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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

Краткое описание

Injection strategy determines the air-fuel mixture inside the combustion chamber and hence controls the combustion and emission in direct injection (DI) engines. Higher injection pressure compared to the present-day scenario can be used to improve the in-cylinder air-fuel mixing for gasoline direct injection (GDI) engines. This study presents previously unavailable high-pressure spray characteristics data of n-hexane at nonevaporating and evaporating conditions. Various spray parameters like spray penetration, cone angle, and maximum liquid phase penetration are studied with high injection pressures. Existing correlations of cone angle and liquid length are tuned with the experimental results. The maximum liquid phase temperatures are calculated for evaporating conditions. It is observed that, for an evaporating spray, the maximum liquid phase temperature of the fuel is increased with increase in surrounding gas density for a constant surrounding gas temperature. Air-fuel mixing ratios are also calculated, and the results show that for a constant surrounding gas density, higher injection pressures increase the air-fuel mixing quality at a certain time from the start of injection.
