The cooling medium is not just water, but a mixture of water and coolant additive. The Necessity of having a good Engine Cooling System An Engine Cooling System is a system that controls the engine temperature, is known as a cooling system. The system has an expansion tank which is only around half filled. This constitutes a closed cooling system. The cooling circuit is under pressures between 1.0 bar and 1.5 bar. The engine's operating temperature is not only important with regard to performance and fuel consumption, but also for low emission of pollutants.Įngine cooling uses the fact that pressurized water does not boil at a temperature of 100 ☌, but only between 115☌ and 130☌. That control system has remained the basis of all systems to this day. The thermostat only opens the connection to the radiator once the desired operating temperature is reached. The thermostat was a decisive improvement to engine cooling and enabled short-circuit coolant circulation While the desired engine operation temperature is not reached, the water does not run through the radiator, but by-passes it and runs into the engine. We are referring to a thermostat-controlled cooling system with the following functions: In 1922, it is described as follows: "The purpose of these devices is quick engine heating and prevention of cooling down of the engine." The water circulation through the radiator is regulated depending on the coolant temperature. In the further development of engines, cooling water regulators (i.e. Low engine temperature during the cold season.Later, a water pump accelerated the water circulation. Cooling was supported by the fan, but regulation was not possible. The water is circulating while the engine is running. It then sinks down and is returned to the engine. The heated, lighter water rises into the upper part of the radiator through a manifold and is cooled by the air flow. The first kind of cooling with water was thermosyphon cooling. Therefore, the engine is cooled down to operating temperature. The temperatures generated by the burning fuel (up to 2,000 ☌) are detrimental to engine operation.
