What is the purpose of the Positive Crankcase Ventilation (PCV) system and PCV Valve on Ford Explorer?

The PCV system reduces emissions by scavenging crankcase vapors. Fresh air from the air cleaner mixes with blow-by gases in the crankcase and is rerouted through a PCV valve to the intake manifold. The system includes a replaceable valve, a ventilation filter, and connecting hoses. The valve restricts flow for idle quality. Excessive blow-by gases can flow back into the air cleaner for combustion. Checking and replacing the valve and filter is covered.

Ford Explorer PCV Valve

The subject of this research is the PCV Valve in Ford Explorer automobiles, which plays a vital function in determining emissions and improving the efficiency of the automobile. As an MVAC, the PCV Valve routes combustion byproduct gases back into the engine's combustion chambers thus being environment friendly, and it also checks on the build-up of engine destructive oil sludge. Functioning according to intake manifold vacuum conditions the PCV Valve shuts the gas escape rate at idle to avoid lean running condition and at higher RPMs or under load it allows the increased blow-by gases. The above mechanism helps in the expulsion of crankcase gases in an efficient manner without affecting the operation of the engine. In the same light, the PCV Valve prevent crank case positive pressure events such as turbo charging or back fire. It is important to perform maintenance tasks and services on the PCV Valve from time to time so as to avoid problems such as fouling of the engine oil, oil leaks, and abnormal, high fuel consumption.
