“…Many researchers have conducted plenty of valuable research using water in base fuel (for both diesel and biodiesels) by many researchers and depicted interesting results. The experimental results of Vellaiyan et al show that 10% water in diesel fuel reduces the NOx, HC, CO, and smoke emissions by 32.5%, 9.9%, 12.8%, and 17.8%, respectively, at peak engine load conditions [4]. The same authors reported in another study that 10% water in diesel fuel improves the BSFC and BTE by 6.6% and 12%, respectively.…”

“…While considering LPOW emulsion fuels, the HC emission further gets diminished for 10WLPO on a par with ND and LPO. This may be a consequence of secondary atomization that leads to complete combustion [4]. An improvement in HC emission for 10WLPO compared to pure LPO is 18.6% at peak load conditions.…”

“…Plenty of valuable studies have been conducted by many researchers in the domain of rst-second-and third-generation biodiesels. The main sources for rstgeneration biodiesel are edible oils such as palm, soybean, corn, and rapeseed oils [4,5]. Though these oils are renewable and environmentally friendly, oil production competes with food crops that lead to food-energy con ict.…”

“…To improve the cetane number of the fuel, nano additives and other chemical agents are recommended by many researchers. Though the presence of the nanoparticles signi cantly improves the engine characteristics, the nanoparticle emissions to the atmosphere and the fuel cost are identi ed as major concerns [4,19]. The cetane improver is a suitable option to improve the fuel properties.…”

Waste-to-energy and its utilization in the commercial field have received wider attention in recent years. Lemon peel oil (LPO), a food waste by-product is used for this study to produce bioenergy, and a novel approach has been attempted to improve energy and environmental efficiency. The LPO was blended different percentages of water and 2-Ethylhexyl nitrate (EHN) and the energy, environmental and economic assessments were carried out. The outcomes show that LPO dominates the normal diesel in all aspects, except for NOx emission, and 10% of water in LPO (10WLPO) improves the overall performance. Meanwhile, this trend is reversed for 20% water in LPO (20WLPO) due to longer ignition delay period and low cetane numbers. EHN plays a vital role in fuel modification and EHN blended 20WLPO significantly improves the engine characteristics, and the engine behaviour is identical to 10WLPO. The cost-benefit analysis shows that 10WLPO fuel significantly reduces the running cost by 4.5% compared to neat diesel, and the cost is further reduced to 9.2% while the LPO is blended with 10% water.

“…21 Additionally the higher latent heat absorption of water molecules further reduce the peak flame temperature to reduce the NOx emissions. 8,10 Therefore, most of the researchers have reported the decrease in NOx emissions for all emulsified diesels at all the operating conditions. 10,22 For the current study, Figure 4 shows that NOx emissions are increasing as the load is increased but they decrease when water percentage in the diesel is increased.…”

Use of diesel and emulsified diesel in CI engine: A comparative analysis of engine characteristics

et al. 2021

Despite a number of efforts to evaluate the utility of water-diesel emulsions (WED) in CI engine to improve its performance and reduce its emissions in search of alternative fuels to combat the higher prices and depleting resources of fossil fuels, no consistent results are available. Additionally, the noise emissions in the case of WED are not thoroughly discussed which motivated this research to analyze the performance and emission characteristics of WED. Brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) were calculated at 1600 rpm within 15%–75% of the load range. Similarly, the contents of NOx, CO, and HC, and level of noise and smoke were measured varying the percentage of water from 2% to 10% gradually for all values of loads. BTE in the case of water emulsified diesel was decreased gradually as the percentage of water increased accompanied by a gradual increase in BSFC. Thus, WED10 showed a maximum 13.08% lower value of BTE while BSFC was increased by 32.28%. However, NOx emissions (21.8%) and smoke (48%) were also reduced significantly in the case of WED10 along with an increase in the emissions of HC and CO and noise. The comparative analysis showed that the emulsified diesel can significantly reduce the emission of NOx and smoke, but it has a negative impact on the performance characteristics and HC, CO, and noise emissions which can be mitigated by trying more fuels variations such as biodiesel and using different water injection methods to decrease dependency on fossil fuels and improve the environmental impacts of CI engines.

Water‐in‐diesel emulsions (WiDEs) have been developed in recent times to assuage costs as well as to minimize lethal emissions from diesel combustion, without engine modification. This study investigated the stability behavior of WiDE and the corrosion inhibition efficacy of the ethanol extract of Ocimum gratissimum (O. gratissimum) toward mild steel. The corrosion susceptibility of mild steel coupons immersed in the different WiDE formulations was monitored using gravimetric and surface probe techniques. The anti‐corrosion effect of O. gratissimum was also assessed. The findings revealed that out of WiDE with three different water content, WiDE with 10% water content had optimal stability and emulsion stability declined with a rise in water content. The mild steel's corrosion rate decreased with a rise in exposure duration. The ethanol extract of O. gratissimum has a substantial impact on the corrosion behavior of mild steel in WiDE, reaching an inhibition efficiency of 91.58%. Also, the apparent surface roughness and roughness data (Sq, Sa,) of mild steel immersed in WiDE10 are higher than the WiDE10 inhibited with O. gratissimum extract, which shows that corrosion was reduced upon the addition of O. gratissimum extract. The FTIR spectra proved the adsorption of the extract constituents on the mild steel surface in WiDE.
