Unlike the class 2 system wet vapour is introduced into the cooling jacket.
Evaporative cooling system in ic engine.
On the basis of medium in general use for cooling i c.
A condenser into which the gaseous coolant from.
All the i c engine require a cooling system because combustion of fuel takes place inside the engine itself.
Engine types of cooling system are 1 liquid or indirect cooling system.
Disadvantages of evaporative cooling system.
Forced circulation cooling system this system is used in a large number of vehicles like cars buses trucks and other heavy vehicles.
As steam is much less.
Evaporative cooling system in this system the engine will be cooled because of the evaporation of the water in the cylinders into steams.
The necessity of cooling system in engine.
Means defining in the engine a coolant jacket into which coolant is introduced in liquid state through an inlet port formed in the engine and from which the coolant is discharged in gaseous state through an outlet port formed in the engine.
The downside to the evaporative cooling system is the area of the condensers required to cool the steam back below the boiling point.
This patent describes an evaporative cooling system of an internal combustion engine comprising.
This class is also based on a fully evaporative system concept in which engine cooling is achieved only by changing the dryness fraction of vapour passing through the cooling jacket.
It is used for cooling of many types of industrial engines.
The heat transfer to the vapour increases the dryness fraction to just below 100.
2 air or direct cooling system.
Such a system can be effective even with much smaller amounts of water.
In effect the evaporative version is operating between 80 c and 560 c a 480 c effective temperature difference.
Within the engine the fluid likely water reaches the boiling point but is not allowed to fully vaporize as the circulating engine coolant is flowing rapidly and at a pressure sufficient to minimize vapor production.
A liquid cooling system for an internal combustion engine includes a conventional radiator and circulating system and pressure cap the latter having pressure and vacuum relief valve components for limiting the maximum operating pressure of the system and for limiting negative pressures to avoid damage during cooling after engine shutdown.
Evaporative cooling systems may be applied in two ways within the engine itself or in an external circuit.
V compact engine design with minimum frontal area as possible.
Iv as far as design of cooling system is concerned the engine size does not involve any serious problem.
I it is dependent on supply of water.
