The pressure wave supercharger (PWS) offers a promising alternative to turbochargers and mechanical compressors. Originally developed in the 1980s, this technology is gaining increasing importance in response to new emission regulations and downsizing requirements for gasoline engines a fascinating boosting device!

​

The PWS provides extremely rapid response and avoids the typical turbo lag. Thanks to the absence of the so-called pump limit at low engine throughputs, very high boost pressures can be achieved, enabling both downsizing and downspeeding simultaneously. This results in impressive efficiencies exceeding 90%, otherwise only found with large turbochargers.

​

Moreover, the pressure wave supercharger positively affects cold start emissions since the catalyst can be placed directly in front of the charger. This significantly shortens the warm-up phase, which in turn reduces engine fuel consumption and optimizes performance. The PWS also demonstrates strengths in altitude boosting.

​

Antrova has further developed the Comprex™ charger to meet the challenges of operational reliability and stringent emission standards. The Comprex™ delivers excellent performance without the need for additional measures such as e-boosters or complex charger combinations.

​

From small automotive applications to large engines with up to 5 MW output, the pressure wave supercharger is versatile.
