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

摘要

Maximum benefits from gasoline direct-injection systems can only be achieved by precisely controlling the atomization and evaporation processes of the fuel within the cylinder of an internal combustion engine. These requirements place considerable demands on the fuel injection hardware, in particular the injector. In addition the variable conditions of fuel properties, fuel temperature, and in-cylinder pressure interact to affect the fuel spray formation and development. This work seeks to understand and quantify these interactions and their working mechanisms for the latest generation of direct-injection gasoline multihole injectors by examining the fuel spray in a static rig in which each of these parameters can be independently altered. Five types of fuels with different grades of volatility were studied for a range of fuel temperatures (20−120° C) and gas pressures (0.55.0 bar). The fuels included various grades of gasoline, iso-octane, and a multicomponent model fuel blended specifically to mimic gasoline but also suitable for in-cylinder laser-induced fluorescence measurements. The fuel pressure was kept constant at 150 bar throughout the experiments. Measurements of key spray parameters (such as plume penetration and cone angle) showed that the main mechanism affecting spray development in a quiescent environment was dependent on the amount of superheat of the lowest volatility components in the fuel for the prevailing gas pressure and fuel temperature conditions. A high amount of superheat led to the rapid and disruptive, near-spontaneous, vaporization of the fuel as it was ejected from the nozzle. The migration of fuel vapor to the low-pressure regions between the spray plumes acted to draw the plumes together to form a single, high-penetration-rate plume in the extreme case. This contraction of the global spray form has been termed "spray collapse." The lack of high superheat and the single boiling point of iso-octane was manifested in markedly different, less collapsed spray form, which carries implications when characterizing an engine or injector using only such a single-component model fuel. The variability of the fuel spray from injection to injection was not affected appreciably by operating conditions, suggesting a certain level of "random" small variability due to the injection event and spray breakup itself, or from injector internal effects.
