Answer 2

In scooters, fins are provided over the engine cylinder for better cooling. (Option 4)

• The engine cylinder is exposed to a lot of temperature variations.
• The heat could be reduced by increasing the surface area but that is not feasible in a scooter.
• The fins provided dissipate the heat generated which increases the life of the engine.
• However, it starts working only when the engine has generated enough heat and not when it is just warming up.
