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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RÉSUMÉ

Laser Raman scattering method has been applied to measure equivalence ratio of methane/air mixture in injected spray. We used high power KrF excimer laser(λ = 248 nm) and a high gain ICCD camera to capture low intensity Raman signal. Raman shifts and Raman cross-sections of H2, O2, N2, CO2, CH4 and C3H8 are measured precisely. Our results show an excellent agreement with other groups. Mole fraction measurement of O2 and N2 from air shows that O2:N2 = 0.206:0.794.
We used gas injector which is operated at 1 bar. Methane is used as a fuel. Spray region is 10×37 mm and this region is divided into 80 points. 100 Raman signals are obtained and ensemble averaged for each point, 3-d and contour plot of distribution of equivalence ratio is presented. Our measured results show that the equivalence ratio of methane/air mixture in methane-rich region is reasonable. However, more study is necessary for methane-lean region because background noise level is almost same as Raman intensity of methane.
