What does an insurance underwriter do
The PCV valve is a control device which sends partially burned gases that come from the engine's crankcase to the combustion chamber. Its name, PCV means Positive Crankcase Ventilation and is one of the oldest and most used emission control devices. Although its name might sound very complicated, it is a very simple device and its function can be easily understood.
Due to its tasks, the PCV valve is not only very useful but also implies important benefits. It completely eliminates crankcase emissions efficiently, avoiding that it becomes an air pollution factor. Besides, it also keeps the system free of moisture due to the constant air circulation that it implies.
Besides, the PCV valve also helps keeping the oil and the engine in proper shape extending their life as well. Also, its mechanism is very important for preventing the appearance of engine corrosion as well as it helps improving fuel economy. This way, the PCV valve is very important for different aspects and helps car owners maintaining their car’s engines in shape as well
as providing them with a good administration of the fuel economy
The PCV valve routes crankcase partially burned gases back to the engine. Once these gases go back to the engine, they are re-burned, allowing this way a better use and administration of fuel. The cylinders are an important part in the process since they are who re-burn the gases rerouted from the PVC valve and have a central role in it.
Crankcase emissions can be a great source of air pollution, and therefore the PCV valve is very useful and important not only for the car functioning but also for the environment and health as well. Besides, this valve requires little maintenance and must be replaced at about 40.000 miles. This way, the PCV valve is an easy to maintain piece which implies an important amount of benefits that affect not only the car and its owner but also those who surround him and the environment in general due to the way in which it prevents gases from becoming air pollution factors.Source: www.autorized.com
