“…The CO and HC emissions are caused by incomplete combustion. Emulsified diesel reduces the in-cylinder temperature hence lower combustion efficiency "higher percentage of heat losses" hence high CO emission compared to base fuel [16,38,57,[59][60][61][62]. Interestingly, the emulsion fuel does not have a major effect on HC emission compared to base fuel and that is obtained from micro-explosion resulting from better atomization of emulsified fuel [16,38].…”

The diesel engine’s superior energy conversion efficiency and cost-effective power source have made it a popular choice for a wide range of applications, including but not limited to agricultural machinery, transportation, and mining equipment. Diesel engines produce harmful emissions, including exhaust fumes that contain pollutants such as particulate matter and nitrogen oxides. These emissions are detrimental to the environment and public health, and as a result, strict standards are imposed to reduce them using modern technologies in diesel engine manufacturing, exhaust treatment systems improvement and fuel modifying technologies. This chapter reviewed the effect of wide verity of fuel in diesel engine performance and emission.

“…The updated design consists of static mixers and booster pumps to facilitate fluid turbulence and promote mixing. This design concept was tested by Mahdi et al 26 and it was found that when 7–10 vol% of water content in W/D emulsion were mixed at 3500 rpm for 1 min, stability was maintained within 128 s. In the same study, pilot tests on a mechanical injection-type diesel engine showed lower NO x and fuel consumption, implying that W/D emulsions produced using this design exhibit similar qualities to the original RTES design.…”

Malaysia is one of the top exporters of palm oil, and although currently facing fierce resistance towards palm oil imports in some parts of the globe, one of the ways to utilize this commodity is by increasing palm biodiesel content in local commercial diesel. However, due to the oxygen-rich nature of biodiesel, its utilization suffers from increased nitrogen oxides (NOx) emission compared to conventional diesel. To mitigate this issue and improve diesel engine performance and emissions using biodiesel–diesel blends, this study attempted to investigate implementation of a real-time non-surfactant emulsion fuel supply system (RTES) which produces water-in-diesel emulsion as fuel without surfactants. NOx reducing capability of water-in-diesel produced by RTES has been well documented. Therefore, in this study, 30% biodiesel–diesel (B30) was used as the base fuel while B30-derived emulsions consisting of 10 wt%, 15 wt% and 20 wt% water content were supplied into a 100 kVA, 5.9-L common rail turbocharged diesel engine electric generator. Fuel consumption and exhaust emissions were measured and compared with commercially available Malaysian low grade diesel fuel (D2M). Evidence suggested that emulsified B30 biodiesel–diesel produced by RTES was able to increase brake thermal efficiency (BTE) up to a maximum of 36% and reduce brake specific fuel consumption (BSFC) up to 8.70%. Furthermore, B30 biodiesel–diesel emulsions produced significantly less NOx, carbon monoxide and smoke at high engine load. In conclusion, B30 biodiesel–diesel emulsions can be readily utilized in current diesel engines without compromising on performance and emissions.

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.
