“…Authors have found a little increase in BTE and BSFC; and except CO emission, other emissions such as NO x , CO 2 , UHC, and smoke increased by using methanol-biodiesel-diesel fuels as compared to diesel. Similarly, with the addition of ethanol with microalgaediesel blends, overall NO x and smoke emissions increased to a great extent that as investigated by Verma et al 25 Jha et al 26 have analyzed the emission characteristics of an old and modified diesel engine fueled by B/D blends and ethanol used as an additive. They observed that NO x and CO emissions were increased with increasing the concentration of ethanol for an old engine, but NO x reduced when fuel samples were used in a modified new engine.…”

Summary The dependence on petroleum has been escalating owing to the proliferation of energy demands and population. Environmental degradation and depletion of petroleum resources are motivated to search the clean energy fuels for diesel engines. Recent studies have been advocated biodiesel as a strong contender to diesel fuel for diesel engines. Despite the significant development in the biodiesel field, there are still issues related to the usage of biodiesel in diesel engines. To overcome these issues, n‐butanol is identified as a biofuel additive that can improve the properties of biodiesel and its blends. The objective of this review is to compare the effect of the butanol–biodiesel (Bu/B), butanol‐biodiesel‐diesel (Bu/B/D), and biodiesel‐diesel (B/D) blends on the performance, combustion, and emission characteristics of diesel engines. Performance characteristics for Bu/B/D blends were observed remarkable than Bu/B and B/D blends, however, slightly inferior to diesel fuel. Combustion parameters of Bu/B/D blends were analogous to B/D blends however superior to Bu/B. Emission characteristics were reduced to a great extent with Bu/B/D blends as compared to all other sample fuels. This article also analyses the overview of biobutanol production from lignocellulosic biomass by acetone‐butanol‐ethanol fermentation process. Finally, this study reports that butanol has the potential, which can help to sustain engine performance and mitigate emissions. Among all the Bu/B, Bu/B/D, and B/D blends, Bu/B/D blends provide better fuel quality and significant results from the diesel engine characteristics; however, up to 20% blending of butanol with B/D blends showed better results after that engine performance decreased.

In this study, the effects of adding ethanol and diethyl ether to diesel fuel on combustion characteristics and NO emissions were numerically investigated. 100% diesel fuel (D100) and by volume 90% diesel+10% ethanol blend (D90E10), 80% diesel+20% ethanol blend (D80E20), 80% diesel+10% ethanol+10% diethyl ether blend (D80E10DEE10) and 85% diesel+ 10% ethanol+5% diethyl ether mixture (D85E10DEE5) was used as fuel. Analyzes were carried out using a single cylinder direct injection diesel engine at 2000 and 3000 rpm engine speed conditions. AVL FIRE software was used for numerical study. In-cylinder pressure, cumulative heat release rate, turbulent kinetic energy (TKE), NO emissions and velocity distributions in the combustion chamber were investigated for five different fuel types. As a result, the in-cylinder pressure and heat release rate of ethanol and diethyl ether blended fuels were lower than diesel fuel at both speeds. This is due to the calorific value of the fuel. It was observed that NO emissions decreased as the ethanol content in the fuel increased. For both engine speeds, the highest TKE value was obtained in D90E10 mixed fuel, and the lowest value was found in D80E10DEE10 mixture fuel. Ethanol positively affected the turbulent kinetic energy. The flow rate of ethanol was higher than diesel and diethyl ether fuel.

“…The quantity of NO x created by M100 is also minimized owing to its elevated latent heat of vaporization ( LHV ) that drops the combustion temperature. Additional constraints of M100 as an alternative for diesel fuel comprise its less heating value ( HV ) and combination constancy concerns while it is mixed with fuel 9 , 10 .…”

“…They mentioned that the bsfc for the mixtures was smaller than diesel fuel, while NO x increased, and CO lowered. Verma et al 10 assessed the engine performance run with ethanol (20%)/methanol(20%)/diesel/microalgae mixtures. They mentioned that the in-cylinder pressure increased for the mixture compared to diesel fuel.…”

This research endeavored to boost the applicability of methanol in CI engines utilizing n-decanol as cosolvents. The work was split into binary phases. Firstly, the stabilities of pure methanol (M100) and hydrous-methanol (MH10), with diesel as a reference fuel, were examined applying various temperatures: 10 °C, 20 °C, and 30 °C. The findings showed that the M100-diesel and MH10-diesel combinations were unstable. Thus, n-decanol was utilized as a cosolvent. Following by the engine combustion and emissions characteristics were evaluated by manipulating three proportions of M100-diesel mixtures with n-decanol. Three mixtures comprised of 5, 10, and 15% M100 with 20% n-decanol, which are denoted as M5, M10, and M15, correspondingly. These combinations were assessed via thermogravimetric assessment, and their physicochemical properties were assessed corresponding to the ASTM. The maximum in-cylinder pressure, heat release rate, and pressure rise rate diminished by 10, 11, and 10%, respectively, for the M100/diesel/n-decanol combinations compared with the diesel oil. The brake thermal efficiency lowered by 10%, whereas the brake specific fuel consumption enlarged by 10% for the combinations compared with the diesel. NOx and smoke opacity levels diminished by about 30 and 50%, respectively, whereas the CO and UHC enlarged by about 50 and 60% for the blends compared with the diesel oil.
