Problem with PCV ValveProblems with Using only the PCV Valve

All internal combustion engines produce crankcase gas as a result of the explosion in the combustion chamber pushing a portion of the fuel air mixture past the piston rings into the crankcase. Consequently, engines have a mandated process known as Positive Crankcase Ventilation (PCV) in which the crankcase gases are carried out of the crankcase by a hose containing a PCV valve, and are routed to the intake of the combustion chamber to be burned. In addition to containing combustible unburned fuel vapor, which is basically fuel that was pushed past the pistons and into the crankcase, the crankcase gases also contain numerous non-combustible vapors such as contaminated/burnt oil, water, and soot, which when introduced into the combustion chamber interfere with the burning/combustion process of the air and fuel mixture and cause the combustion to be less effective and efficient. As the non-combustible vapors are only partially burned, some of them become soot and are expelled through the exhaust system and some become carbon, which is deposited on the pistons, valves, and spark plugs resulting in more inefficiency in the engine as time passes, and more exhaust emissions.

Fuel and Air Saver Technology with PCV ValveFASTechnology™ Removes Contaminants

The Fuel and Air Saver™ technology is a revolutionary system that installs between the PCV valve and the intake to the combustion chamber. As the crankcase gases enter the Fuel and Air Saver™, the patented separation process which incorporates nine laws of physics, separates and captures the harmful and non-combustible vapors such as contaminated oil, water, and soot from the unburned fuel vapors. Heavy contaminants such as oil, water, and sooty vapors, condense into a liquid form and are captured at the bottom of the container. The lighter unburned fuel vapors, which are in a gaseous state, are free to be routed back into the intake of the combustion chamber to be burned. The liquid that settles in the container is disposed with the crankcase oil during routine oil changes. By preventing contaminated oil, water, and heavy sooty vapors from entering the combustion chamber, numerous benefits are produced, including reduction of crankcase oil contamination and increase in fuel economy.

Benefits of the Fuel and Air SaverBenefits: Better Fuel Economy & Longer Engine Life

By removing the oil from the fuel & air mixture, the driver may feel an increase in engine power. Field tests have shown a fuel savings after only a short period of time. Gasoline is a solvent and actually begins cleaning the engine by eroding away carbon buildup. This cleansing action helps to restore many internal parts of the engine. Removing the carbons from the piston heads permits a more efficient fuel and air combustion and removes the insulation effect which prevented a complete burn.

One of the byproducts of having the Fuel & Air Saver™ installed is longer engine oil life, which equates to longer engine life, which is due in part to the engines combustion chamber and fuel/air mixture is no longer contaminated with water, sooty vapors and burnt oil. When the engine burns cleaner it produces the same horsepower with less fuel. Owners are claiming fuel economy & savings from 5% to 30% depending on vehicle condition and driving habits.
