“…The peak cylinder pressure at a higher percentage of EGR is marginally lower than B20 at full throttle. The reduction in peak pressure for B20 with EGR may be owing to the de ciency of oxygen available for combustion in the exhaust gas and is admitted to the cylinder, for the control of the NOx and also this may be possible to improve in BTE at part load, and lower combustion temperature inside the cylinder at full throttle (Tamilvanan et al 2021). The cylinder peak pressure for B20 with 5%, 10% and 15% EGR rates is 63.7 bar, 62.3 bar and 61.4 bar, respectively, whereas for diesel and B20 is 68.3 bar, and 67 bar respectively at full throttle.…”

Pollution from diesel engines affects negatively the environment. As a result, there is a worldwide concern about reducing the pollutants emitted by diesel engines. In comparison to diesel fuel, biodiesel combustion produces reduced carbon monoxide (CO2) and unburned hydrocarbon (UHC) emissions, but higher nitrogen oxides (NOx) emissions. The current study is to investigate the thermal and chemical effect of exhaust gas recirculation (EGR) on features of a diesel engine for environmental sustainability. The punnai oil was produced from kernels of punnai seeds and transesterified in two phases using alcohol with the existence of a catalyst. The higher viscosity of punnai oil biodiesel is diluted by mixing it with diesel fuel. Our previous investigation indicated that neat punnai oil biodiesel is a potential fuel; however, the findings showed that the addition of diesel is necessary to obtain acceptable engine performance. In this study, punnai oil biodiesel was mixed at a rate of 20% with diesel (B20) and run in a diesel engine with varied EGR rates under five different engine loads. This combined impact enhanced the maximum heat release rate (HRR) and maximum combustion pressure, according to the findings. The premixed burning fractions were commonly higher at all engine loads, whereas the diffusion combustion fractions were lower. When the centre of the HRR changed toward the top dead centre (TDC), combustion durations remained rather constant. The experimental results revealed B20 blend at 10% EGR flow rate produced 6.57% lower BTE, 37.04% higher BSEC, 2.47% higher EGT, 5.13% lower CO, 31.11% higher CO2, 3.13% higher UHC, 8.36% lower NOx and 4% higher smoke opacity when compared with diesel in a standard diesel engine.

“…The Mass Fraction Burned (MFB) is a normalized parameter with a scale from zero to one or 0-100% for each cycle of the engine, defining the process of emitted chemical energy depending upon the crank angle [99]. The behavior of the MFB for any fuel in an engine is also a basic index of the combustion process [13]. The cetane number, engine load, oxygen content, and the enthalpy of the vaporization are the reasons for the higher influence on the MFB framework [100].…”

“…Because of environmental issues, high cost, and permanent expenditure of petroleum-based non-renewable fuels, the requisition for renewable, and sustainable fuel resources has come into view. In another word, the aforementioned annoyances have quickened the shifting to alternating energy sources that can be employed in place of petroleum-based fuels [12][13][14]. For that reason, some attempts have been made to decline the elevated dependency on fossil-based fuels all over the world in recent years.…”

The core focus of the present investigation is regarding biodiesel production from industrial hemp seed oil applying single-stage homogenous catalyzed transesterification process obtaining high yield of methyl ester. The engine tests were carried out on a single-cylinder, four-stroke, water-cooled, unmodified diesel engine operating with hemp seed oil methyl ester as well as its blends with conventional diesel fuel. The experimental findings of the test fuels were compared with those from diesel. The results pointed out that the performance and combustion behaviors of biodiesel fuels are just about in line with those of diesel fuel propensity. The specific fuel consumption for 5% biodiesel blend (0.291 kg/kW h), 10% biodiesel blend (0.305 kg/kW h), and 20% biodiesel blend (0.312 kg/kW h) blends at full load was closer to diesel (0.275 kg/kW h). In the meantime, the thermal efficiency for biodiesel was found to be at the range of 15.98–24.97% and it was slightly lower than that of diesel (18.10–29.85%) at the working loads. On the other hand, the harmful pollutant characteristics of carbon monoxide, hydrocarbon, and smoke opacity for biodiesel and its blends were observed to be lower in comparison with diesel during the trials. However, the oxides of nitrogen emissions for biodiesel were monitored to be as 6.85–15.40 g/kW h which was remarkably higher than that of diesel (4.71–8.63 g/kW h). Besides that, the combustion behaviors of biodiesel and its blends with diesel showed much the same followed those of diesel. Namely, the duration of ignition delay of biodiesel–diesel blends was shorter than that of diesel fuel because of the higher cetane number specification of the methyl ester. The highest gas pressures inside the cylinder as well as the rates of the heat release of biodiesel including test fuels are lower in contrast to the diesel due to the shorter ignition delay. It could be concluded that the utilization of biodiesel produced from industrial hemp seed oil in the diesel engine up to 20% (by vol.) will decrease the consumption of diesel and environmental pollution, especially in developing countries.

“…These compounds can be efficiently incorporated in biodiesel after proper dissolution in a solvent to enhance the solubility parameters. , Furthermore, the additions of oxygenated additives such as diethyl ether, ethanol, pentanol, decanol, ethylene glycol, propanol, and benzyl alcohol (aromatic alcohol) to biodiesel and biodiesel/diesel blends have been recently explored, and their impacts in engines evaluated. Most of the works showed promising results in terms of performance parameter improvements, like engine efficiency, emissions, and combustion, although the results depend on the amount of additive incorporated in biodiesel or blends. − …”

The control of the oxidative stability of biodiesel and blends of biodiesel with diesel is one of the major concerns of the biofuel industry. The oxidative degradation of biodiesel can be accelerated by several factors, and this is most critical in the so-called second generation biodiesel, which is produced from low-cost raw materials with lower environmental impacts. The addition of antioxidants is imperative to ensure the oxidative stability of biodiesel, and these are considered products of high commercial value. The antioxidants currently available on the market are from synthetic origin, so the existence/availability of alternative antioxidants of natural origin (less dependent on fossil sources) at a competitive price presents itself as a strong business opportunity. This work describes and characterizes a sustainable alternative to synthetic antioxidants used in the biodiesel market developed from extracts of vineyard pruning waste (VPW), which are naturally rich in phenolic compounds with antioxidant properties. A hydrothermal extraction process was applied as a more efficient and sustainable technology than the conventional one with the potential of the extracts as antioxidant additives in biodiesel evaluated in Rancitech equipment. The VPW extract showed comparable antioxidant activity as the commercial antioxidant butylated hydroxytoluene (BHT) typically used in biodiesel. The stability of the biodiesel is dependent from the amount of the extract added. Further, for the first time, the assessment of the environmental impacts of using natural extracts to control the oxidative stability of biodiesel in the production process is also discussed as a key factor of the process environmental sustainability.
