Carb ice in car vs. aircraft

[Minuteman]

Cars have a coolant bypass that circulates warm coolant around the carb/ tbs to warm them, like full time carb heat

All fuel injected tb's in cars have the coolant heat.

:yeahthat:

Except I can say the older Buick 3300 V6 did not have a coolant loop in the throttle body, as I almost got stuck out in the middle of BFE Iowa once due to ice buildup. Cruising along the highway, the car slowly lost power, more, and more. Not a fun feeling when it's that cold.

I seem to end up with a new econo airport car every 2-3 yrs, and they all have it... Be interested to see if the M3 has it when it arrives late this month

seems like lots of toyota's, honda's and mazda's ( also by default, fords) run it

Pretty much all the German cars don't heat their throttle bodies.

I was talking to my good friend contactground.9 a few minutes ago and he asked me something I'd never thought about...why do old cars with carbs never get carb icing, yet it happens on a regular basis with aircraft engines?

Hey That's MEE!!

Its amazing the things you think of when you are driving 16 hours by yourself.

Prob. not.. When i was last working as a tech (longtime ago) it was actually considered part of emission controls. I guess they claimed that condensation built up in the throttle body would mix with bits of oil and such from the breathers, and the pass into the combustion chambers, increasing emissions. Heating the bodies prevents that condensation from forming after shutdown, eliminating the problem.

I'm guessing that they don't "really" need it though
