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

Dual fueling, with respect to compression ignition engines, is a process that allows the utilization of common alternative fuels that have a cetane number too low to be used alone. The alternative fuel requires the retention of diesel injection as a pilot ignition source. Conventional dual fueling pre-mixes the alternative fuel with air in the inlet manifold. However, this causes combustion problems, which limit the amount of fuel that can be substituted for the diesel. An alternative, studied here, is to directly inject both the alternative fuel as well as the original pilot diesel into the combustion chamber.
A purpose-built rig enabled the visualization of fuel jets into the simulated chamber of a diesel engine. Actual tests in an engine were not carried out since the purpose was to use good visualization to obtain details of the injection for modeling. Accordingly, repeatable, millisecond-duration flow visualization of these high-velocity events was essential — work that would have been very difficult in an engine. Jets of both liquid diesel and natural gas were injected into the chamber — first discretely and then with closely staged starting times — and photographed using the shadowgraph and schlieren techniques.
The relative positioning of the injectors for the different fuels with respect to each other as well as their relative timing were then examined and conclusions drawn as to the optimal layout and staging. Using this information, computational models were calibrated. These models formed the basis of computational fluid dynamics simulation of the dual-fuel injection into an actual engine.
