“…The results in Figure 14 show that the fuel D86+B8+E6+G50 has the lowest amount of UHC emissions at all engine speeds. The presence of oxygen in the molecular structure of biodiesel and ethanol and the high catalytic activity of nanopowder improve the chemical process and increase the energy generated in the cylinder, resulting in a more complete combustion of the fuel and a reduction in UHC emissions (Noorollahi et al, 2018;Heidari-Maleni et al, 2021).…”

Today, there are environmental problems all over the world due to the emission of greenhouse gasses caused by the combustion of diesel fuel. The excessive consumption and drastic reduction of fossil fuels have prompted the leaders of various countries, including Iran, to put the use of alternative and clean energy sources on the agenda. In recent years, the use of biofuels and the addition of nanoparticles to diesel fuel have reduced pollutant emissions, improved the environment and enhanced the physicochemical properties of the fuel. The current research deals with the experimental evaluation of emissions and performance of a diesel engine running on graphene nanopowder together with diesel-biodiesel-ethanol blends. The engine variables studied included the engine speed (in three stages: 1800, 2200 and 2600 rpm) and three types of fuel including graphene nanoparticles (with values of 25 and 50 ppm), biodiesel (with volume percentages of 4, 6 and 8) and ethanol (with volume percentages of 2 and 4). The results showed that the power and torque of the D86 + B8 + E6 + G50 fuel increased on average by 20.26% and 28.76% at all engine speeds compared to the D100 fuel. The use of D86 + B8 + E6 + G50 fuel resulted in a significant reduction in CO (38.84%), UHC (21.24%) and NOx (19.92%) emissions compared to D100 fuel. In addition, a significant increase in CO2 emissions (23.19%) was observed. The results of this study clearly show that the use of biofuels and the addition of nanopowder to D100 fuel is a very effective method to improve combustion, performance and emission characteristics in diesel engines.

Modern industrial society is heavily dependent on energy. The amount of energy needed to sustain a society increases as the world's population grows and transportation systems improve. However, the stringent emissions regulations enacted to control the number of harmful exhaust pollutants from heavy-duty diesel engines are likely to gradually phase out internal combustion engines that run solely on petrochemical fuels. This challenge puts constant pressure on researchers to seek improved fuel technologies that meet emission standards while reducing costs and emissions. In this paper, the impact of biodiesel blends, with or without additives was found to have both positive and negative effects on heavy-duty diesel engines. Biodiesel blends with additives such as 50% biodiesel 400mg/l additive and 100 % biodiesel 500mg/l additive have the potential to reduce emissions of harmful pollutants such as particulate matter (PM), carbon monoxide (CO), and hydrocarbons (HC). However, the impact on nitrogen oxide emissions is less clear and may depend on engine type and operating conditions. Regarding engine performance, additive biodiesel blends exhibited lower power and torque output and slightly lower fuel consumption than conventional diesel. On the other hand, non-additive biodiesel blends such as 5%, 10%, and 20% biodiesel in conventional diesel showed higher nitrogen oxide emissions and fuel consumption, but a reduction in HC and CO emissions. Overall, the use of additives in biodiesel blends can improve certain properties, such as cold weather performance and oxidation stability but the effect largely depends on engine design, operating conditions, and the percentage of additives used. Hence, more research is needed to fully understand the effect of biodiesel blends and additives on heavy-duty diesel engines and optimize their use for maximum benefits.
