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 transient characteristics of high-injection-pressure diesel fuel sprays have been investigated by high-speed photography. An off-engine fuel injection system with a hydraulic unit injector was designed for spray visualization experiments. Experiments were conducted using different geometry nozzles under different operating conditions to investigate the effects of injection pressure, nozzle inlet condition, nozzle injection angle, and nozzle hole size on spray characteristics. Measurement of spray tip penetration length and spray angle were made based on the spray images. The Sauter mean diameter (SMD) averaged over the spray was measured using a light extinction method. The results of these experiments show that spray geometry ( penetration length and cone angle) is sensitive to small changes in operating conditions and injector geometry. Higher injection pressures produced larger penetration, smaller spray cone angles, and smaller overall average SMD. Smaller nozzle hole sizes and smaller injection angle nozzles also produced smaller droplet sizes.
Previous results from engine emissions tests using the same injector under similar operating conditions were examined in light of the observed spray characteristics. While the engine emission results are affected by many parameters related to the fuel injection system as well as many which are unrelated to the injection system, the results of these comparisons indicate that spray SMD and spatial distribution have a significant effect on engine emissions for the conditions tested.
