Characteristics and Matching of the Pressure Wave Supercharger ComprexSr to a Passenger Car Engine 845015

The Comprex pressure-wave machine is well qualified for supercharging automotive Diesel engines, demonstrating as it does, improvements in power output, fuel consumption and emissions. The special form of the charging characteristics is established from theoretical considerations of the pressure wave compression process.Data from the currently available production machines show, with the aid of supercharging parameters, such a pressure ratio, density ratio and adiabatic compression efficiency, the operating limits of the machine with respect to cell filling and pressure-wave tuning.A computer program, interpolating from measured data and using a simplified model of the engine, allows optimisation of an installation considering Comprex type, shaft drive ratio, charge air cooling and control system functions.The correlation of the program with measured values is adequate for the purpose of engine-to-Comprex matching.
