RESEARCH ON SEQUENTIAL SPEED DRIVING OF THE PRESSURE WAVE COMPRESSORS

Pressure wave compressor is one of the efficient compressors that can supercharge internal combustion engines. In this compressor, the intake air interacts directly with the exhaust gases in the rotor channels. Thus, the intake air is directly compressed by the exhaust gases, the role of the rotor is that of distribution of the exhaust gas and of the intake air. For a certain type of compressor, the value of the supercharging pressure varies with the value of exhaust gas pressure and with the driving speed of the compressor. Currently, the pressure wave compressor is driven by the crankshaft. However, this solution limits the efficiency of the compressor because the driving speed depends only on the speed of the engine and not on its load. In this context, this paper highlights another driving solution that streamlines the pressure wave compressor, without particularly increasing the cost of the process of supercharging.
