About PCV valve
This attaches to the engine crankcase, where the crankcase is mounted and further to the intake manifold, usually referred to as the positive crankcase ventilation valve or the PCV valve alongside the hose. This allows the lower half of the engine to release gases and pressure at the time the engine works. This control system brings partially burned gases into the chamber for combustion. It is one of the oldest and most commonly used pollution control systems.
What is the purpose of PCV valve?
The PCV valve is an essential mechanism for preventing corrosion in the engine. It eliminates the pollutants from the crankcase and leaves the machine moisture free. It prevents the toxic gases from remaining in the engine block to be elaborated. There is a vacuum hose that connects both of the intake manifold and the PCV valve.
How PCV valve works?
It is clear that the PCV valve performs the critical function of avoiding the entry of the poisonous gases into the engine block. As soon as the exhaust gases reach the engine block, it begins running. The PCV valve contains a spring-loaded plunger, which plays the function of redirecting the gas flow out of the crankcase and into the intake collector. The gases then flow back into the engine's combustion chambers, where they burn again during the next combustion process.
Where is PCV valve located?
In general, the PCV valve is located in the valve cover where it is plugged into a rubber grommet. It can be found mostly on or near the intake manifold. A clamp holds a hose which leads to the PCV valve.
