it"s just idle condition...the engine will be running

Usually to reverse the direction of rotation in a gearbox etc.
To keep tension on a chain or belt.

No. But if there are two idler gears, one smaller than the other, say a 12 tooth and a 6 tooth. the 12 tooth idler is the idler of the driver gear which has 24 teeth, making the idler gear rotate 2 times for every rotation that the driver gear rotates. Now, if the 12 tooth idler gear is rotating 2 times faster than the driver gear, then the 6 tooth idler gear will rotate 2 times faster than the 12 tooth idler gear. So, the 6 tooth idler gear is rotating 4 times faster than the driver gear. Let's say that the driven gear has 12 teeth. For every rotation of the 6 toothed idler gear, the driven gear rotates halfway.
An idler gear is a gear which connects two other gears so they will turn in the same direction. :)

An idler gear is a gear which connects two other gears so they will turn in the same direction. :)
An Idler Gear is usually used to maintain a stable tension on a belt or chain, OR it is used to redirect the position of the belt or chain. An idler gear transmits no power to or from the belt or chain.
An idler gear supports a belt, routes a belt around obstructions, increases the amount of area a belt contacts a pulley, or adds tension to a belt or chain drive system. In the case of a gear chain, the idler would reverse the motion of the gear it drives.
An "idler" is typically used for tensioning of a belt, as in the timing belt, or a chain.
