Cooling Systems Of Internal Combustion Engines And Coolant Selection: a Critical Component

Abstract

Internal Combustion (IC) engines generate a significant amount of heat during operation, which can lead to engine damage and decreased performance. A well-designed cooling system is essential to regulate engine temperature and prevent overheating. This paper discusses the components and working principle of a typical IC engine cooling system, as well as the selection criteria for coolants. The physical, chemical, and mechanical properties of different types of coolants, including water, ethylene glycol, and propylene glycol, are compared and discussed.
