1. In Air cooled engines there are two types. One is pressure cooling second is natural incoming force system
2. In water cooling system also there are 2. One is thermosyphon second is forced feed.
3.In air cooled system fins are provided around the cylinder and head to transmit heat
4. In water cooling system a radiator is used to tranfer the heat
5. Minimum temperature of the water can be controlled in water cooled system by using a thermostat
6. Minimum temp can not be controlled in air cool system
7. Engine oil temperature raises to high in air cooled system and requires frequent drainin
8/ Engine oil temperature is under control in water cooled system
9.More space required for water cooled engines
10. Less space compared to water cooled engine requires for air cooled engines
11. Heavy oil leakages are found in air cooled engines
12. Air cooled engines are noisy then water cooled engines
13.Anti freeze requires to be added in water if worked in coled icee areas in water cooled engines
etc. etc.

Air cooling is cheaper because the engine is constructed more lightly. This system is often seen with a forced cooling (fan), because a lot of air is needed to cool down the engine. The generating set is a stationary machine that cannot receive direct air cooling like a motorbike for example.

 


 


With water or liquid cooling, the liquid is pumped around the engine. The liquid eventually arrives in a unit with a large cooling area (the radiator) so it can be cooled down. This cycle is repeated without interruption.
 
The specific heat of water is higher than the specific heat of air. That is why liquid cooling is mostly more effective than air cooling. A disadvantage of water cooling is that a leakage in the liquid tubes can occur and cause a short circuit in the alternator or in the electric part of the generating set. Another disadvantage of water-cooled generating sets is that we are dealing with large, heavy and complex installations. Air-cooled sets mostly only have a fan (ventilator). One of the advantages of water-cooled generating sets is that they are quieter because liquid serves as acoustic insulation.
