Air cooling system is carried out to the outer parts of the engine is radiated and driven away by the air stream obtained from the atmosphere. For efficient cooling fins are provided around the cylinder and cylinder head to increases the contact area. Air colling system mainly depends upon the following factors.
- The total area of fin surface
- The velocity and amount of the cooling air
- The temperature of fins and of the cooling air
Let us have a deep insight into the disadvantages provided by the air cooling system.
Disadvantages of air cooling system :
- It can be applied only to small and medium engines.
- Cooling is not uniform.
- In places where ambient temperatures are lower.
- Higher working temperatures compared to water-cooling.
