“…The application of ethanol, as a renewable alternative energy in gasoline engine, is matured; however, as it is not mutually soluble with diesel, it has more forms in application in diesel engine, including a small proportion of ethanol mixed with diesel frequently [1][2][3][4], covering pre-mixing or real-time mixing [5]. In case of ethanol injection in the inlet manifold or near the air inlet, it will be ignited by burning diesel [6]; in case of ethanol injection in the inlet manifold or the cylinder, it will be compressed combustion [7,8].…”

Abstract.A set of GDI system is installed on a F188 single-cylinder, air-cooled and direct injection diesel engine, which is used for ethanol injection, with the injection time controlled by the crank angle signal collected by AVL angle encoder. The injection of ethanol amounts to half of the thermal equivalent of an original diesel fuel. A 3D combustion model is established for the ethanol -diesel dual direct injection engine. Diesel was injected from the original fuel injection system, with a fuel supply advance angle of 20°CA. The ethanol was injected into the cylinder during compression process. Diesel injection began after the completion of ethanol injection. Ethanol injection starting point of 240°CA, 260°CA, 280°CA, 300°CA and 319.4°CA were simulated and analyzed. Due to the different timing of ethanol injection, the ignition of the ethanol mixture when diesel fires, results in non-uniform ignition distribution and flame propagation rate, since the distribution and concentration gradients of the ethanol mixture in the cylinder are different, thus affecting the combustion process. The results show that, when ethanol is injected at 319.4°CA, the combustion heat release rate and the pressure rise rate during the initial stage are the highest. Also, the maximum combustion pressure, with a relatively advance phase, is the highest. In case of later initial ethanol injection, the average temperature in the cylinder during the initial combustion period will have a faster rise. In case of initial injection at 319.4°CA, the average temperature in the cylinder is the highest, followed by 240°CA ethanol injection. In the post-combustion stage, the earlier ethanol injection will result in higher average temperature in the cylinder and more complete fuel combustion. The injection of ethanol at 319.4°CA produces earlier and highest NOX emissions.

“…Besides releasing less pollutant such as particulate matter, unburnt hydrocarbon and carbon monoxide, it requires little or no engine modification for usage (Tosun, Yilmaz, Ozcanli & Aydin, 2014). In literature, there are various studies about performance, emission and combustion characteristics of alcohol fueled diesel engines (Datta & Mandal, 2016;Atmanli, 2016;Zhang, Nilsson, Björkholtz, Munch & Denbratt, 2016;Tutak, Lukacs, Szwaja & Bereckzy, 2015;Ali, Abdullah, Mamat & Abdullah, 2015;Li, Zhang & Li, 2016;Wei et al, 2017).…”

To elucidate the relationship between physicochemical properties, spray characteristics, and combustion performance, a series of experiments have been conducted in a constant volume vessel with injection of hydrous ethanol diesel emulsion and regular diesel. HE30 (emulsion with 30% volume fraction of 20% water-containing ethanol and 70% volume fraction of 0# diesel) is developed using Shah's technique and regular diesel is also employed for comparison. Firstly, the physicochemical properties of two kinds of fuels are investigated. Then, the non-evaporating and evaporating spray characteristics are examined through the high-speed shadowgraphs. Finally, spray combustion experiments under different ambient oxygen concentrations are carried out, and color-ratio pyrometry (CRP) is applied to measure the flame temperature and soot concentration (KL) distributions. The results indicate that the physicochemical properties, such as density, surface tension, kinematic viscosity, cetane number, and oxygen content, have significant impact on the spray mixture formation and combustion performance. HE30 exhibits lower soot emissions than that of regular diesel. Further analysis supports the standpoint that the hydrous ethanol diesel emulsion can suppress the soot and NO x simultaneously. Therefore, the hydrous ethanol diesel emulsion has great potential to be an alternative clean energy resource.
