Evaluación del uso de nanopartículas de titanio y silicio para el mejoramiento del sistema de refrigeración de un vehículo.

Abstract

This project aimed to analyze the behavior of an Otto cycle engine coolants using nanoparticles of titanium dioxide and silicon dioxide in a vehicle Chevrolet Aveo electronic injection engine and 1.6l. The project begins with the definitions, applications, and thermal properties of nanoparticles and nanofluids, the basic principles of heat transfer, operation, parts and operation cycles of an internal combustion engine. Then the selection criteria, methods, procedures, parameters and analysis used for the preparation and characterization of nanoparticles and nanofluids are indicated. The procedure and equipment used for testing torque and power dynamics ASM emissions and fuel consumption established, then the results are analyzed and the mechanical behavior for each coolant was compared. Finally, it was established that the use of coolants NPs titanium dioxide and silicon dioxide improves engine performance reducing emissions, which are the result of a combustion chamber at a lower temperature, decreasing consumption gas.
