What does a PCV valve does?

Your vehicle has two types of valves, the intake and exhaust valves. The engine runs on a combination of air and fuel. When the engine runs, a vacuum is created in the intake manifold. This vacuum draws air into the engine. During normal engine running, when the intake valve is open, the vacuum draws in air and the fuel-air mixture is drawn into the cylinder.

The exhaust valve is responsible for pumping out the burned gas after the engine runs. The pcv valve is a vacuum-relief valve that helps to control the pressure level in your crankcase.

It works automatically, so you don’t need to do anything about it. The valve is fitted to the intake pipe right where the air intake pipe connects to the air box. It is there to prevent the intake air from the atmosphere from entering the crankcase. The crankcase is under slight vacuum pressure, and the valve is usually mounted to a plastic hose.

What does a PCV valve know?

The pcv valve is a small component that monitors the level of fresh air in your engine. It knows when there is an air leak somewhere in the system, and it has a separate drain for the refrigerant that is circulating inside the system.

When the level of air in the engine drops under a certain level, the PCV valve will block the refrigerant from entering the engine. This is to help prevent the engine from overheating. A crankcase ventilation system is designed to remove excess oil, gas, and other gasses that build up in the engine compartment and crankcase.

The PCV valve is located on the engine intake hose and is responsible for the portion of the removal process that occurs after the crankcase pressure has been equalized with the air intake pressure. The vacuum created by the intake air across the filter is known as “crankcase pressure” (PCV).

What does a PCV valve do?

The purpose of a PCV valve is to reduce the loss of engine coolant due to evaporation in the engine. The PCV (positive crankcase ventilation) system cycles a small portion of the hot engine oil/coolant into the atmosphere through your car’s breather system.

However, a clogged or broken PCV valve will allow coolant to leak out of your engine and onto the ground. A clogged or broken PCV valve can damage your engine, and it Much like the radiator in a car, the PCV valve is a crucial element in cooling off the engine’s vital fluids.

During the compression stroke of the engine, some of the pressurized gas is forced through the PCV valve and into the crankcase where it mixes with oil to create a lubricant. The oil is then returned to the engine’s vital components (e.g., pistons, valves, etc.) to help keep them lubricated and running smoothly.

Aside

What does a PCV valve mean in English?

A PCV valve is a little bit of technology that’s fitted inside your car’s air intake system. It removes any excess moisture from the air that passes through your engine. It does this by making use of the pressure difference between the intake air and the atmosphere. This difference in pressure causes the vapour to “bleed” off.

The PCV valve is a small component that’s part of the induction system on most vehicles with a petrol engine. It’s basically a pressure relief valve that’s incorporated into the air intake system. It traps air and oil vapours before they reach your engine.

If the engine becomes pressurised, it can potentially damage your engine and cause a loss of power.

What does a PCV valve mean?

A PCV valve is typically found on older vehicles -- between 1-5 years old -- because it’s a common failure on older cars. It’s a plumber's nightmare because it’s often difficult to diagnose where the leak is coming from, especially in engines with multiple service bays. A PCV (positive crankcase ventilation) valve is a device that routes positive gasses (gases that are created when the combustion process in the engine takes place) back into the intake, rather than simply letting it escape into the atmosphere. It does this by combining the crankcase’s blow-by gas with some intake air to create a pressurized stream. The pressurized gas helps reduce the creation of carbon dioxide emissions, which are responsible for global warming.
