Cooling system

Cooling system — intended for warming up the engine, maintaining the optimal engine temperature (85-95 C*)

Methods of cooling

Two methods of cooling are used in engines:

• liquid (aqueous);
• aerial.

In the first case, the heat from the walls of the cylinders is transferred by the liquid, and in the second - directly into the environment (air).

The cooling system, in addition to the main function of cooling the engine, performs a number of other functions, which include:

• air heating in the heating, ventilation and air conditioning system;
• oil cooling in the lubrication system;
• cooling exhaust gases in exhaust gas recirculation system;
• air cooling in turbocharging system;
• cooling working fluid in automatic gearbox.
