“…dissociate, giving methyl radicals and acetaldehyde, as in reaction (2). This decomposition reaction seems to be very certain, and acetaldehyde has also been found in other studies in quite large The production of molecules like nitromethane also shows that methyl radicals exist in the reactor.…”

“…The amount and chemical composition of exhaust emission is related to the chemical composition of the fuel (7)(8)(9)(10)(11)(12)(13)(14), including the presence of fuel additives (15), but also to the efficiency by which the fuel is combusted. Thus, the selection of fuel, the choice, tuning, and running of the engine as well as the type of exhaust aftertreatment device (16)(17)(18) are important factors for reducing the adverse effects of diesel exhaust emissions (19).…”

Particulate and gaseous exhaust emission phases from running 10 diesel fuels on two makes of heavyduty diesel engines were analyzed with respect to 63 chemical descriptors. Measurements for one of the fuels were also made in the presence of an exhaust aftertreatment device. The variables included 28 polycyclic aromatic compounds (PAC), regulated pollutants (CO, HC, NO x , particles), and 19 other organic and inorganic exhaust emission components. Principal components analysis (PCA) was applied for the statistical exploration of the obtained data. In addition, relationships between chemical (12 variables) and physical (12 variables) parameters of the fuels to the exhaust emissions were derived using partial least squares (PLS) regression. Both PCA and PLS models were derived for the engine makes separately. The PCA showed that the most descriptive exhaust emission factors from these diesel fuels included fluoranthene as a representative of PAC, the regulated pollutants, sulfates, methylated pyrenes, and monoaromatics. Exhaust emissions were significantly decreased in the presence of an exhaust aftertreatment device. Both engine makes exhibited similar patterns of exhaust emissions. Discrepancies were observed for the exhaust emissions of CO 2 and oil-derived soluble organic fractions, owing to differences in engine design. The PLS analysis showed a good correlation of exhaust emission of the regulated pollutants and PAC with the contents of PAC in the fuels and the fuel aromaticity. Also, the emission of soluble sulfate was directly related to the contents of sulfur in the fuels. In conclusion, the PCA clearly indicates that emissions of PAC, particulates, and sulfates are the most descriptive exhaust emission factors. These exhaust emissions can, as shown from the PLS analysis, be much reduced by a decrease of aromatics, PAC, and sulfur in the fuels.

“…Additives supposed to be developed for boosting combustion rates, act as anti-oxidants, affect burn rates, allow fuels to operate at high temperatures, minimise toxic emissions, and more [32]. A tiny amount of several distinct fuel additives is capable of decreasing the nitrogen-oxide emissions, in accordance with experimental findings from a running diesel engine [33]. The Reduxco® additive decreases particulate matter emissions by raising the diffusion combustion rate while marginally increasing the NOx content in engine exhaust flow.…”

Nitrogen dioxide (NO2) is the ubiquitous chemical structure of NOx in the ambience that is initiated by anthropogenic (human) acts. NO2 is also reacts in the surrounding to result in ozone (O3) and the main culprits for acid rain. Captured proportion of NOx by moisture forms acid rain. Acid rain severely affects certain ecosystems. The facts mentioned indicate necessity to reduce NOx pollution. When any of these oxides disintegrate in H2O and breakup, they result in nitric acid (HNO3) or nitrous acid (HNO2). Automobiles is one of the major sources of the NOx that is emitted. Here in this experimental based research effort has been made to reduce emissions of NOx and CO emitted by the diesel based engine powered by Madhuca longifolia as a biodiesel blended with diesel (B10, B20, B30) by injecting water after exhaust gas manifold to get reaction so as oxides disintegrate in H2O and breakup, they result in nitric acid (HNO3) or nitrous acid (HNO2). Experimental work conducted on Mono-cylinder CRDI engine. Trials were taken with different blends of Madhuca longifolia by setting CR 15,16, 17 and 18 with water injected at 3 different mass flow rates (38.7, 82.7, 130.4 CC/min). Results shows average reduction in NOx by 7.89%, 12.26%, and 17.73% respectively.
