This work reviews the numerous key parameters of each alcohol and their effect on CI engine characteristics. The second part of the review emphasizes the effect of nanoadditive addition on diesel and biodiesel owing to their physical and chemical features. A more detailed evaluation of the influence of nanoadditives on diesel engine behavior was done when diesel and biodiesel were doped at varying doses. According to the review, alcohols with a greater carbon concentration, such as butanol and pentanol, have superior miscibility and stability versus alcohols with lesser carbon elements. Additionally, the lower cooling impact and autoignition capability generated by high-alcohol concentrations would make this the optimum additive formulation for usage with diesel fuel. Nanoparticles have been added to fuels used in diesel engines to improve performance and reduce emissions in recent years. The utilization and preparation of fossil-based fuels increase environmental-related issues. Different nanomaterials assorted with fuels for compression ignition (CI) engines and their effects are reviewed in this work. Nanomaterials added to pure diesel and blends of diesel and biodiesel are considered for the study. The physiochemical properties of different fuels with nanoadditives are summarized. Performance characteristics such as brake-specific fuel consumption (BSFC), brake thermal efficiency (BTE), and exhaust gas temperature (EGT) are analyzed and compared for various fuel and nanoadditives combinations. Combustion characteristics and mass fraction burned are investigated. The values of various emissions from the engines fuelled with different combinations are examined. Among the various fuels and nanoadditives studied, 100 ppm TiO2 added diesel consumes the lowest BSFC of 0.3 kg/kWh. Hurdles faced in the current utilization of nanoadditives in diesel engines and the scope for future research are also highlighted.

The world is presently confronted with the twin crisis of resource restriction and environmental degradation. The search for solutions that promise a harmonious correlation with sustainable development, energy conservation, efficiency, and environmental preservation has become highly important. The main purpose of innovative studies on fuel refinement and combustion engines is to improve fuel properties by adding fuel additives. In this study, the impact of Titanium dioxide, TiO2, nanoparticles solution blended with diesel fuel on the performance and emission characteristics of four-stroke combustion engine OM 364 EU III, manufactured by IDEM Co and licensed by Daimler Benz, has been investigated. The selection of TiO2 nanoparticles is based on the easy access in the market and the gap recognized; in previous literature, these nanoparticles were added to biodiesel or n-butanol blends. The proposed combined fuel in this study contains 2.5 ppm TiO2 nanoparticles dissolved in 1200 [ml] water and added to 60 [Lit] base diesel fuel. The results of the aforementioned combined fuel have been compared with the base diesel fuel. It has been observed that applying nano-additives improves the mechanical performance of the diesel engine, such as power, torque, brake-specific fuel consumption, and thermal efficiency. Moreover, soot, unburned hydrocarbons, and carbon monoxide have declined by 2.78%, 3.55%, and 3.32%, respectively, due to TiO2 nanoparticles' catalytic effect on fuel combustion. However, the amount of NOx has increased up to 3.09% because of the high cycle temperature.

“…New ignition methods are among the many options presented in this direction, and HCCI, , PPCI, , and LTC engines have emerged. , Several researchers have also added small proportions of variable types of nanoadditives to the diesel fuel in order to improve combustion characteristics and reduce pollutants. , Some important studies mixed diesel fuel with water to form an emulsion that takes advantage of hydrogen and aqueous oxygen atoms in the combustion. , Since the nineties of the last century until today, studies are continuing to add many types of biofuels to diesel because this fuel is produced from natural sources as it is an oxygenator that contains in its chemical composition oxygen that improves the combustion process inside the combustion chamber. , …”

The operation of engines using rapeseed methyl ester (RME) and ultralow sulfur diesel (ULSD) was tested for the combustion properties, emitted regulated, unregulated exhaust pollutants, and the size of nanoparticles. The combustion analysis showed higher apparent heat release rate and shorter ignition delay period during RME combustion than during ULSD combustion. The ULSD engine has a combustion chamber maximum pressure relatively higher than that of RME. This study showed that the heat release rate of ULSD is always higher than that of RME while more fuel consumption occurred from the combustion of biodiesel in comparison with diesel. When the engine is running on RME, HC and NOx formation increased at high loads up to 15% and 13%, respectively; meanwhile, CO concentrations reduced by 30.9% for the same conditions. Most of the particulate matter (PM) emitted from a diesel engine has a particle size from 5 to 100 nm, while the particle size from ULSD ranged from 5 to 40 nm. Overloading the engine caused a decrease in the sizes of emitted PM for both fuels. The smoke number for RME was less than that for ULSD by 33.9% at high loads. For high engine load, the cumulative concentration number for the nucleation mode decreased, while it increased for the accumulation mode. Furthermore, measurements of formaldehyde, ethane, methane, acetylene, ethylene, propylene, and isocyanic acid emissions showed the presence of these harmful substances at very low concentrations (8 ppm) for both fuels.
