To engage or disengage the engine from the transmission.
To prevent the car from stalling
it might not have any hydrolic fluid in the clutch master cylinder to engage the cluth or your clutch might me shot and just won't engage at all meaning you need a new one (was there a smell in the car right before you couldn't use clutch? that might of been the clutch burning up). don't quote me on all that I'm just telling you what you can check.
There are several things that happen when you burn the clutch. The basic thing is that you are not able to engage the gear which means that you will not be able to move the car.
Most likely the clutch is shot. When the clutch plate can't engage with the transmission there will be slippage between the engine and the drive wheels.
An air conditioner clutch will not engage without voltage. If it doesn't engage, the compressor will not turn.
Whatever the car, it has to do with the clutch. If the clutch does not dis-engage the fly wheel, you will be unable to shift or even get it into gear. Check you clutch, pedal, cable, or hydraulic system.
If the clutch won't engage, the clutch disc or pressure plate has probably broke apart. If the clutch won't disengage, the clutch hydraulic fluid reservoir is empty because of a leak in the system.
Is to disengage and engage
have you tried checking the clutch master cylinder? not sure if the same as others ive done, but usually its right behind the clutch peddle.
After you engage a gear and let out the clutch and accelerate the car wont move faster but the RPM's will move up. Also in some rare instances when a clutch disk material separates from the disk its self you wont be able to start the car or even change gears.
A clutch does not go into gear. A clutch engages, Normally if a clutch fails to engage it is because it is worn. with a worn out clutch you are able to start the car in gear without your foot on the clutch and the car wont move. Normally before this happens you will notice what is known as a slipping clutch. A slipping clutch means that the engine is turning faster than it should to keep the car moving while in gear. once this starts to happen it does not take long for the whole show to come to a stand still.
