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

RESUMO

The purpose of this study is to compare fuel spray characteristics from mechanical and common-rail systems quantitatively for retrofitting mechanical diesel cars. Outdated diesel cars with mechanical diesel engines emit pollutant emissions and have low fuel efficiency. One of the strategies to retrofit mechanical diesel engine is to adopt a common-rail fuel-supplying system. This strategy has the advantage that it is relatively simple because it only requires the fuel injection system to be changed to a common-rail system, and the other components remain as they are. To consider applying a common-rail system, its effects should be confirmed by comparing the spray characteristics between the mechanical and the common-rail injection system. In this study, we investigated spray visualization, injection rate, and phase Doppler particle analyzer through experiments, and we compared the spray atomization results quantitatively. The results revealed that the spray development of the common-rail injection system is faster than that of a mechanical system using the same injection quantity; also, the spray of the common-rail injection system has a low Sauter mean diameter, and the common-rail system has the added advantage that it provides the ability to independently control various injection conditions, such as adjusting the injection rate by changing injection pressure and energizing time.
