Purpose Of INTELLIGENT COOLING SYSTEM
The basic principle behind “INTELLIGENT COOLING SYSTEM” is to control the flow rate of coolant by regulating the valve by implementing FUZZY LOGIC.
In conventional process the flow rate is constant over the entire engine jacket. Which induces thermal stresses & reduction in efficiency.
This is a concept and an innovative idea not been implemented yet.
INTRODUCTION
The name “INTELLIGENT COOLING SYSTEM” represents the improved function of cooling systems. We have given this name because in this system the sensor will sense the cylinder temperature as similar as thermostat and will control the opening and closing of water passage in the piston cylinder arrangement. The mass flow rate of water will be controlled by a valve arrangement.
For regulating flow rate, a separate programming can be done. In this programming, the piston will be considered as an object and a relation of “temperature = water” can be used for the above purpose.
CONVENTIONAL COOLING SYSTEM
The following are the two main characteristics desired of an efficient cooling system
1) It should be capable of removing about 30% of heat generated in the combustion chamber while maintaining the optimum temperature of the engine under all operating conditions of the engines.
2) It should remove heat at a faster rate when engine is hot. However, during starting of the engine cooling should be minimum, so that the working parts of the engine reach their operating temperature in a short time.
Effect Of Overheating
Burning of PISTON CROWN
Evaporation of lubricating oil that lubricates the piston and cylinder wall
Sticking of piston rings in the ring grooves
Reduction in volumetric efficiency
CONCLUSION
We have proposed an approach to implement fuzzy logic in an "Intelligent Cooling System". Possible implementation of the system and an approach is discussed along with its possible advantages. The use of such system will solve the problems of technology acceptance in India.
Scope for future work would concentrate on type of sensor's, valve opening mechanisms and different coolants.
