Scavenging is an important gas exchanging process in a 2 Stroke Marine Diesel Engine. It is done with the help of Turbocharger, Charge air cooler, Scavenge manifold, Scavenge ports, Exhaust valve etc.
During downward stroke of piston, when piston goes below scavenge ports, fresh charged air is supplied into cylinder liner and exhaust gases escapes via exhaust valve. During upward stroke of piston, this fresh charged air is compressed to get auto-ignition temperature of the engine. This whole process is called Scavenging.
Here you can see the various fittings in scavenge manifold (scavenge space) like flaps, relief valve, temperature sensor, door etc.

Dirty scavenge space leads to scavenge fire which is dangerous to engine as well as personnel on board. So, we have to keep clean scavenge space at regular basis.
