The Comprex is the first pressure wave machine to reach series maturity. The direct contact between the media exhaust gas and combustion air permits a transfer of energy at high efficiency. Because of its basic characteristics, the pressure wave machine is especially well suited for the supercharging of passenger car diesel engines. It exhibits a spontaneous response and achieves high supercharging rates over a wide operation range, thereby contributing to an improvement in fuel economy. For the purpose of reducing emissions, it offers a simple means of providing EGR, thermal conditioning of the charge air, catalytic aftertreatment of the exhaust gas in the cell wheel and a compact particulate trap arrangement.
