“…From the literature review, it is clear that most of the research work on ethanol has been done on blend with diesel [4][5][6][7][8][9] and [16][17][18]. Although many publications on dual fuel engines can be found in the literature, it seems that the topic has not been exhausted.…”

The paper presents results of experimental investigation of co-combustion of fuels of various reactivity at dual fuel Diesel engine. The tested fuels were ethanol fuel (EF) and diesel. It was used one-cylinder direct injection Diesel engine. Researches were conducted at constant rotational speed and constant injection timing. With the increase in EF fraction the deterioration of combustion process was indicated. On the basis of heat release variation were determined combustion phases: ignition delay, combustion duration. With the increase in EF participation in combustion processes the IMEP increased as well. There was no noticeable effect of ethanol on unrepeatability of indicated mean effective pressure. The increase in EF fraction causes the specific NO x emission decreases but specific total hydrocarbon emission increased.

“…This could be explained by the delayed combustion of the pilot injection. By contrast, other authors [60] found that the higher the presence of ethanol in the blend, the lower the combustion noise, this being due to the decrease of the cylinder pressure and heat release rates. Heuser et al [61] demonstrated that high ethanol shares showed worse combustion noise at low load than at high load.…”

The growing demand for fossil fuels, the rise in their price and many environmental concerns strengthen the incessant search for fuel alternatives. Recently, traffic noise has been described as a threat to human health and the environment, being responsible for premature deaths. In this context, the usage of alcohol/diesel fuel blends in diesel engines has gained increasing impact as a substitute fuel for use in internal combustion engines. Moreover, alcohol can be derived from environmentally friendly processes, i.e., fermentation. Furthermore, alcohols can enhance combustion characteristics due to a rise of the oxygen concentration, thus decreasing major emissions such as soot and reducing knock. The commonly used alcohols blended with diesel fuel are methanol and ethanol, recently followed by butanol. In contrast, there are very few studies about propanol blends; however, emissions reduction (including noise) could be remarkable. In the present work, an analytical literature review about noise and exhaust emissions from alcohol/diesel fuel blends was performed. The literature review analysis revealed a continuous increase in the number of publications about alcohol/diesel fuel blend exhaust emissions since 2000, confirming the growing interest in this field. However, only few publications about noise emission were found. Then, an experimental case study of noise emitted by an engine running on different alcohol (ethanol, butanol and propanol)/diesel fuel blends was presented. Experimental results showed that although diesel fuel provided the best results regarding noise emissions, butanol displayed the least deviation from that of diesel fuel among all tested alcohol blends. It may be concluded that tested alcohol/diesel fuel blends in general, and butanol blends in particular, could be a promising alternative to diesel fuel, considering noise behavior.

“…An active interest, shown in the last 5-7 years in the studies of integral characteristics of the interaction of colliding liquid drops in a gas medium, is conditioned by the main objective, namely to identify the key mechanisms and to search for the regimes of controlling these processes in many modern promising technologies, e.g., fuel combustion in IC engines [1][2][3], fire-fighting [4], pharmaceuticals production [5], application of aerosol systems to determine the level of air pollution [6], etc. The objects of such studies include both homogeneous and two, three and multi-component drops of solutions, slurries, and emulsions.…”

The study of the characteristics of secondary droplet atomization, leading to formation of an aerosol cloud of polydisperse child droplets appears to be promising. It is topical to assess the influence of properties of liquid and gas medium on the position of transition boundaries between the regimes of drop collisions and characteristics of the formed child droplets. This article presents the experimental results for the characteristics of drop collisions at various temperatures of the liquid and gas-vapor mixture and water vapor concentration in the latter with the aim of developing the prospective heat and mass transfer gas-vapor technologies. For this purpose, we have created the experimental setup that allows varying the relative humidity of gas-vapor mixture in the area of drop collisions from 20% to 100%, its temperature from 20?C to 100?C and the temperature of the liquid from 20?C to 90?C. The test fluid is water. The collisions are recorded by a high-speed video camera. The consequences of collision and the boundaries between them on the regime maps are determined in accordance using the approach, distinguishing: bounce, coalescence, separation, and disruption.
