The main part of the fuel delivery system in modern diesels is Common Rail system with this or that fiatures. The major unit of any Common Rail system, that provides fuel delivery processes is injector with elecrohydraulic control. Injector is a comlex hydraulic system and consist of variable volume cavities, channels, slides, valves and jets interacted among themselves. Methodology offered in the article allows to make a preselection of the main constraction parameters in the control chamber during new injector designing. This preselection took place according to workability and performance of the injector.

Key words: Common Rail, injector with elecrohydraulic control, control chamber.
