Electromechanical grill block gizmo

[Piwoslaw]

Wow! Now that's something Slow, compared to the 'instant' open of my grille block (I should post a vid), but the 30-40 seconds it takes is enough.

Nice work, augustinionut, and welcome to EcoModder

...yes, "Welcome," and how much current does that motor draw while operating?

[augustinionut]

Really, i don't know But because of that long time to open-close, i will use a choke cable this winter to operate-it, untill ill find a rapid servo.

...one nice aspect of the motor-driven shutter is that it can be stopped & started at any time to achieve "air flow-control" so the radiator doesn't over heat.

[augustinionut]

I used only to speed warmup of the motor, for fuel economy and for driving fast, faster in winter mornings
I need your help: there is a large bimetal blade capable to pull my grillblock? Sticked to exhaust cover plate?
EDIT This will work?

Look what i found.... silich.ru/zhal.html

[augustinionut]

Did someone tried to use exhaust heat to warm the car (the engine)?


Until now:

Maybe someone could use this controller for a grill-block-gizmo:
Autospeed article: $25 Temperature Controller and Display!

I agree that best place for temperature measurement is radiator return line. Example if normally radiator drops temperature from 90 C to 70 C then you set threshold to around:
if temp higher than 75 then open grill, shut grill if lower than 70

Nice!
I wonder how it will work at speed, when air pressure will be pushing it?
