The most important element that contributes better atomization of air-fuel mixture, as well as better performing of combustion processes, is an introduction of direct injection of fuel under high pressure into the working chamber of the diesel engine. Beside reduction of pollutants emissions, injection under high pressure makes possible a lower fuel consumption and lower external noise of the diesel engine. A significant attention has been dedicating to design of injection law. A method of calculation of the optimal injection law, as well as an influence of elements of fuel supply systems on the injection law, is presented in the paper.
