“…An experimental study has been devoted by Beatrice et al in [91] to the characterization of an Euro 5 automotive CI engine, fueled by blend fuel consisting in 20 vol% bio-ethanol, 10 vol% rapeseed methyl ester, and 70 vol% fossil diesel underlining the impacts of bio-ethanol use. Emission measurements for an Euro 5 CI engine indicated the well-known effects of ethanol blending to petroleum diesel fuel: an important reduction of smoke in all tested conditions, NO x reduction, and an increase of CO and HC, especially at low load conditions, compared with the B10 fueled engine.…”

The use of alternative fuels contributes to the lowering of the carbon footprint of the internal combustion engine. Biofuels are the most important kinds of alternative fuels. Currently, thanks to the new manufacturing processes of biofuels, there is potential to decrease greenhouse gas (GHG) emissions, compared to fossil fuels, on a well-to-wheel basis. Amongst the most prominent alternative fuels to be used in mixtures/blends with fossil fuels in internal combustion (IC) engines are biodiesel, bioethanol, and biomethanol. With this perspective, considerable attention has been given to biodiesel and petroleum diesel fuel blends in compression ignition (CI) engines. Many studies have been conducted to assess the impacts of biodiesel use on engine operation. The addition of alcohols such as methanol and ethanol is also practised in biodiesel–diesel blends, due to their miscibility with the pure biodiesel. Alcohols improve the physico-chemical properties of biodiesel–diesel blends, which lead to improved CI engine operation. This review paper discusses some results of recent studies on biodiesel, bioethanol, and biomethanol production, their physicochemical properties, and also, on the influence of the use of diesel–biodiesel–alcohols blends in CI engines: combustion characteristics, performance, and emissions.

“…In [20], the solubility of EBD blend was investigated at two different temperatures, which showed that the solubility of ethanol increased when increasing the temperature. Beatrice et al [21] studied the influence of blending 10% biodiesel, 20% ethanol, and 70% diesel fuels on ICE performance. In the latter study, the smoke and Nitrogen Oxides (NO X ) emissions were found to be significantly less than those of pure diesel.…”

The Impact of Biodiesel Fuel on Ethanol/Diesel Blends

2019

The interest in biofuels was stimulated by the fossil fuel depletion and global warming. This work focuses on the impact of biodiesel fuel on ethanol/diesel (ED) fuel blends. The soybean methyl ester was used as a representative composition of typical biodiesel fuels. The heating and evaporation of ethanol–biodiesel–diesel (EBD) blends were investigated using the Discrete–Component (DC) model. The Cetane Number (CN) of the EBD blends was predicted based on the individual hydrocarbon contributions in the mixture. The mixture viscosity was predicted using the Universal Quasi-Chemical Functional group Activity Coefficients and Viscosity (UNIFAC–VISCO) method, and the lower heating value of the mixture was predicted based on the volume fractions and density of species and blends. Results revealed that a mixture of up to 15% biodiesel, 5% ethanol, and 80% diesel fuels had led to small variations in droplet lifetime, CN, viscosity, and heating value of pure diesel, with less than 1.2%, 0.2%, 2%, and 2.2% reduction in those values, respectively.

“…In addition, RME contains no aromatics, which are contributors to engine particulate emission [8,9]. Because of its approximately 10% [10,11] oxygen content, low sulfur content, zero aromatics content, and higher cetane number, RME has been found to be able to lower PM (Particulate Matter) emission, although with possible penalty of higher NO x emission [12].…”

Effects of Oxygen Content of Fuels on Combustion and Emissions of Diesel Engines

et al. 2016

Effects of oxygen content of fuels on combustion characteristics and emissions were investigated on both an optical single cylinder direct injection (DI) diesel engine and a multi-cylinder engine. Three fuels were derived from conventional diesel fuel (Finnish City diesel summer grade) by blending Rapeseed Methyl Ester (RME) or Diglyme and Butyl-Diglyme of different quantities to make their oxygen content 3%, 3% and 9%, respectively. The experimental results with three tested fuels show that the fuel spray development was not affected apparently by the oxygenating. Compared with the base fuel, the ignition delay to pilot injection was shortened by 0%, 11% and 19% for three oxygenated fuels, respectively. The ignition delay to main injection was shortened by 10%, 19% and 38%, respectively. With regard to emissions, the smoke level was reduced by 24% to 90%, depending on fuel properties and engine running conditions. The penalties of increased NO x emissions and fuel consumption were up to 19% and 24%, respectively.
