Crankcase valve

A crankcase ventilation system (CVS) is a one way passage for the blow-by gases to escape in a controlled manner from the crankcase of an internal combustion engine. The positive crankcase ventilation (PCV) valve works to evacuate gas from the crankcase of the engine. The PCV valve directs these gases back into the combustion chambers via the intake manifold. This plays a large role in engine efficiency, improving emissions and the overall operation of your vehicle. The crankcase is an important part of internal combustion engines as a bearing for the crankshaft.

Depending on the manufacturer, the definition of the crankcase differs and is equated with the engine block. According to machine manufacturer Franz Pischinger, the crankcase is the combination of cylinder, cooling jacket and engine housing. A crankcase is the housing for the crankshaft in a reciprocating internal combustion engine. The enclosure forms the largest cavity in the engine and is located below the cylinder(s), which in a multicylinder engine is usually integrated into one or several cylinder blocks.

As the pressure inside the crankcase increases the valve raises compressing the spring. The excess pressure is released to the atmosphere. The Oil wetted Gauze assembly prevents the flame in the crankcase from escaping.

The valve closes automatically under the tension and action of spring once the pressure reduces. Additional components may include a check valve in the oil return line and a relief valve or bypass valve that vents blowby gas to prevent crankcase over pressurization if the restriction of the separator become excessive. With a blown crankcase vent valve , however, excessive pressure buildup may happen and lead to mechanical failure. So if you see any sign of oil or gas leak from the crankcase vent valve or any other part of the ventilation system, better check those seals, connections, and gaskets. A bad PCV valve or related component can produce a number of symptoms.

It sends partially burned gases that come from the engine’s crankcase back to the combustion chamber. Through the torn membrane into the engine gets unaccounted mass air flow sensor.

I just finished replacing the crankcase ventilation system. That was just about the most exasperation replacement I have done. Biggest stumbling block was the “jacket” of the valve.

The outlet pressure ( crankcase pressure) of the valve is the closing force within it.

The opposing opening force within the valve is an interior spring. These two forces oppose each other to regulate the port size within the valve. The importance of Crankcase and Valve Cover Venting. Why pulling negative vacuum is important to making power.

Contributed by: Enginebasics. A lot of power is being left on the table by many set-ups popping up lately. When a PCV valve flows the proper amount of air, it will evacuate blowby from the crankcase and draw fresh air into the crankcase through the valve cover breather During this condition, a slight vacuum is present in the crankcase.

This slight vacuum is also helpful in preventing oil leaks.
