Numbered style of referencing and numbers of authors

Hi everybody,

When my reference has 4 or more authors, only the 1st one is written in the Bibliography (example : Author 1 et al.,)

When my reference has 3 or less authors, all the authors are wrtitten in the Bibliography (example; Author 1, Author 2 and Author 3).

I would like to have “Author 1 et al.” when the reference has 2 authors or more but I can’t figure out how to do. 

I am using the numbered style of referencing.

Thanks for your help.

Laurent.
