Sistema de arrefecimento

Abstract

The combustion process a large temperature difference between the gases and the chamber walls, as well as promoting the transfer of the heat generated to the walls of the the cylinder and, consequently, the head. The large onboard engines need to operated at an ideal temperature, because If the temperature is too low, the parts Will be retracted, the gaps Will be larger and this Will impair the performance of the engine as the engine as well as the life of your parts. IF the temperature is far above the recommended temperature, the parto of Will be dilated, which considerably increases the friction of the moving parts, quickly wearing these parts. Therefore, the cooling system must keep the engine components at médium temperature compatible with the characteristics of the materials. It also ensures that the parts do not wear out excessively. If this heat is not removed, the walls of the cylinder,the head and the piston head Will tend to reach temperatures equal to the temperature of the cycle, ie between 600° C and 800°C. To this and,the cooling sytema is constituted by a set of electromechanical and hydraulic devices whose function is to control the temperature of the MCI.
