why is water circulated in the engines of a car
Answers
A car engine produces a lot of heat when it is running, and must be cooled continuously to avoid engine damage.
Generally this is done by circulating coolant liquid usually water mixed with an antifreeze solution through special cooling passages. Some engines are cooled by air flowing over finned cylinder casings.
Answer:
Explanation:
As the coolant flows through these passages, heat is transferred from the engine components to the coolant. ... Once the fluid is cooled, it returns to the engine to absorb more heat. The water pump has the job of keeping the fluid circulating through the system when the engine is running.
Unless they're air cooled (old VW and Porsche motors) they need a liquid coolant of some kind. In a pinch this can be just water but it's better if it's both antifreeze and water.
They need the coolant to keep the engine operating within temperature spec. If it gets too hot it can, among many other things, burn off oil and seize. Assuming the thermostat is open the coolant cycles through the engine block and then the radiator (which is just a large heat exchanges) and then back to the engine block.
