Acm style bibliography is shortening 3rd author

Question

I have the following entry in my bibliography :

@article{szymanski,
author={Zbigniew Szymański, Stanisław Jankowski, Jan Szczyrek},
title="Reconstruction of environment model by using radar vector field histograms",
journal="Photonics Applications in Astronomy, Communications, Industry, and High-Energy Physics Experiments",
volume= "8454",
issue = "4",
pages= "1-8",
year="2012"
}

When I put a reference to this article I get in the references section this :

How do I prevent the shortening of 3rd author ?

( I can provide what am I using - whether it is Bibtex or Biblatex or anything - but how can I check it?)

Your authors:

Zbigniew Szymański, Stanisław Jankowski, Jan Szczyrek
