“…In recent years, with aggravating energy consumption and challenging fuel consumption regulations, the attention is increasingly focused on exploring renewable clean alternative fuels, such as alcohols [5][6][7], ethers [8][9][10], esters [11][12][13], and natural gas [14,15]. As a renewable substitute for diesel, the n-butanol has drawn extensive interest owing to its prominent fuel properties [16][17][18] compared to ethanol and methanol. Produced from the biomass feedstock fermentation process, n-butanol is confirmed as a biomass-based renewable fuel [19][20][21].…”

“…Another factor also influencing CO emissions is carbon content. The carbon content in n-butanol is ~64.9%, and for diesel, it is ~86.4% on a mass basis, which also can lead a lower energy level for n-butanol based fuel and lower CO emission [2].…”

“…This research work primarily deals with the utilisation of alcohol-based fuels in diesel engines because they are considered as bio-oxygenated compounds with low viscosity, high volatility and miscibility with diesel. In alcoholic based fuels, butanol is the most suitable substitute for diesel engines compared to ethanol because of its maximum energy density, less corrosive nature and less prone to contamination in the presence of water content [2]. This fuel is also considered a clean alternative source for fossil fuels to reduce greenhouse emissions.…”

This research work indicates the analysis conducted to investigate the performance, exhaust emission and combustion characteristics of a VCR diesel engine fuelled with nbutanol blends at a rated speed of 1500 rpm with 300 bar injection pressure at compression ratios of 16, 18 and 20. The test fuel was prepared by adding n-butanol 10% (NB10) and 20% (NB20) to diesel by volume. The combustion characteristics investigated were; rise in-cylinder pressures, net heat release rate, cumulative heat release rate and mass fraction of fuel burned at all loads using three compression ratios. The emission and performance study also conducted. The higher heat release rates, increased cylinder pressures were observed for both the blends compared to diesel. Increased brake thermal efficiency observed at higher compression ratio for NB20 blend. It had also been observed that the emissions of CO2, HC and NOx were increased for both the blends, while CO emissions decreased in trend with an increase in compression ratio and blend strength.

“…It was found that the DDF with the two bio-alcohol blends, with ignition combining cooled EGR and supercharging improved the NOx and smoke emission trade-off relation substantially while maintaining relatively high values in the brake thermal efficiency. Recently, a number of studies with next generation bio-alcohol blended fuels have been carried out targeting diesel operation (Han et al, 2016;Ileri, 2016;Kumar and Saravanan, 2016;Imdadul et al, 2017;Saravanan et al, 2017;Anil Bhaurao et al, 2018;Killol et al, 2019;Pan et al, 2019). But, many of these studies have been conducted with nbutanol, iso-butanol, or n-pentanol, and there are few reports with iso-pentanol (Yoshimoto et al, 2018b).…”

Studies in diesel dual fuel operation (DDF), introducing compressed natural gas (CNG) from the intake pipe and ignited by a liquid fuel injection in the combustion chamber have been conducted with conventional diesel engines. The present study investigated the effects of trade-off improvements between NOx and smoke emissions with next generation bio-alcohol blended FAME fuel ignition in DDF with a combination of EGR and supercharging. The CNG supply rates were set at 0% (diesel operation) and at 41-44% (DDF) on a heat energy basis, the boost pressures were set to two conditions with supercharger operation: 100 kPa (naturally aspirated operation, N/A) or 120 kPa (supercharged operation, S/C), and the EGR rates were varied from 0 to 25%. Blended fuels with a base fuel vs. alcohol ratio of 7: 3 were prepared using what in the following is termed PLME containing equal proportions of methyl palmitate (PME) and methyl laurate (LME) as the base fuel. The next generation bio-alcohols used here were iso-pentanol (C5) and iso-butanol (C4), and the engine performance, combustion characteristics, and exhaust emissions were investigated with iso-pentanol blended PLME (termed PLiP30), iso-butanol blended PLME (PLiB30), and neat PLME, as the ignition fuel. The results showed that with all ignition fuels, the DDF combining cooled EGR and supercharging improved the trade-off relation between NOx and smoke emissions significantly while maintaining relatively high brake thermal efficiencies.
