The COMPREX^® pressure wave supercharger in passenger car applications
by A. Mayer, H. Kirchofer
International Journal of Vehicle Design (IJVD), Vol. 6, No. 1, 1985

Abstract: The pressure wave machine COMPREX^® has proven to be a very effective supercharging device for diesel vehicle engines. A supercharger family which with six types covers the entire passenger vehicle swept volume range has been released for manufacture. The design and the charger map are presented. Using the example of a medium type CX 85 for the supercharging of a 1.6 litre IDI engine, the design method is described, and the engine map is shown with and without charge air cooling. Road performance calculations relating to the test vehicle VW Passat are compared to measurements in drive cycle and in city driving and show possibilities for further optimisation, whereby in particular fuel economy is improved.
