The system control test bench, fuel equipment of diesel engines. The use of asynchronous motor together with the Converter of frequency allows to create an effective budget system of adjustable electric drive for maintenance of necessary speed asynchronous electric drive depending on pressure. The proposed management system provides the fuel supply pressure-stable, leading to a significant decrease in hydraulic loads of fuel and diesel equipment. The use of frequency Converter reduces the dynamic load on the engine and optimize operating currents, which creates conditions to reduce energy consumption and increase the service life of machinery.

The solution of the problem of optimizing the functions of several re-variables in the form of a second-order polynomial in CAD in the absence of reference points. The analytical dependence and algorithm which allows to find the optimal parameters of the systems and processes in CAD, and can be used in the practice of design work.
