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

An experimental study of the steady-state atomization process of gasoline containing dissolved CO2, is presented. A fuel injection system has been designed to produce a spray having a lower Sauter mean diameter (SMD) than that obtained typically with a direct fuel injection system for the same injection pressure. The downstream part of the injector consists of an inlet orifice, an expansion chamber, a swirl duct, and a discharge orifice. When the mixture enters the expansion chamber, apart of the dissolved gas is transformed into tiny bubbles that grow inside the expansion chamber. When the mixture is driven out through the discharge orifice, these bubbles undergo a rapid flashing process, resulting in a rapid disintegration of the liquid bulk into small droplets. In the present work, we investigate experimentally the effect of the design parameters (geometric proportions, injection pressure, and CO2 content) on the spray characteristics. The spray characteristics (SMD and D90) were measured with a laser particle size analyzer (Malvern X-Mastersizer), and a digital camera was employed to record the spray angle. An overall analysis has been performed to evaluate the advantage of the proposed method over its counterparts, in terms of the total energy required to produce a desired spray. It is concluded that the atomization of gasoline fuel containing dissolved CO2 is significantly promoted by the flash-boiling phenomenon and results in low-SMD and -D90 sprays. It was also found that the spray structure of a fuel/dissolved gas mixture is essentially different from that of a single-component fuel.
