Performance and exhaust emissions of a CI engine using Bi2O3 nano blends as an alternate Caulerpa racemosa algae oil biofuel

Recent advancement in the application of metal based nanoadditive in diesel/biodiesel fueled compression ignition engine: A comprehensive review on nanofluid preparation and stability, fuel property, combustion, performance, and emission characteristics

“…Addition of Ag 2 O NP to neat neem oil biodiesel at doping levels of 5 and 10 ppm increased BTE by 12.94% and 7.06%, respectively 92 . 50–100 ppm Bi 2 O 3 NP doped B20 blend of algae biodiesel improved BTE compared to algae biodiesel blend without additive 93 . BTE of a water cooled, direct injection, Kirloskar TV1, CI engine was increased by 5% at full load for B10 blend of diesel‐Cinnamon oil biodiesel blend mixed with 30 ppm CeO 2 compared to fossil diesel 192 .…”

“…Most literatures revealed that inclusion of NPs with neat biodiesel and biodiesel blend led to increased HV of the fuels. For example, addition of Fe, Al 2 O 3 , Ag 2 O, Bi 2 O 3 , CeO 2 , CuO, Cr 2 O 3 , Fe 2 O 3 , RuO 2 , ZnO, Ce‐ZnO NPs to diesel‐biodiesel blend resulted in increased HV of the fuel blend 41,57,64,79,92–94,100,104,110,112 . In addition, inclusion of Al 2 O 3 , Ag 2 O, CeO 2 , FeCl 3 , Fe 2 O 3 NPs with neat biodiesel led to increased HV of the fuel 87,92,95,101,102 .…”

“…Inclusion of 5 and 10 ppm Ag 2 O NP increased KV of neat neem oil methyl ester (NOME) by 0.93% and 1.64% respectively 92 . Doping of 50, 75, and 100 ppm Bi 2 O 3 NPs with B20 blend of algae biodiesel also increased KV of the fuel blend by 26%, 19.87%, and 19.45% respectively 93 . Addition of 100 ppm CeO 2 NP with B20 and B50 blends of MME decreased KV of the blends by 0.5 and 0.4 mm 2 /s respectively, 94 Similarly, addition of CeO 2 NP to neat CIME at dosage levels of 20, 40, and 60 ppm 95 and LGO‐water emulsion (O93W5) at a concentration level of 30 ppm 36 helped reduce KV of the fuels.…”

“…However, inclusion of 250 ppm ZnO NP with diesel‐POME‐ethanol blend (D40B30E30) led to decreased CN of the fuel by 3.66% 111 . In addition, Bi 2 O 3 NP at dosage levels of 50 and 100 ppm reduced CN of diesel‐algae biodiesel blend (B20) by 5.56% and 1.85%, respectively 93 …”

An Experimental Assessment of Combustion, Emissions, and Performance Behavior of Diesel Engine Fuelled With New Developed Biofuel Blend of Two Distinct Waste Cooking Oils and Metallic Nano-particle (Al2O3)

“…The researcher observed that B20 demonstrates higher BSFC than diesel at various load conditions; it might be because of the lower calorific value of the fuel. the same power generation on the shaft of the engine [31]. It is additionally seen that the addition of CeO 2 and MgO nanoparticles in WCO biodiesel fuel lessens specific fuel consumption when it is contrasted and that of unadulterated diesel, inferable from the decrease in ignition delay and expanded surface-to-volume proportion which gives better ignition and less utilization of fuel [32].…”
