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

Краткое описание

The atomization quality of liquid fuel entering the cylinder of a port-injected, spark-ignition engine was measured and the effects of the air velocity in the port, the injection timing, the injector spray quality, and the amount of injected fuel are discussed. From an analysis of the data rates, estimates of the relative rates of fuel accumulation in the port were made. The Sauter mean diameter (SMD) of the incoming droplets and the rate of fuel accumulation in the port may be reduced significantly by increasing the air velocity in the intake port. Injector spray quality affects the sizes of droplets entering the cylinder for open-valve injection timing but not for closed-valve timing. Doubling the amount of injected fuel results in a modest increase in SMD of the spray entering the cylinder.
