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

ABSTRAKT

The concept of cluster nozzles, grouping multiple smaller holes together, has the potential to improve mixing in the center of the spray and therefore presents an opportunity to lower the production of soot. This concept is characterized by a high number of degrees of freedom concerning the spray orientation, number of spray holes, and configurations of placement of holes in a group. The intention behind the cluster nozzles is to provide a better primary breakup and therefore a better mixture formation caused by the smaller nozzle holes while keeping a comparable penetration length of the vapor phase due to merging of the sprays. Ten cluster nozzles were tested in a single-cylinder engine and compared with a conventional nozzle. Clusters are generally regarded as better than conventional nozzles for partial-load operation. While the results confirm the above notion, they also show some cluster configurations to improve upon the conventional nozzles in high-load conditions. The results show that apart from the orifice size or number in a group, the spatial orientation of the spray is also a critical factor for application in diesel engines. These findings could be helpful for conceptualizing cluster nozzles for applications in the whole operating range of a diesel engine.
