffraction was used to determine crystal formation with sizes up to 280 nm. To achieve stable suspensions, a nano-additive was mixed with the diesel/biodiesel blends along with oleic acid surfactant to obtain concentrations of nano-additives at 10 and 20 ppm. For this, alumina nanoparticles were firstly mixed with 20 mL of oleic acid by using an ultrasonicator. Then, this mixture was heated at 80°C under constant agitation for 1 hour, and it was subsequently submitted to ultrasound for 30 minutes. Colloidal stability was evaluated according to Deryaguin-Landau-Verwey-Oberbeek (DLVO) theory by analyzing the total interaction energy of the system. Effects on the kinematic viscosity and flash point of the B10 blend were determined according to ASTM D-445 and ASTM D-93 regulations. The application of nano-additives in biodiesel blends showed an increase of the kinematic viscosity from 2.75 cSt to 3.33 cSt at 40°C with 20 ppm of nanoparticles in the B10 blend, while flash point increased from 65 °C to 66 °C. These results could represent a beneficial effect for engines performance due to their better lubricant capacity. On the other hand, fuels with high enough flash point are easy to handle for transportation and storage. Then, the implementation of nano-additives represents a good opportunity for the biofuels industry. ABSTRACTHow to cite: Herrera, Adriana., Ojeda, K.A., Peñaloza, A.D. Rincón, A.

The present study was conducted to investigate the combustion, performance, and emission characteristics of a 10 kW, single cylinder, direct injection diesel engine using cerium oxide nanoparticles (nanocera) added water emulsified Mahua biodiesel blend (NWEB) vis-à-vis water emulsified Mahua biodiesel blend (WEB), B20, and diesel. NWEB was prepared with 69.7 ppm of cerium oxide nanoparticles, 1% surfactants, 10% water, and 2,500 rpm of stirrer. After measuring the fuel properties of test fuels, these were used to run the diesel engine at different engine loads and combustion, performance, and emission parameters were measured. The peak pressure rise rate significantly reduced with NWEB replacing diesel. CA10 and C50 points were observed earlier for NWEB as compared to base fuels. The rapid combustion, controlled combustion, and total combustion duration reduced by more than 5.0, 4.0, and 4.6%, respectively, in engine operation with NWEB over diesel and B20. The maximum brake thermal efficiency of 30.41% was recorded for NWEB as compared to 28.25% for diesel. The mean brake-specific fuel consumption was 3.76 and 3.93% lesser with NWEB as compared to B20 and WEB, respectively. The mean EGT,
