The crankcase breather vent valve and PCV heater element are two crucial components of any engine. The breather is responsible for regulating the pressure inside the engine and ensuring that harmful gases and oil mist do not escape into the environment. The PCV heater element is responsible for heating up the PCV valve to improve its efficiency and reduce emissions.
The breather/valve assembly typically consists of a breather valve, a PCV valve, and a connecting tube. The breather valve regulates the pressure inside the crankcase by directing air either into or out of the engine. When the pressure inside the engine is too high, the breather valve opens up to allow air to be released. When the pressure inside the engine is too low, the valve closes to prevent air from entering.
In addition to regulating the pressure, the breather valve also separates the oil mist from the air before it is released into the environment. This is achieved through a series of baffles and meshes that trap the oil and allow the air to escape. This helps to reduce pollution while also protecting the engine from damage.
The PCV heater element is typically located near the PCV valve and is responsible for heating it up. This is important because a cold PCV valve will not work as well as it should, leading to reduced efficiency and increased emissions. By heating up the valve, the PCV heater element allows it to function at peak efficiency, reducing emissions and improving fuel economy.
While there may be a mechanical valve in the breather/valve assembly, this varies depending on the make and model of the engine. Some engines may have a mechanical valve, while others may rely on the breather valve and PCV valve to regulate pressure and emissions.
In summary, the crankcase breather vent valve and PCV heater element are two important components that work together to regulate pressure and emissions in an engine. By understanding how these components work and ensuring that they are functioning properly, you can help to keep your engine running smoothly and efficiently.
