Crankcase Ventilation System on The Jeep CJ3B Page
Crankcase Ventilation System People often ask about the purpose and necessity of the "positive crankcase ventilation" (PCV) fittings found on the F-head engine. The engine was built with a vent either from the top or the side, connected to the intake manifold which would inhale and burn gases from the crankcase.

Crankcase ventilation - Austin Texas News
In the process of combustion, several gases and vapors are formed, and some of them could potentially cause damage to your engine if they're not vented. These gases could lead to corrosion, rust, or the formation of sludge.

Positive Crankcase Ventilation (PCV)
PRINT VERSION Positive Crankcase Ventilation (PCV) 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.

(WO/1996/021101) INTERNAL COMBUSTION ENGINE CRANKCASE VENTILATION SYSTEM
1. A ventilation system for internal combustion engines to recover blow-by gases from a crankcase of an engine, comprising: a positive crankcase ventilation valve (PCV valve), said PCV valve coupled to the engine to receive exhaust gases therefrom; and a recovery filter coupled to said PCV valve, said recovery filter connectedly coupled between the crankcase of the engine and an intake thereof for gas flow through said recovery filter between the crankcase and said intake, whereby hydrocarbons may be collected and noxious gases reduced.

Positive Crankcase Ventilation valves, aka PCV valves. They pull fresh air into the engine’s crankcase and draw fumes out.

Positive crankcase ventilation | WOAI.COM: San Antonio News
Four of the most important emission control systems used today are the catalytic converter, air injection system, EGR or Exhaust Gas Recirculation and Positive Crankcase Ventilation. The latter system, positive crankcase ventilation or PCV, is designed to collect any gases that leak past the piston rings and into the crankcase.

Engine: Crankcase Ventilation
Description: The crankcase ventilation system, often called positive crankcase ventilation (PCV), consists of a PCV valve or metered orifice (calibrated opening), its vacuum hose or line, a supply hose providing air into the crankcase, and on some applications, a breather filter to clean the air provided to the supply hose. Purpose: The purpose of the PCV valve is to regulate the flow of crankcase fumes into the intake manifold where they can be burned.

Saturn PCV Valve (Positive Crankcase Ventilation) - SW SL VUE L100 L300- OEQ Crown
Toughen the “crank” in crankcase with the Saturn PCV Valve In a car, the crankshaft or the crank is a device that is used to translate reciprocating linear piston motion into rotation. It typically connects to a flywheel, to reduce the pulsation characteristic of the four-stroke cycle, which creates a torsional or vibrational damper at the opposite end in order to reduce the torsion vibrations caused by the length of the crankshaft.

Sect. 4, Ch. 3: Pulmonary Minute Volume
 This relationship is analogous to cardiac output ( ), which is computed by multiplying stroke volume by the number of beats per minute (heart rate). A portion of each V T (or of E ) reaches the gas exchange sites (alveoli), while a smaller portion ends up in the conducting airways, where no gas exchange occurs. Thus, minute ventilation is divided between alveolar and airway ventilation. Since air that ends up in the conducting airway (nasal passages, trachea, bronchi and bronchioles) does not participate in gas exchange with pulmonary capillary blood, it is referred to as dead space ventilation ( D ), as shown schematically (see bottom figure ).

Positive-Pressure Ventilation
 Source: BUILDER Magazine Publication date: February 1, 2007 By Ted Cushman Q: I'm considering a house ventilation system that pulls fresh air from outdoors into the air handler of my heating and cooling system. Do I have to include some kind of powered exhaust vent also, to compensate for the incoming airflow? A: Modern tight houses do benefit from a reliable, controlled supply of fresh air. There are three ways to provide this: an “exhaust-only” or “negative pressure” setup that blows air out of the house, pulling makeup air in through holes or cracks in the building envelope; a “supply-only” or positive pressure system that draws outdoor air in through a duct, forcing the indoor air to escape through cracks or holes; or a “balanced” system with ducts and fans for both intake and exhaust. The system you describe, a duct from outdoors to the return side of your air handler, is one of the simplest supply-only setups. An add-on control for the heating and cooling system, the AirCycler (www. aircycler.com), will open and shut the intake damper as required and run the air handler fan on a user-specified schedule (typically, for 10 minutes every ½ hour to 1 hour). Building science consultant Terry Brennan explains: “When the air handler comes on and runs 10 minutes in every hour, it greatly increases the effectiveness of your ventilation, by continually mixing the fresh air into the house air. That way, the bedrooms are not under-ventilated, and temperatures are evened-out throughout the building. ” But won't positive air pressure inside the house create a risk of condensation and moisture damage within the cold walls? That question is often raised, says Brennan, but decades of building research have convinced him that over-pressurizing the house is a negligible concern—at least in most of the U. S. Outside of extremely cold climates, says Brennan, “the simple story is that until you get to such high indoor humidity that you would have other moisture-related problems such as window condensation anyway, you can bring in something like 25 to 75 cfm (cubic feet per minute) of outdoor air and pressurize the building with it, without worrying about forcing moisture into the walls.
