The Uses of a PCV Valve

Of all the motor systems in an automobile, the engine is the most crucial player for the vehicle to operate. The engine has to generate energy that is converted into motion by the other components of the vehicle. For this motor-driven system to function well, it needs assistance from other parts. Like a knock sensor, which monitors the efficient generation of horsepower, the PCV valve or Positive Crankcase Ventilation valve also looks after the engine.

The primary part of the PCV assembly, this component is a tube-shaped regulator that gets rid of the unwanted gases inside the engine block. Once the engine is triggered to life, there are some gases that seep out from the cylinder and go directly to the tough crankcase, which is the largest area in this system. With the PCV valve intact, however, such incidents can be prevented. This valve removes these gases from the crankcase and brings them to the intake manifolds. Along these passageways, the gases are recycled and brought back to the crankcase as fresh air.

With the PCV valve, the crankcase does not suffer from the unwanted gases that can lead to damages such as the formation of rust and the congestion of manifolds. If these gases, which include Carbon dioxide and hydrocarbon, stay long enough inside the crankcase without being recycled, the biggest chunk in the engine system can get significantly damaged. The aforementioned effects also contribute much as to why an engine overheats or produces a great amount of noxious emission.

Clearly, the PCV valve is not just a special add-on part but it is a staple in any automobile. With this intact under the hood, the engine system gets to function well and avoids any problems. The engine remains efficient and produces the energy needed for the whole vehicle’s operation.
