The Comprex charger is back

The Comprex (TM) supercharger, like the turbocharger, is a Swiss invention. The Comprex uses pressure waves in direct contact of the exhaust gas with fresh air for supercharging, while a turbocharger couples two flow machines (a turbine and a compressor). Now a brand new design called “Comprex 2.0” showed many advantages in combination with a natural gas engine.
