Heat Stove Function.

If I understand correctly, it's kinda like a primative EGR valve. But 
it does function in tandem with the Air Inlet Valve.

The heat stove wraps around the exhaust manifold. Any ambiant 
air between the stove and the manifold is warmed by the radiant 
heat of the manifold from the hot exhaust gases inside. A hose 
connects the Heat Stove to the Air Inlet Valve. When the outside 
air temp drops below a certain degree, a bi-metal arm bends to 
move a flap inside to alow the vaccum created by the engine 
intake to suck hot air in from the Heat Stove.

So instead of returning hot exhaust gases into the engine like an 
EGR valve, the setup on the DeLorean simply pumps in fresh air 
heated by the exhaust gases.

As a side note, I removed this entire setup for my car, and have 
gotten a slight increase on performance since due to the lack of 
restrictions on the air intake. But now the exhaust on cold 
mornings is quite potent for a little while longer then it used to 
be.
