Defining the parameters of the optional electrically controlled supercharger

The article proposes a method for determining the technical characteristics of an additional controlled electric supercharger as the first stage of pressurization of the D-260.2 engine. The article discusses the main direction in the development of diesel engines, in particular the engines of automotive and tractor equipment. The use of the first controlled stage with an electric drive of the boost pressure is proposed, which allows controlling the boost pressure over almost the entire external speed characteristic of the D-260 engine by limiting the maximum combustion pressure at the pressure level at the nominal mode in the basic configuration. The directions of research in the field of turbocharger are determined. The purpose of this work was to improve the energy efficiency of the D-260.2 engine. Calculations were carried out, including a set of mathematical and algorithmic models, as a result of which the possibility of using a compressor electric drive in a two-stage engine boost system was confirmed, which allows obtaining a controlled boost. An "Installation for the study of the characteristics of an additional supercharging with an electric drive" was created to determine the required parameters of the "Additional Controlled Electric Supercharger" (ACES). Based on the obtained flow characteristic, a controlled electric blower was determined - the required power, flow rate and air flow rate. The results of the work showed the possibility of determining the parameters of additional boost with an electric drive by the proposed method.
