Advanced engine cooling system design to improve engine performance

In this study, smart cooling design and optimization, which is based on a dual loop cooling system, is used to increase the efficiency of the engine and decrease the fuel emission levels with the artificial intelligence approach. Dual circuit cooling system is used to cool down the charged air and condenser for the 1.6 lt turbocharged diesel engine. The main objective is to increase the efficiency of the engine and decrease the fuel emission levels with a smart cooling system design using 1D analysis, experimental tests and neural networks. Water-cooled air charger and water-cooled condenser are placed separately on engine bay. Whereas, similar applications have been used for these modules integrated on the engine itself. Artificial Neural Network approach and graphical optimization is applied in order to optimize the water cooled air charger sizing. Input data is generated by using 1D model within the correlation of experimental test results both on dyno and road conditions. Experimental and 1D analysis data comparison shows that they are very coherent. Results showed that efficiency of the engine is increased, and lower emission values are obtained with a more efficient dual loop cooling system design and optimization based on 1D model, experimental tests and neural network approach.
