Abstract
The study of gas-dynamic processes in gas-air systems of engines in order to improve the processes of gas exchange, mixture formation and combustion is an urgent task. The results of experimental studies of gas-dynamic processes in the intake system of an engine with turbo-compressor are presented in the article. A brief description of the setup and methods of experiments is presented. A spectral analysis of functions was chosen as a tool for monitoring gas-dynamic phenomena in different systems. A comparative analysis of the amplitude spectra of the pulsations of the velocity and pressure of the flows in the intake system of the engine with and without a turbo-compressor is presented in the article. The installation of a turbo-compressor leads to a significant change in the structure of gas flows in the intake system. A method for stabilizing the pulsating flow in the intake system by installing a leveling grid in the output channel of the compressor is proposed. It has been established that the presence of a leveling grid in the intake system of an engine with turbo-compressor leads to a decrease in the low-frequency amplitudes of the velocity pulsations and the pressure of the flow by up to 30%. © Published under licence by IOP Publishing Ltd.
