“…The high thermal conductivity of graphene improves fuel properties, combustion, and engine performance. There is very little information available about graphene nanoparticles as a biodiesel additive [9]. Cooler combustion, cleaner lubricating oil, lower octane requirements, and lower emissions are all advantages of having a clean combustion chamber.…”

The exploitation of fossil fuels has fueled the modern world’s development since the industrial revolution. Other energy sources, such as wood, charcoal, and animal power, were displaced by these fuels, which were relatively easy to obtain, had low cost of production, and were easily transportable. The possibility of these fossil reserves being depleted in the medium term, combined with an increase in environmental awareness and the reality of environmental degradation, has changed the situation, reactivating the search for alternative fuels. Biofuels such as bioethanol, biomethanol, and biodiesel are among the alternative fuels gaining popularity due to their environmental benefits. This research investigates the behaviour of a diesel engine that runs on biodiesel (a fuel made from new and unrefined algae oil), ethanol (an essential raw nanomaterial that is readily available in India), and nanometal additives.

“…From the result B25 have the maximum reduction rate in BSFC and B10 have the minimum reduction rate in BSFC. Previous study has shown the higher percentage of biodiesel have higher reduction rate of BSFC when CeO 2 nano additives are mixed with biodiesel 38 , 39 . Moreover, the fuel consumption reduced as the biodiesel ratio increased in the blends as shown in Fig.…”

The implications of adding cerium oxide (CeO2) nanoparticles as a fuel additive to a castor oil biodiesel–diesel fuel blend on engine performance and emissions in a single-cylinder four-stroke diesel engine under various speed were examined in the current study. The test fuels used were fossil diesel fuels, B5 blend biodiesel (as 5% biodiesel and 95% diesel), B10 blend biodiesel (as 10% biodiesel and 90% diesel), B15 blend biodiesel (as 15% biodiesel and 85% diesel), B20 blend biodiesel (as 20% biodiesel and 80% diesel), and B25 blend biodiesel (as 25% biodiesel and 75% diesel), with cerium oxide (CeO2) nanoparticle additive (75 ppm). The result of the physio-chemical properties of the oil samples was within the limit of the ASTM standard. The addition of CeO2 nano additive to the biodiesel–diesel blends has demonstrated a significant reduction in emission and increased in engine performance for all biodiesel–diesel blends for the engine operating speed range. From the result B25 have the maximum reduction rate in BSFC and B10 have the minimum reduction rate in BSFC. The average maximum increment of thermal efficiency was 22.2% for B10 with CeO2 inclusion. CO emission increased as engine speed increased. HC emission was reduced for all blend, with and without CeO2 nano additions as speed increased. Maximum NOx emission was seen at the rated speed of 2700 rpm without nano additive and at 2900 rpm with nano additive. CeO2 nano additive reduced the soot opacity by 11.56% for all biodiesel–diesel blends for the engine operating speed range. As the objective of this study the results indicates CeO2 nano additive reduced emissions and improved the performance. So, using sustainable biodiesel–diesel blends made from castor oil with CeO2 nano additive advisable in ideal operating conditions for diesel engines.

“…When the FIT is advanced, even though the temperature of air is lesser, due to the addition of nanoparticles, whose thermal conductivity is greater than the base fluid, causes enhanced energy transfer between air and fuel particles. (Kalaimurugan et al, 2020) This allows quickly the mixture to reach the auto ignition temperature or in other words the ignition delay will be reduced. Hence more uniform combustion will be achieved, and hence higher heat release takes place, whereas, BTE during retarding FIT, is lower than the earlier.…”

Waste cooking oil (WCO) biodiesel is becoming promising fuel for compression ignition (CI) engines. Due to the poor thermal efficiency, engine modifications and fuel modifications have been adopted over the years to enhance the performance. In the current study, performance from the biodiesel engine at different injection timing has been studied using waste cooking oil biodiesel mixed with cerium oxide (CeO 2 ) nanoparticles as additives. Experiments are conducted at normal injection timing (27 °bTDC), advanced (30 °bTDC) and retarded injection timing (24 °bTDC) using B20 fuel blended with 80 ppm of nanoparticles. Studies indicated that advancing the injection timing, results in higher brake thermal efficiency (BTE) and reduced brake specific fuel consumption (BSFC) for B20 fuel with nanoparticles as compared to fuel without the use of nanoparticles. Smoke, CO and HC emissions reduced on progressing the injection timings, whereas delaying injection timing shows decreased NOx emissions. By advancing the injection timing and adding CeO 2 nanoparticles to the blend, BTE is increased by 10.9% and BSFC reduced by 11.1% as compared to the neat B20 biodiesel operation. HC and smoke emissions are 35.4% and 14.2%, respectively, reduced for advancing the injection timing with the adding cerium oxide nano particles to the fuel as compared with clean WCO ester with the absence of nanoparticles. Advancing fuel injection timing has no positive influence on the reduction of NOx.
