I think it's the wheel that connects the starter to the engine when you start, a solanoid pushes it into the engine, then disengages it once you let go of the key.

it makes the shifts faster... like on a manual red lining, when your in 1st n switching to 2, your rpms might fall down to like 3, but with a flywheel it might fall to just 4, giving you more power. i'm not 100% sure about this so dont quote me, and the examples i give probably arent accurate but you get the idea...

A flywheel keeps the engine running at a consistant speed (i.e. from stalling and from running too irratically). The flywheel connected to the engine and is always engaged or turning with the engine. If you get a lighter wheel, your engine will rotate faster (quicker acceleration, etc.) but the caveat is that if the wheel is improperly lightened it will mess up your engine (not exactly sure as to how yet but it will). Plus, installing one is major $$$ (more than the actual wheel I think)

The flywheel is bolted to the crankshaft of your engine. Then the clutch is bolted to it. But if your car is auto it has a flexplate which is bolted the same way to the crank, but instead of the clutch, the torque converter is bolted to it. If you get a lighter one of either of these, it will decrease your reciprocating weight and your car will rev faster. I hope this clarifies things[IMG]i/expressions/face-icon-small-smile.gif[/IMG]

thanks. does anyone know if the whole engine must be removed from the car to install the flywheel? cuz its connected to the tranny or something..?

Hey baller, you don't need a Flywheel...you car's tranny is automatic...a flywheel is used on manual transaxle engines...becuase it's connected to the clutch system...autos have a torque converter[IMG]i/expressions/face-icon-small-wink.gif[/IMG]

and you don't have to remove the engine, but you have to remove the transaxle to reach the Flywheel....it's located between the engine and the transaxle

What the flywheel actualy does is give the clutch disk something to press against ingaging the clutch which in turn makes the gears turn, which makes the wheel turn.

Actually is used for various things, including the things you said


<< connects the starter to the engine when you start, >>





<< A flywheel keeps the engine running at a consistant speed (i.e. from stalling and from running too irratically). The flywheel connected to the engine and is always engaged or turning with the engine. If you get a lighter wheel, your engine will rotate faster (quicker acceleration, etc.) >>



But a lightweight flywheel will make your car go slower when going up hill, for the same inertia reasons...less inertia

Alright, I have read this thread, and I can tell you that you guys are close, but not right on. I am actually a hummer mechanic, and six months away from being ASE certified on regular standard style cars. A flywheel IS connected to your crankshaft. Recall that 99% of cars on the road have four stroke engines. Four stroke cycle includes, the intake stroke (pistons moving downward with intake valves open creating a vacuum sucking in air and fuel), the compression stroke (both intake and exhaust valves closed, piston moving upward in the cylinder to compress the air and fuel mixture), the power stroke (the ignition of the air and fuel by the spark plug forcing the piston back downward), and the exhaust stroke (the piston moving back upward to push the burned mixture out of the exhaust port).

Now, that we have that clarified, basically a flywheel is connected to your crankshaft which is connected to your pistons through the piston arms. The flywheel is offset on the crankshaft so that it can keep it spinning throughout the fourstroke cycle. The power stroke is what starts the cycle, but it takes the flywheel to keep it turning throughout. Getting a lighter one would help performance for obvious reasons. But this is essentially the purpose of a flywheel.

Did this help you to understand flywheels at all?

All right answers, the flywheel is connected to the crank, but it acts to store kinetic energy as potential energy. This stored energy will keep the rpms running smoothly. This means sudden loads will not have an immediate effect on the engine. Whether you are running uphill or down the rpms will not rise or fall suddenly. A heaver flywheel will store more energy, but is harder to spin up to speed, a lighter flywheel will spin up more quickly, but you loose the smoothing function that it provides. If you race, a lighter flywheel will allow faster reving, but a daily commuter should stay stock.[IMG]i/expressions/beer_yum.gif[/IMG][IMG]i/expressions/beer_yum.gif[/IMG]
