In another post Rich mentioned that he disconnected his AAR & CS Valve saying they weren't necessary where lives, which I'm pretty sure is lower Slobovia. So I thought I would disconnect mine here in SoCal. Guess what? My idle stabilized. Impossible! It tested fine when I first resurrected this engine but was now sticking open. So I took the opportunity to take a few shots of this AAR valve in action. I will try to post 6 pic's so it will probably take 2 posts.
Ambient temp = 71F Humidity = 100% rain First pic shows the valve temp after a 10 min quench in the freezer. Temp's shown are the skin temps and are surely different than those at the core or bi-metal strip which controls the degree of movement within the valve.  This shot shows the valve opening at this temp. It appears to be 1/2 open. Will it open further? I don't know but at this setting I could blow thru the valve without any noticeable back pressure.  After energizing the AAR for 5 min's the surface temp was 97.1F as shown.  |
