The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00095 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

SINOPSIS

The spray characteristics were investigated for the Diesel-methanol-water (DMW) emulsion and commercial Diesel fuel. Droplet diameters and droplet size distributions were measured by Malvern particle size analyzer and spray tip penetration, and cone angles were acquired using the high-speed CCD digital camera. All experiments were conducted by employing a high-pressure fuel injection system under room temperature and pressure. The viscosity property of the experimental liquid was measured by the rotary viscometer to ensure the influence of the liquid physical property on spray characteristics. The changes of the emulsion physical properties, including the dispersed phase content and the emulsifier, caused significant changes of the spray characteristics. It was found that the curve of droplet size distribution of DMW emulsion and Diesel first increased then decreased with the increase of the nominal diameter, but the distribution range of Diesel was narrower than that of DMW emulsion. Furthermore, Sauter mean diameter and other representative drop diameters decreased with the increase of injection pressure, and a higher injection pressure produced finer spray droplets and better distribution uniformity. Under the same conditions, the spray tip penetration and cone angle of DMW emulsion were smaller than that of Diesel, and they decreased with the increase of the dispersed phase content. Meanwhile, a higher viscosity and lower HLB of the emulsifier had a larger atomized particle size and a smaller spray tip penetration and spray cone angle. However, the variation of spray characteristics of different fuels became smaller with increasing injection pressure.
