Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
- Motorcycle uses air cooling for the sake of reducing weight and complexity.
- An air cooled engine is simpler to design then the water cooled engine because the heat is transferred from the cylinder and head directly to the air.
- There is no need for water jackets, water pumps and radiator in air cooled system.
- Air cooled system uses many fin on the cylinder and head for effective heat transfer that occurs between two medium.
Examples of Air Cooled and Water Cooled system:
- Air Cooled System: General aviation aircraft, Lawn motors, Generators, pump sets and Motorcycles.
- Water Cooled System: Internal combustion engine of heavy vehicle, Personal computer to lower the temperature of CPUs.
Additional Information
Difference between Air cooled and Water Cooled System:
| S.No. | Air Cooled System | Water Cooled System |
|---|---|---|
| 1 | Initial maintenance cost is low due to simple construction | Cost is high due to complicated construction |
| 2 | No handling problem with air | Difficult to handle |
| 3 | No problem in disposing of used air | There is a problem of disposing of used water unless a recirculation system is provided |
| 4 | The fouling effect is low since no corrosion | Fouling effects are high due to corrosion inside tubes |
| 5 | Low heat transfer capacity due to low thermal conductivity of air | They have high heat transfer due to the high thermal conductivity of water |
| 6 | Used for low capacity | Used for large capacity |
