Does my E320 have a jet engine?

Can anyone tell me why when I start my 1996 E320 it sounds like a jet engine is starting up and then after a minute the sound stops? It has always sounded like that but I was just wondering what makes the sound. Is there something like a small turbo fan that is trying to heat up the air by higher compression when the engine is cold?

The Noise is The Smog (AIR) Pump that kicks in on the start up..
