“…The NOx increases with the increase in combustion chamber temperature. The addition of fuel additives to improve fuel properties, thereby the combustion characteristics, have become a recent trend in research due to obvious benefits [16][17][18][19]. It has been reported that nano-additives effectively reduce the agglomeration during blending with fuel and improve engine characteristics due to the large surface air-to-volume ratio, favourable thermophysical properties and high thermal conductivity [20,21].…”

“…It has been reported that nano-additives effectively reduce the agglomeration during blending with fuel and improve engine characteristics due to the large surface air-to-volume ratio, favourable thermophysical properties and high thermal conductivity [20,21]. The combined effect of these properties assists in decreasing BSFC as well as engine emissions [17,19,22]. A previous review by Soudagar et al [1] pointed out an extensive literature gap in the investigations to the addition of various types of nano-additives in various biodiesel feedstocks.…”

The present study examines the effect of silicon dioxide (SiO2) nano-additives on the performance and emission characteristics of a diesel engine fuelled with soybean biodiesel. Soybean biofuel was prepared using the transesterification process. The morphology of nano-additives was studied using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS). The Ultrasonication process was used for the homogeneous blending of nano-additives with biodiesel, while surfactant was used for the stabilisation of nano-additives. The physicochemical properties of pure and blended fuel samples were measured as per ASTM standards. The performance and emissions characteristics of different fuel samples were measured at different loading conditions. It was found that the brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) increased by 3.48–6.39% and 5.81–9.88%, respectively, with the addition of SiO2 nano-additives. The carbon monoxide (CO), hydrocarbon (HC) and smoke emissions for nano-additive added blends were decreased by 1.9–17.5%, 20.56–27.5% and 10.16–23.54% compared to SBME25 fuel blends.

“…Oleic acid has the highest level of fatty acid methyl esters (FAME) in POB (48.5%), followed by palmitic acid (34.7%). Ali et al 22 (oleic acid (49.2%) and palmitic acid (43.3%)), Razzaq et al 23 (oleic acid (45.0%) and palmitic acid (39.9%)), and Kaewbuddee et al 7 (oleic acid (37.07%) and palmitic acid (46.29%)) also observed the same results. In general, the unsaturated fatty acids dominate the POB composition (49.5%).…”

This research was aimed to examine the diesel engine’s performance and emission of secondary fuels (SFs), comprising waste plastic oil (WPO) and palm oil biodiesel (POB), and to analyze their tribological properties. Their compositions were analyzed by gas chromatography–mass spectrometry (GC–MS). Five SFs (10–50% POB in WPO) were prepared by mechanical stirring. The results were compared to blank WPO (WPO100) and Malaysian commercial diesel (B10). WPO90 showed the maximum brake power (BP) and brake torque (BT) among the SFs, and their values were 0.52 and 0.59% higher compared to B10, respectively. The increase in POB ratio (20–50%) showed a negligible difference in BP and BT. WPO70 showed the lowest brake-specific fuel consumption among the SFs. The brake thermal efficiency (BTE) increased with POB composition. The maximum reductions in emission of hydrocarbon (HC, 37.21%) and carbon monoxide (CO, 27.10%) were achieved by WPO50 among the SFs. WPO90 showed the maximum reduction in CO 2 emission (6.78%). Increasing the POB composition reduced the CO emissions and increased the CO 2 emissions. All SFs showed a higher coefficient of friction (COF) than WPO100. WPO50 showed the minimal increase in COF of 2.45%. WPO90 showed the maximum reduction in wear scar diameter (WSD), by 10.34%, compared to B10. Among the secondary contaminated samples, SAE40-WPO90 showed the lowest COF, with 5.98% reduction compared to SAE40-WPO100. However, with increasing POB content in the secondary contaminated samples, the COF increased. The same trend was also observed in their WSD. Overall, WPO90 is the optimal SF with excellent potential for diesel engines.

“…Oxidation stability is significantly increased by the use of antioxidants [162,166,167]. Flash point was reduced when oxygenated, and metalbased additives were used [157,158,160,[168][169][170][171][172] and increased when antioxidants were used [8,166,167]. From Table 4, it can be seen that the cetane number of fuel is significantly increased when antioxidants, oxygenated, metal-based additives, and cetane improvers are used [158,160,162,163,165,[173][174][175].…”

Compression ignition engines play a significant role in the development of a country. They are widely used due to their innate properties such as high efficiency, high power output, and durability. However, they are considered one of the key contributors to transport-related emission and have recently been identified as carcinogenic. Thus, it is important to modify the designs and processes before, during, and after combustion to reduce the emissions to meet the strict emission regulations. The paper discusses the pros and cons of different strategies to reduce emissions of a diesel engine. An overview of various techniques to modify the pre-combustion engine design aspects has been discussed first. After that, fuel modifications techniques during combustion to improve the fuel properties to reduce the engine-out emission is discussed. Finally, post-combustion after-treatment devices are briefly discussed, which help improve the air quality of our environment.
