Scavenge Air Waste Gate
1. General
Some engine versions have a scavenge air waste gate, which protects the engine
from scavenge air pressure that is too high in arctic conditions (when the outside air
temperature is below the related value). The waste gate valve operates as a safety
valve, i.e. the overpressure is blown off into the engine room.
The waste gate valve (2, Fig. 1) is attached to the scavenge air receiver.
