LUBRICATION SYSTEM
Need Of Cooling System In Engine
Engine creates up to 5,000 degrees of heat within the combustion chamber. Enough heat to melt the entire engine in less than 30 minutes!.
The cylinders of internal-combustion engines require cooling because of the inability of the engine to convert all of the energy released by combustion into useful work.
Liquid cooling is employed in most gas engines, whether the engines are for use in automobiles or elsewhere.
The liquid is circulated around the cylinders to pick up heat and then through a radiator to dissipate the heat. Usually a thermostat is located in the circulating system to maintain the designed jacket temperature—approximately 88 °C (190 °F).
Main Components Of Cooling System
1.Coolant Pump
2.Thermostat
3.Radiotor
4.Tubings(Pipelines)
Problem In Cooling System
Here engine has some tripping parameters. If any of them fulfill the condition then engine trips automatically.
For example if engine pressure, engine speed , vibration and engine temperature etc. will crosses the normal set value then engine trips.
During our training period we found that engine trips due to high jacket water temperature.
As concern with jacket water temperature , may be any of the component of cooling system works not properly so coolant temperature increases and engine trips.
