“…A maximum volume fraction in the flue gas of O 2 and a minimum of CO 2 are observed at the cruise regime (80% RPM), indicating an increase of the air to fuel ratio (AFR). Prior variations are also reported by Chiong et al [13] and Rochelle et al [6,14], in which a higher oxygen content was linked to biodiesel compared to fossil fuel, increasing the percent excess combustion air and thus increasing the AFR. Nonetheless, the evolution of CO and HC presented in Figure 6 exposes a reduction in the volume fraction when increasing the main shaft rotational speed with a minimum value of CO at the take-off regime (100% RPM).…”

“…Several studies of biodiesel blends used in aviation engines have shown no significative detrimental effect on the engine performance compared to the use of pure jet fuels [7,12]. The exhaust gas emissions expose no significant variations of O 2 and CO 2 compounds [13], but a significant rise in CO emissions is reported when increasing the biodiesel content as a result of an inadequate atomizing of the fuel that causes a more incomplete combustion [6,14]. There are still several challenges to overcome with the utilization of biodiesel in aviation turbines regarding the high cost of fuel production, the degradative effect of biofuels over fuel systems linked to the crucial operating safety, and the adjustment of the biodiesel properties to aviation standards [15].…”

Aeronautic transport is a leading energy consumer that strongly contributes to greenhouse gas emissions due to a significant dependency on fossil fuels. Biodiesel, a substitution of conventional fuels, is considered as an alternative fuel for aircrafts and power generation turbine engines. Unfortunately, experimentation has been mostly limited to small scale turbines, and technical challenges remain open regarding operational safety. The current study presents the facility, the instrumentation, and the measured results of experimental tests in a 640 kW full-scale J69-T-25A turbojet engine, operating with blends of Jet A1 and oil palm biodiesel with volume contents from 0% to 10% at different load regimes. Findings are related to the fuel injection system, the engine thrust, and the emissions. The thrust force and the exhaust gas temperature do not expose a significant variation in all the operation regimes with the utilization of up to 10% volume content of biodiesel. A maximum increase of 36% in fuel consumption and 11% in injection pressure are observed at idle operation between B0 and B10. A reduction of the CO and HC emissions is also registered with a maximum variation at the cruise regime (80% Revolutions Per Minute—RPM).

“…Some feedstock types such as non-edible oil plants and waste cooking oil can provide cheaper cost, but these low-cost feedstock types are used to have a higher amount of impurities. Additional treatments are needed in the manufacture to produce standard quality biodiesel with low-cost feedstock to increase man-ufacturing cost such as by using recent technology in machine learning and computational analysis [28][29][30].…”

Biodiesel has caught the attention of many researchers because it has great potential to be a sustainable fossil fuel substitute. Biodiesel has a non-toxic and renewable nature and has been proven to emit less environmentally harmful emissions such as hydrocarbons (HC), and carbon monoxide (CO) as smoke particles during combustion. Problems related to global warming caused by greenhouse gas (GHG) emissions could also be solved by utilizing biodiesel as a daily energy source. However, the expensive cost of biodiesel production, mainly because of the cost of natural feedstock, hinders the potential of biodiesel commercialization. The selection of natural sources of biodiesel should be made with observations from economic, agricultural, and technical perspectives to obtain one feasible biodiesel with superior characteristics. This review paper presents a detailed overview of various natural sources, their physicochemical properties, the performance, emission, and combustion characteristics of biodiesel when used in a diesel engine. The recent progress in studies about natural feedstocks and manufacturing methods used in biodiesel production were evaluated in detail. Finally, the findings of the present work reveal that transesterification is currently the most superior and commonly used biodiesel production method compared to other methods available.
