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

RESUMO

A new twin-fluid injector applicable to single-point injector for gasoline engine was developed. Transient spray characteristics, mixing mechanism of spray particles and the deposition mechanism on the inner wall of the intake manifold were investigated.
Spray formation by the newly developed single-point injector and the measurements of spray particle sizes, velocities and deposition rates have been conducted in a pulsating air flow. Experiments have been carried out under cold flow condition.
The particle deposition takes place due to particle inertia at high air flow rate. At low air flow rate it takes place clue to the recirculation which appears on the inner wall at the entrance of an intake manifold. On the other hand, the deposition rate of spray particles is strongly influenced by air pulsation. The behavior of spray particle is influenced by the air pulsation at the low velocity of atomizing air and at high velocity of the air flowing around the injector. The small particles follow the air flow more easily than large particles, and this causes the spatial particle size distribution in the spray clump. As the spray particle approaches to the tip of spray clump, the particle size decreases.
