Does a Mercedes clk compressor have supercharger?

The Mercedes CLK compressor does not have a supercharger, it has a mechanically driven Roots-type positive-displacement supercharger. A supercharger is a device that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle more oxygen, letting the engine burn more fuel and deliver more power. In contrast, a turbocharger uses the exhaust gases of a reciprocating engine to drive a turbine, which compresses the intake air.
