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 objective of this study is to gain an enhanced understanding of the characteristics of free spray development, mixture formation, and combustion under high-pressure split injection. The fuel was injected into a constant volume vessel by a single-hole nozzle with a hole diameter of 0.111 mm. The injection process comprised a pre-injection followed by the main injection. The main injection was carried out either as (i) a single main injection, with injection pressure of either 100 MPa or 160 MPa, or (ii) a split main injection with injection pressure of 160 MPa defined by the mass fraction ratio of 75:25. A high-speed camera was used to observe the spray development under non-evaporation conditions. The tracer LAS technique was used to observe the spray mixture formation process. The diesel spray combustion and soot formation processes were studied using a high-speed video camera and examined by two-color pyrometry. The experimental results revealed that split injection can make the vapor phase more homogeneous. Split injection could enhance the combustion and decrease the soot emissions. The soot evolution process was divided into three parts under the single main injection, but into six parts during the split main injection. The effect of the split injection on the soot evolution process ended at the same time when the injection duration is same.
