“…244 For this additive, the desired concentration of nanobiochar is blended with the fuel via ultrasonication. 246,247 Further, increasing percentage of nanobiochar additive can provide additional NOx emissions reduction by increasing viscosity of the fuel blend. This, in turn lowers the combustion temperature.…”

“…This, in turn lowers the combustion temperature . The reduction in CO and unburnt hydrocarbons can be attributed to enhanced combustion efficiency of fuel owing to the nanobiochar’s catalytic ability, high surface to volume ratio, and surface area, thus lowering the emission of unburnt particles. , Incomplete combustion is the main cause of unburnt hydrocarbon emissions, which was mainly attributed to the high water content of the fusel oil additive . However, with the addition of nanobiochar, an enhancement in the surface-to-volume ratio of the fuel induced a greater heat transfer rate, thereby aiding in better combustion …”

Nanobiochar is an advanced nanosized biochar with enhanced properties and wide applicability for a variety of modern-day applications. Nanobiochar can be developed easily from bulk biochar through top-down approaches including ball-milling, centrifugation, sonication, and hydrothermal synthesis. Nanobiochar can also be modified or engineered to obtain "engineered nanobiochar" or biochar nanocomposites with enhanced properties and applications. Nanobiochar provides many fold enhancements in surface area (0.4−97-times), pore size (0.1−5.3-times), total pore volume (0.5−48.5-times), and surface functionalities over bulk biochars. These enhancements have given increased contaminant sorption in both aqueous and soil media. Further, nanobiochar has also shown catalytic properties and applications in sensors, additive/fillers, targeted drug delivery, enzyme immobilization, polymer production, etc. The advantages and disadvantages of nanobiochar over bulk biochar are summarized herein, in detail. The processes and mechanisms involved in nanobiochar synthesis and contaminants sorption over nanobiochar are summarized. Finally, future directions and recommendations are suggested.

“…To tackle these issues, fuel additives for effective air‐fuel mixing and atomization must be added (Dharan & Gnanam, 2017; Gad et al., 2020; Hemanandh et al., 2022; Rajamohan et al., 2022). Fuel ignition delay is cetane dependent, high cetane fuel has a shorter ignition delay, which minimizes the fuel combustion process period (Ramachandran et al., 2021).…”

In this work, diesel engine emissions are studied by adding a cetane improver to the engine fuel. Dimethyl carbonate (DMC) additive is used as a cetane improver. A single‐cylinder, four‐stroke diesel engine is used to test the fuels. Three fuels are selected to run the engine, namely, biodiesel derived from neem oil + 1 vol% DMC (BD100 + 1DMC), BD100, and diesel. BD100 + 1DMC fuel emits a reduced amount of carbon monoxide and unburnt hydrocarbons compared to diesel under the same operating conditions of engine. The level of nitrogen oxides emission for BD100 + 1DMC is slightly higher compared to diesel and significantly lower compared to BD100.
