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

RÉSUMÉ

Spray and icing visualization experiments were carried out to investigate spray characteristics and the icing phenomenon of a liquid phase LPG (liquefied petroleum gas) injection (LPLi) system that was intended for use in a modified, medium-duty diesel engine. The spray visualization experiments were conducted for different injection pressures and ambient pressures. Increasing injection pressure was found to benefit spray droplet atomization, enhancing vaporization of the fuel. As a result, the spray penetration length was shortened with increasing injection pressure at atmospheric ambient pressure. However, as the ambient pressure was increased, the penetration length increased with higher injection pressure. The long penetration might result in wall-wetting, causing harmful engine-out emissions such as total hydrocarbon (THC) and CO. It was also observed that ice formed on the nozzle tip and intake port due to the freezing of moisture around the components. This icing phenomenon is the direct cause of unstable engine combustion, resulting in engine emissions. Therefore in this research, the intake air and cylinder head temperatures were changed to investigate the effects of the temperature changes on the icing phenomenon. As a result, both the air and the head temperature increase could reduce the icing phenomenon and the air temperature was more effective.
