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 quality of fuel spray plays a vital role in the combustion and emission formation processes in a directinjection (DI) gasoline engine. To fundamentally understand the effects of the airflow on the fuel spray in the combustion chamber in a DI engine the characteristics of the fuel spray in a uniform cross-flow field were experimentally investigated in this study. The fuel was injected by a valve covered orifice nozzle for a DI gasoline engine into an optically accessible rectangular wind tunnel under room temperature and pressure, in which the fuel injection was perpendicular to the orientation of the cross-flow. The velocity of the cross-flow varied from 0 to 9.2 m/s while the injection pressure was 5 and 10 MPa. When the velocity of cross-flow is low, the vertical penetration increases with increasing the injection pressure, while in the case of the horizontal penetration, the distance increases with an increase of the injection pressure and velocity. Empirical correlations were deduced for the temporal variation of vertical penetrations as well asthe variation of spray profile in the upstream side with distance along the cross-flow orientation. The velocity of cross-flow plays a more significant role than the injection pressure on the fuel spray in a cross-flow field. Velocity distributions were measured by a particle image velocimetrysystem, and the results show that the horizontal component of the velocity of the atomized droplet was even higher than that of the cross-flow in the lower region of the spray.
