“…The lower HC emission ensures that the combustion is perfect with the fuel's good atomization [71,72]. Redfern et al [73] performed a 60,000 km durability test on a EURO II and a EURO IV diesel engine using B10 and B8 blends. They found that total polycyclic in the EURO II engine aromatic hydrocarbons emissions was less when biodiesel was used.…”

As non-renewable conventional fossil fuel sources are depleting day by day, researchers are continually finding new ways of producing and utilizing alternative, renewable, and reliable fuels. Due to conventional technologies, the environment has been degraded seriously, which profoundly impacts life on earth. To reduce the emissions caused by running the compression ignition engines, waste cooking oil (WCO) biodiesel is one of the best alternative fuels locally available in all parts of the world. Different study results are reviewed with a clear focus on combustion, performance, and emission characteristics, and the impact on engine durability. Moreover, the environmental and economic impacts are also reviewed in this study. When determining the combustion characteristics of WCO biodiesel, the cylinder peak pressure value increases and the heat release rate and ignition delay period decreases. In performance characteristics, brake-specific fuel consumption increases while brake-specific energy consumption, brake power, and torque decrease. WCO biodiesel cuts down the emissions value by 85% due to decreased hydrocarbon, SO2, CO, and smoke emissions in the exhaust that will effectively save the environment. However, CO2 and NOx generally increase when compared to diesel. The overall economic impact of production on the utilization of this resource is also elaborated. The results show that the use of WCO biodiesel is technically, economically, environmentally, and tribologically appropriate for any diesel engine.

“…Increased consumption of liquid fossil fuels and rising fuel prices with constant demands to reduce environmental pollution from the exhaust gases of internal combustion engines are leading to an intensified search for alternative solutions, especially to replace diesel fuel, which plays a significant role as fuel for diesel engines in transport vehicles and in a wide range of mobile machinery used in construction, agriculture and many other industrial activities. Diesel engines were reported as one major mobile emission sources of pollutants, including carbon monoxide (CO), total hydrocarbons (HC), nitrogen oxides (NOx), and particulate matter (PM) [1]. Together with the development of high conversion efficiency diesel engines, cost-effective after treatment technologies and advanced clean combustion concepts, using cleaner alternative fuels is one of the focuses of pollutant reduction techniques [2].…”

A significant amount of waste cooking oil (WCO) remains in the food preparation process worldwide on a daily basis, which can cause environmental pollution if disposed of improperly. The cheapest and effective way to dispose of WCO is by blending it with diesel fuel. In this study three various blends of WCO and diesel fuel were prepared with a WCO proportion of 10%, 20% and 30% and properties were evaluated and compared with petroleum diesel fuel. The density and dynamic viscosity of the blend increase with the increase in WCO content, while the heating value decreases. The blends were then tested in tractor direct injection diesel engine to determine the effect of blending WCO with diesel fuel on the engine performances (power, torque and fuel consumption) and exhaust gases emission (CO, CO 2 , HC and NO x ). The results show that the engine performances using WCO blends are comparable to petroleum diesel fuel and a blend with 30% WCO (B30) achieved the best results among the fuel blends. There were no significant differences in average engine power, torque and fuel consumption per hour between petroleum diesel fuel and B30 blend, while significantly lower (P˂0.05) average specific fuel consumption were achieved using diesel fuel. The significantly lower (P˂0.05) average CO and CO 2 emissions and significantly higher (P˂0.05) average HC emission was achieved using diesel fuel compared to B30 blend. No significant difference in average NO x emission was observed between diesel fuel and B30 blend.

“…Many researchers are concerned by mobile source air pollution, which causes environmental problems and is associated with adverse health effects. Compared with gasoline engines, diesel engines yield more emissions of pollutants, including soot, black smoke, nitrogen oxides, trace metals (Liati et al, 2015) and harmful components (e.g., polycyclic aromatic hydrocarbons (PAHs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs)) (Cheruiyot et al, 2016;Redfern et al, 2017;Tsai et al, 2018). Diesel PM has a diameter smaller than 1 µm, and thus can be easily inhaled into the respiratory system (Baldauf et al, 2016;Gao and Tian, 2019).…”

“…Biodiesel is recognized to be one of the ways to successfully reduce diesel engine pollutant emissions (Wang et al, 2016;Lin et al, 2017;Redfern et al, 2017). Biodiesel is environmentally friendly, but has slightly higher fuel consumption (Mwangi et al, 2015;Lin et al, 2017) and levels of trace metals on the particles in the exhausts than standard diesel fuel under the same operating conditions (Shukla et al, 2017).…”

To elucidate the characteristics of fine particulate matter pollutant emitted from a diesel engine, a fossil-based diesel fuel (D100) and two blended fuels consisting of D100 and waste cooking oil (WCO) convered biodiesel (W) are tested with a diesel engine generator at loads of 1.5 kW and 3.0 kW. The blended fuels contain 20% and 40% W and are referred to as W20 and W40, respectively. The PM 2.5 emissions and their polycyclic aromatic hydrocarbon (PAH) and metallic components are investigated. Experimental results show that higher concentrations of PM 2.5 , PM 2.5 -bound ΣPAHs and Σmetals, and ΣBaP eq are generated at the 3.0 kW load, with its greater fuel consumption (FC), than the 1.5 kW load. Additionally, of the three fuels, using W20 emits the lowest concentrations of PM 2.5 , PM 2.5 -bound ΣPAHs, and ΣBaP eq . Specifically, the reduction in ΣBaP eq mainly results from the effective inhibition of HMW-BaP eq . Conversely, when using W40, the PM 2.5 -bound Σmetals significantly decreases, and its composition is strongly affected by the metallic content in the fuel. Although W20 and W40 exhibit higher FC (3.0% more) and brake-specific fuel consumption (BSFC; 3.1% more) than D100, they generate lower concentrations of PM 2.5 (18.1% less), PM 2.5 -bound ΣPAHs (22.8% less) and Σmetals (22.0% less), and ΣBaP eq (35.0% less) at both engine loads. The emission factors of these pollutants in the engine exhaust are also reduced, particularly at the higher load (3.0 kW). Accordingly, WCO-based biodiesel additives may decrease the PM 2.5 , PAHs, and metals exhausted by diesel engines, thus reducing the BaP eq of these emissions.
