“…Sathish Kumar et al, in another work, experimented with a direct injection (DI) diesel engine powered with sapota biodiesel and diesel at various blend proportions, viz., B25, B50, B75, and B100, and the results showed that the B50 blend recorded a maximum brake thermal efficiency (BTE) and reduced carbon monoxide (CO), unburned hydrocarbon (UHC), and CO 2 emissions compared to other test fuels, while NO x emission for biodiesel blends was on the higher side against baseline diesel. Pocharedd Pochareddy et al stated that CO, UHC, and smoke emissions decreased and NO x emissions, brake thermal efficiency, and exhaust gas temperature increased simultaneously owing to the addition of sapota biodiesel ratio in the blend.…”

The enthusiasm for biofuels as feasible alternatives for use in diesel engines has significantly expanded on account of their spotless consuming nature in addition to fossil fuel independence. The present study utilizes two oxygenates, dimethyl carbonate (DMC) and n-butanol (n-B), derived from non-food-based lignocellulosic biomass in a blended form with transesterified oil extracted from waste sapota seeds to power a modern one-cylinder common rail direct injection (CRDi) diesel engine for any improvement in combustion, performance, and emission characteristics. Three test fuels, viz., B40%, B40% + DMC10%, and B40% + n-B10%, were prepared by splash blending, and the results were correlated with baseline diesel fuel. The experimental results indicate that accrual of oxygenates to sapota oil methyl ester has improved the combustion characteristics in comparison to diesel and B40% + n-B10%: the peak heat release rate (HRR) for B40% + DMC10% was 4.89 and 5.14% higher, respectively. The brake thermal efficiency (BTE) of an engine fueled with a B40% + DMC10% blend was better than that fueled with B40% + n-B10% but lower than that fueled with baseline diesel. The oxides of nitrogen (NO x ) emission were higher side when the engine was fueled with both oxygenated blends compared to diesel: B40% + DMC10% exhibits 6 and 2% higher values than diesel and B40% + n-B10%, respectively, at peak load conditions. Smoke opacity experienced a sharp reduction when fueled with a B40% + n-B10% blend; there was about 11.76, 19.60, and 23.52% reduction when fueled with diesel, B40%, and B40% + DMC%, respectively. Carbon monoxide for B40% + DMC10% was the lowest compared to diesel, B40%, and B40% + n-B10%, and there were about 21.59, 86.85, and 34.74% reduction in emissions, respectively. Hydrocarbon emission for B40% + DMC10% was the lowest compared to diesel, B40%, and B40% + n-B10%, and there were about 8.62, 27.58, and 17.24% reduction in emissions. Reformulation of diesel with DMC, n-butanol, and sapota oil methyl ester renders a chance to decrease emissions and use renewable fuel in diesel engines.

“…Moreover, with the addition of 5%DEE to B20 fuel, CO emissions are reduced by almost half compared to when using diesel fuel at the same test condition. Pochareddy et al (Pochareddy et al, 2017) studied the emission characteristics of CI engines using fuel mixed by sapote seed oil methyl ester, 5%DEE and diesel. It can be found that CO, smoke and HC emissions are significantly reduced compared to pure diesel fuel, while exhaust gas temperature and NOx emissions increase.…”

Pressure on alternative fuels and strict environmental regulations are driving a strategic shift in the efficient use of renewable biofuels. One of the promising biofuel candidates recently interested by scholars is a biological or organic additive that is added into diesel or biodiesel fuel to improve engine performance and reduce pollutant emissions. With efforts to improve efficiency and combustion quality in cylinders, combustion characteristics, flame structure and emission formation mechanism in compression ignition (CI) engines using blended fuel with organic additives have been studied on the effect of additive properties on the combustion behaviour. In this review, the physicochemical properties of typical organic additives such as ethers compounds and their effects on engine performance and emission characteristics have been discussed and evaluated based on conclusions of recent relevant literature. The results of the analysis revealed the prospect of using ether additives to improve combustion in cylinders and reduce pollutant emissions from CI engines. Obviously, the presence of higher oxygen content, lower viscosity and density, and higher cetane number resulted in a positive change in the combustion dynamics as well as a chain of mechanisms for the formation of pollutant precursors in the cylinder. Therefore, ether additives have a significant contribution to the sustainable energy strategy of the transportation sector in the next period when internal combustion engines still dominate in the competition for energy system choices equipped on vehicles.

“…Bio-diesels were proposed as an alternative to diesel whereas oxygenates such as methanol, ethanol etc. were proposed as an alternative to gasoline, to tackle fossil fuel depletion and pollution related problems [2][3][4][5]. Among the diversified alternatives to gasoline, some are reviewed and discussed as follows: Agarwal et al [6] on testing methanol/gasoline blends in a fourcylinder engine found that with the use of methanol substituted gasoline blends, BTE, NO and CO emissions improved, with slight irregularities in HC emissions.…”

a b s t r a c tWith growing concerns about environmental pollution caused by automobiles, biofuels containing oxygen -also known as oxygenates -are being researched very rigorously. In this article, we have inspected the use of isopropanol/gasoline blends, as fuel in a 4 -cylinder Spark Ignition engine with Multi-Point Fuel Injection System. Isopropanol was mixed with Unleaded Gasoline in proportions of 10, 20 and 30% by volume (IPA10, IPA20 and IPA30). It is found that with the use of isopropanol/gasoline blends in Spark Ignition Engine, Brake Thermal Efficiency and NOx emissions increased whereas carbon monoxide and hydrocarbon emissions decreased. When the spark timing was retarded by 2 degrees, it was found that isopropanol/gasoline blends emitted lower NOx emissions than those at original spark timing. Isopropanol blends also increased the in-cylinder pressure values and heat release rate values. Ó 2016 Karabuk University. Publishing services by Elsevier B.V.
