While I was sitting in flight theory class, the instructor was talking about carb icing for the planes that we fly. See, as the high speed air air passes through the venturi in the carb and picks up the vaporized gas molecules, the temperatures can drastically decrease. When we fly these little airplanes on cold days, we have to use what is called "carb heat". All it is, is a airbox or farings that directs air over the exhause pipes, "which heats up the air" and then forces it into the carb. This melts any ice that was forming inside the venturi of the carb and eventually makes the engine run better. Now that I explained this, why haven't I ever heard of this on snowmobiles? People way up north in the really cold areas, I would think would have problems with carb ice forming. On the brand new airplanes that have electronic fuel injection, there is no longer need for carb heat because since there is no carb for the fuel to be mixed in, the temp. cannot decrease to form ice. This is just another one of my day-dreams that helps me through the 3 hour class, 2 times a week. Let me know what ya'all think on why snowmobiles do not need carb heat?
