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

ABSTRACT

The present study deals with the spray development and atomization with a wide range of injection pressure and injection timing in a Gasoline Direct Injection (GDI) system. A wide range of injection pressure was swiped from 5 MPa to 30 MPa to investigate the effect of injection pressure on spray behaviors. The macroscopic spray images taken by a high-speed camera were used to investigate the influence of the injection pressure on the spray development process. Spray tip penetration, cone angle, and spray tip velocity were measured from the spray images, and the breakup regimes were predicted using dimensional analysis. Experimental results showed that an increase in injection pressure caused a decrease in droplet size based on the sequential spray images and breakup regimes. However, for injection pressures over 20 MPa, the effect of injection pressure on spray characteristics was minimal with the injection pressure increase. Meanwhile, the spray images in the GDI engine revealed that injection timing was directly related to the air−fuel mixture homogeneity. Strong intake flow broke up the spray structure and mixed the fuel with the air effectively. This study proposes a proper injection pressure range for GDI injection systems, and the results in the present study would be helpful in comprehending gasoline spray characteristics.
