Abstract
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.
