1.1 Submitted articles should correspond to the journal profile. Scientific articles, which have such necessary elements, are accepted for publication: introduction, analysis of literature data and problem statement, aim and objectives of research, research results, discussion of study results and conclusions.

The Editorial Board accepts articles that consider the current state of the most pressing problems related to the journal's profile.

1.2 The minimum size of the article – 8 thousand characters including spaces (3 full pages of typed text), the maximum – 30 thousand (up to 12 pages of typed text). The recommended article size is 15-22 thousand characters (5-10 pages of typed text).

Illustration is indicated by the word "figure __", which together with the name of the illustration is placed after the explanatory data. Picture title: font "Times New Roman", size 11 points, normal, placement in the centre of the page. All illustrations should be referenced in the text!!!

Figures are attached to the article in the form of graphic files. It is best if the illustrations are made using vector graphics and saved in JPG format.

Author, A. A. Author, B. B., & Author, C. C. (2005). Title of the article. Title of Journal, 10(2), 49-53.

If a bibliographic source has a unique identifier DOI (Digital Object Identifier), which is used by almost all leading foreign journals to identify their articles, it is desirable to specify it in the list of references.

2.9 After one line, information about the authors is recorded. Surname, first name, patronymic of the author, scientific degree, academic title, position and main place of work, e-mail of the author and ORCID. Data about each of the authors is recorded from a new line.

 In the paper, a new method of fractal diagnostics of the quality of the fuel spray injector the diesel engine is proposed. The original technique that allows you to allocate quantitative features from the image of the fuel spray nozzle, and using these features, check whether the point set of drops depicted in the photo is close to the reference image of the spray spot with a reference nozzle with a reference fractional dimension. The convenience of this method of fractal diagnostics is that it does not require the use of special devices for checking and diagnosing injectors, as well as the use of expensive photometric equipment.

  Keywords: fractal diagnostics, quantitative features of the saw cut, point set of drops, reference fractional dimension, special diagnostic devices.
