Difference Between Governor and Flywheel - Get Your Answer Now!

[R Power]

Hi guys
What is the difference between flywheel and governor? Well, I know that flywheel is a wheel which stores and releases energy and avoid fluctutations in speed and governor controls fuels supply when speed is in access or very less through centrifugal action.
But what i am confused is what's diff between two? Both tend to stabilize speed. So is the diff only in the way of working or what?

A governor changes its mechanical and/or electrical configuration in response to speed variations. Those changes are used to control the input.
I suppose that such mechanisms could be built into a flywheel, but I've never heard of it being done. Normally, a flywheel is a fairly rigid structure.

Is there any use of governor in ic engines of cars?

Tractors have governors so a set RPM may be maintained for plowing, etc..
the closest to a governor on automobiles is cruise control where a specific MPH is locked in and the engine varies RPM to maintain the speed regardless of hills , terrain

Don't forget rev limiters on high-performance engines as well. These are usually built into the tach. Most just shut the engine down, but some selectively dampen spark activity to maintain rpm's at the redline. Also, some commercial vehicles such as Greyhound buses have driving speed limiters.

Actually, the first governor used something like a flywheel. The invention was the http://en.wikipedia.org/wiki/Centrifugal_governor" by James Watt.

Don't confuse this, a flywheel is NOT a governor. A flywheel may well be a component in a governor as bluelava0207 linked to, but they're not the same. Danger's responses are bang on; in a normal automotive application any governor operates as engine overspeed protection.

Flywheels are used for short-term energy storage, like on the one-cylinder hit-and-miss farm engine, which had to coast for 720 degrees (somethimes more) between spark ignition. See thumbnail. For four-clinder automobile engines, a flywheel makes the idle RPM smoother.

There is a governor in many cars, although not in the engine, but in the automatic transmission of non-computerized transmissions. It regulates oil pressure to change gears. Look under transmission components governor:
