The Auto Cooling System

2021-08-20

Most of the energy in gasoline (about 70%) is converted into heat, and dissipating this heat is the task of the car's cooling system. In fact, a car driving on a highway, the heat lost by its cooling system is enough to heat two ordinary houses! If the engine becomes cold, it will accelerate the wear of components, thereby reducing the efficiency of the engine and emitting more pollutants.

Therefore, another important function of the cooling system is to warm up the engine as quickly as possible and keep it at a constant temperature. The fuel burns continuously in the car engine. Most of the heat generated in the combustion process is discharged from the exhaust system, but some of the heat remains in the engine, causing it to heat up. When the temperature of the coolant is about 93°C, the engine reaches its best operating condition. At this temperature: the temperature of the combustion chamber is sufficient to completely evaporate the fuel, so it can better burn the fuel and reduce gas emissions. If the lubricating oil used to lubricate the engine is thinner and has a lower viscosity, the engine parts can operate more flexibly, and the energy consumed by the engine in the process of rotating around its own parts will also be reduced, and the metal parts will be less prone to wear.
