PCV Valve


Bzzzzzzzzzzt!!!!!!!!

PCV expands to Positive Crankcase Ventilation. PCV Valve is not a pleonasm.

valve

Interesting etymology for that word. In Middle English, valve had two meanings: (1) leaf of a (folding) door and (2) vagina, vulva (link). The origin is Latin where it means 'folding door' or 'leaves' thereof. The Latin words valva and volva go back to the PIE root *wel- 'to turn, wind, roll'.

then there is the Pollution Control Valve (PCV), which is what most people probly (erroneously?) think of.

I never heard the Pollution Control Valve thing...is it the same as the Positive Crankcase Ventilation valve? As you can probably see, I'm not very good at the whole engineering thing )

I see by Acronym finder that there is also a Pollution Control Valve and a Product Control Valve, so I guess I'm outvoted.

Thanks for that site.
