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

SINOPSIS

The authors have proposed a novel approach regarding fuel design methodology targeting both diesel and gasoline engines and demonstrated that the fuels designed based on this approach were effective in achieving high thermal efficiency and low pollutant emissions. Flash boiling spray is applied to improve the spray atomization and evaporation processes by using several kinds of mixed fuels with relatively low injection pressure. This paper is a review concerning our previous research and new experimental results of superheated mixed diesel-like spray, focusing on spray dynamics. In the mixed fuels, additives or lower boiling point fuels such as CO2, gas fuel, and gasoline component, are mixed into a higher boiling point fuel such as diesel gas oil, through vapor-liquid equilibrium with a formation of a two-phase region in a pressure-temperature diagram, where liquid and vapor phases of both components are mixed in. In this scheme, the authors intend to control both the physical process, that is, the fuel vapor formation rate or spatial vapor distribution, and chemical processes, which are the mixture ignition, emission reduction of NOx and PM, and HC burnout. Then it is easy for mixed fuel to readily undergo flash boiling spray due to the formation of a two-phase region on a P-T diagram, providing as well as a relatively lean and homogeneous vapor mixture. In the experiments, the authors conducted mixed fuel application studies for the actual diesel combustion field by use of mixed fuel consisting of liquefied CO2 as an additive with n-tridecane as a typical component of diesel gas oil, and mixed fuel of gas or gasoline component with a diesel gas oil component to control the evaporation process. Furthermore, experiments of mixed fuel heating were conducted to realize the prompt evaporating spray due to a partial flashing effect and a supercritical diesel-like spray feature.
