How does a crankcase ventilation system work?
How does a crankcase ventilation system work?
Positive Crankcase Ventilation is a system that was developed to remove harmful vapors from the engine and to prevent those vapors from being expelled into the atmosphere. The PCV system does this by using manifold vacuum to draw vapors from the crankcase into the intake manifold.
Is a crankcase breather necessary?
The crankcase ventilation system works to relieve any pressure from the engine’s crankcase attributed to blow by gases by rerouting the gases back into the engine’s intake manifold to be consumed by the engine. This is necessary, as excessive crankcase pressures can cause oil leaks to form if allowed to build too high.
What does a closed crankcase ventilation system do?
The closed system prevents vapor, whether normal or excessive, from reaching the open atmosphere. The closed system is very effective as an air pollution control device. The Positive Crankcase Ventilation (PCV) Valve Commonly referred to as the (PCV) system the flow control valve is the most important part.
How does positive crankcase ventilation ( PCV ) work?
How does a crankcase ventilation system work on a Porsche?
Another type used of the pressure suction type was used on VW Porsche air cooled engines whereby the front crankcase pulley has a reverse screw built into it which brings air into the engine and air escapes the crankcase with the road draft tube. This system works very well in getting rid of crankcase vapors which are harmful to the engine.
When was the first crankcase ventilation system made?
The first PCV systems were built during World War II, to allow tank engines to operate during deep fording operations, where the normal draft tube ventilator would have allowed water to enter the crankcase and destroy the engine.

What makes a racor crankcase ventilation system open?
CV Series (Open Crankcase Ventilation Systems) – Racor’s CV (open) system filters are high-efficiency oil separators, featuring depth-loading, micro-glass fiber Vaporbloc™ media, which is capable of coalescing vapor and contaminants down to 0.3 microns.
