Pressurized Water Cooling System In Automobile

The boiling point of water increases when the water is placed under pressure.

Pressurized water cooling system in automobile.

It is generally a limitation of most cooling systems that the cooling fluid not be allowed to boil as the need to handle gas in the flow greatly complicates design. Under pressure the boiling point of the coolant is raised considerably. When the fluid in the cooling system heats up it expands causing the pressure to build up. Pressurized cooling systems radiator caps for pressurized automotive cooling systems.

Vehicles these days have a recovery tank to store that discharged coolant. When the cooling system s pressure exceeds the safety limit the cap s safety valve opens to discharge the extra coolant. The cooling system in your vehicle is designed to keep the engine at a consistent temperature. The same way a pressure cooker increases the boiling temperature of water.

This technology has been around in f 1 and indy cars for many years. If you have had any parts replaced on your cars cooling system radiator waterpump new hoses ect then there is a chance that your cooling system has air trapped in it and this could make your cars cooling system operate poorly or in worst cases minic the symptoms of a cracked head. However too much pressure will cause hoses and other parts to burst so a system is needed to relieve pressure if it exceeds a certain point. In order to prevent the coolant from boiling the cooling system is designed to be pressurized.

The cooling system consists of several main components that each perform a different task. It keeps the engine from running too hot or too cold once it is warmed up. The cap is actually a pressure release valve and on cars it is usually set to 15 psi. A radiator or cooling system pressure test is useful when finding a radiator leak or a blown head gasket.

Of the two valves one prevents the creation of a vacuum the other limits the pressure. It s more efficient and more failsafe than.
