Comprex® Pressure-Wave Supercharging for Automotive Diesels-State-of-the-Art 840132

THE COMPREX PRESSURE WAVE SUPERCHARGER (PWS), developed for passenger car diesel engines, is now in production. Those of its properties which influence road performance, fuel consumption, and emission behavior of the PWS charged engine are described on the basis of the maps of the production models. The design for high volume production is presented and substantiated by test results.
6 types are available, covering an engine range from one to three litr swept volume with and without charge air cooling and optional waste gate. Instant response and high efficiency allow downsizing and downspeeding and lead to improved fuel economy, low emission and low noise level.
