Calculated studies of the influence of the composition and properties of fuel on the working process of the engine have been carried out according to the developed method, includinga computer program for calculating of the working process, models for the flow of fuelin the nose of the fuel nozzle, and the development of fuel steam in the combustion chamber. Regression and graphical dependencies of the specific indicator fuel consumption andspecific emission of nitrogen oxides on the elemental composition, density, viscosity andsurface tension of the diesel fuel are obtained, which allow to evaluate the influence of the above composition and properties on the performance of the process. As a result of the conducted researches, it was concluded that for diesel engines it is better to use buthanol, incomparison with methanol and ethanol, the composition and properties of which provide the best fuel-economic and ecological parameters of the engine.

“…Moreover, with the recent introduction of the ultra-low sulfur diesel (ULSD) more additives are being used to improve other properties as conductivity and lubricity, degraded by the reduction of the sulfur content. 5 Butanol, a product with wide industrial application and produced by petrochemical, fermentative and catalytic routes [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] has recently attracted growing interest from researchers worldwide through its characteristics and potential as alternative fuel. Indeed, several papers in literature have investigated the real feasibility of using butanol as a partial surrogate of traditional petroleum derived fuels.…”

The use of butanol as an oxygenated component in blends with fossil fuels has recently been recognized by the industry as a promising and green alternative for automotive use, being subject of several recent studies. In this work, the interdependence between important physical-chemical properties of butanol/gasoline and butanol/diesel fuel blends was investigated using a multivariate principal component analysis model. The model dataset was based on laboratorial results of density, kinematic viscosity, distillation, vapor pressure, octane rating, anti-knock index, flash point and cetane number in a total of 48 blends, the variables of which were transformed to principal component analysis matrix representations, pre-processed and then analyzed. A good coherence was observed between the experimental results in laboratory and those derived from the principal component analysis models, evidencing important physical-chemical changes in blends’ properties due to the butanol addition. Principal component analysis scores and loadings plots could provide an intuitive and comprehensive data visualization. Butanol/gasoline fuel blends showed an overall increase in density, octane rating and higher distillation temperatures from the initial boiling point to T60 (temperature of the 60% distilled volume) and reduction of the distillation temperatures from T70 to the final boiling point. An absolute reduction in values of all properties was observed for butanol/diesel fuel blends, especially for initial distillation temperatures from initial boiling point to T35, T98, final boiling point and flash point, whereas the reductions for density, kinematic viscosity and cetane number were less intense. Total variances of up to 92.50% and 94.14% were explained by the proposed principal component analysis model, depending on the blends matrix and butanol isomer composition.

“…Studies on butanol-jet fuel blends are limited. Dziegielewski et al [2] studied the compatibility of butanol and bio-butanol blending in Jet-A and diesel fuels, and it was suggested that 10% blending of butanol is acceptable in both Jet A-1 and diesel. They also reported that the blends of butanol reduced the flash point and significantly influenced the conductivity of Jet fuel.…”

The present investigation deals with the puffing and micro-explosion characteristics in the combustion of a single droplet comprising butanol/Jet A-1, acetone-butanol-ethanol (A-B-E)/Jet A-1 blends, and A-B-E. The onset of nucleation, growth of vapor bubble and subsequent breakup of droplet for various fuel blends have been analyzed from the high-speed images. Puffing was observed to be the dominant phenomenon in 30% butanol blend, while micro-explosion was found to be the dominant one in other fuel blends (blend with 50% butanol or 30% A-B-E or 50% A-B-E). It was observed that puffing always preceded the micro-explosion. The probability of micro-explosion in droplets with A-B-E blends was found to be higher than that of butanol blends. Although the rate of bubble growth was almost similar for all butanol and A-B-E blends, the final bubble diameter before the droplet breakup was found to be higher for 50/50 blends than that of 30/70 blends. The occurrence of microexplosion shortened the droplet lifetime, and this effect appeared to be stronger for droplets with 50/50 composition. Micro-explosion led to the ejection of both larger and smaller secondary droplets; however, puffing resulted in relatively smaller secondary droplets compared to micro-explosion.Puffing/micro-explosion were also observed in the secondary droplets.
