“…Recently, Nanthagopal et al (2018a) for 10, 20, and 30% pentanol/CIME and Nanthagopal et al (2018b) for 40, 50, and 60% pentanol/CIME found that the CO, HC, and soot emissions are higher compared to those for neat CIME and lower than those for diesel fuel, while NOx emissions are higher than those for diesel fuel and lower than those for neat CIME for all engine loads. The addition of n-pentanol of more than 40% to diesel showed a negative effect in terms of performance and combustion, and thus, among all blends, B90P10 in the case of CIME was found to show better performance and emission characteristics (Ashok et al, 2019).…”

Of several higher alcohols such as pentanol, hexanol, octanol, decanol, dodecanol, phytol, and fusel oil, pentanol isomers have recently received remarkable attention as alternative fuels for diesel engines because they emit less greenhouse gases and harmful pollutants. Because of great potential as a blending component and physicochemical properties of pentanol, binary blends such as diesel/pentanol and biodiesel/pentanol and ternary blends such as diesel/biodiesel/pentanol were mainly studied in the conventional diesel engine. Quaternary blends of diesel, biodiesel, straight vegetable oil, and pentanol were also investigated. Very few information related to the application of pentanol to advanced compression ignition (CI) engine is available in the literature. The diesel/pentanol blends coupled with exhaust gas recirculation (EGR) technology could simultaneously reduce NOx and soot emissions from CI engine. Further, diesel/pentanol blends generally produced higher CO and hydrocarbon (HC) emissions than did diesel fuel. However, CO and HC emissions were significantly reduced by mixing the cetane improver with the blends. Up to 45-50% n-pentanol/diesel blends can be safely used in diesel engines without any engine modification or any additive. However, in terms of kinematic viscosity, lubricity, and oxidation stability of diesel/pentanol blends, the use of pentanol should be limited to concentrations below 10%. Generally, in the studies of biodiesel/pentanol blends in CI engines, the reduction of CO, HC, NOx, and smoke emissions was observed compared to neat biodiesel. For ternary blends, diesel/biodiesel/pentanol blends were mainly investigated by the researchers. The emission characteristics in terms of CO, HC, NOx, and smoke opacity showed the different trends according to the pentanol proportion in the ternary blends, particularly <10% or more than 10%. To increase the biofuels in the CI engine, more studies for the quaternary blends of pentanol are required.

“…It can be attributed to the combined impact of the LHV and the quality of the ignition of the tested alcohols [84]. The higher LHV (as seen in Table 1) causes to retract the heat from the combustion chamber, i.e., quenching effect inside the cylinder [87].…”

D iesel engines or CI engines have been taken into consideration to be a vital and important power source all over the world for various areas such as transportation (land, air, and sea), agriculture, power generation, industrial activities, and construction engineering sectors because they have high-performance features [1][2][3]. Diesel engines possess also capacity in terms of supplying higher torque, higher power outcome, higher durability and supe-Article History:

“…NO and smoke emissions were reduced, but CO and UBHC emissions increased for biodiesel-higher alcohol blends. Ashok et al 21 investigated the effect of biodiesel-n-pentanol blends on diesel engine characteristics. Addition of n-pentanol to biodiesel improved thermal efficiency and reduced UBHC and CO emission by about 15-43% and 33-50%, respectively, compared to pure biodiesel.…”
