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 goal of this study was to investigate the effects of injector characteristics and injection timing on fuel mass delivery to the valve in a fired spark ignition engine. The relationship between injection timing and fuel arrival at the intake valve must be known for designing an injection system for increased liquid entrainment into the gas phase and minimized fuel wetting of the port walls. Fuel spray behavior from a conventional injector design and prototype vacuum-assist and air-assist injector designs is investigated by measuring fuel drop size and velocity at the intake valve using phase Doppler interferometry. The results of this study indicate the amount of time required for the fuel spray to reach the intake valve is constant and independent of injection timing. However, the width of the temporal fuel spray arrival distribution is a strong function of injection timing. Injection timing and the corresponding gas-phase dynamics have the strongest impact on the smallest drops, resulting in a redistribution of the drops with respect to size. In addition, the fuel spray behavior was investigated at the start of the intake valve event when hot cylinder gases flow into the intake port. The arithmetic mean diameter of the fuel film atomized off the back of the intake valve during this period was found to range from 55 to 65 μm.
