What Are Cooling Systems In Automobiles?

“A cooling system is designed to take excess heat away from an engine, thereby allowing it to function at the normal operating temperature.”

The combustion of fuels is a highly exothermic reaction, meaning that a large amount of heat energy is released when fuels are burnt. For instance, a petrol fire can be as hot as 1500 degrees, and can release 45 mega-joules of energy per kg of petrol. This is enough to melt aluminium and cast iron, both of which are popular materials in the production of car engines. Even so, we can effortlessly cruise down the motorway in the same car for years on end without the engine escaping from beneath the hood as a hot smoldering mess. Let’s explore what makes this possible!
