What Does an EGR Valve Do?

Gases that enter and exit your car’s engine are essential, and often overlooked. The intake and exhaust systems perform vital functions that improve a car’s efficiency, performance, and environmental footprint. Fortunately, companies like DynoVox have specialized in creating the best intake and exhaust parts for your vehicle.

What is an EGR Valve?

EGR stands for exhaust gas recirculation, meaning this part involves how gases flow into the combustion chamber, and out of the vehicle. An EGR valve is an emission control device that helps maintain the combustion chamber temperature inside the engine and reduce the amount of dangerous nitrogen oxides introduced into the atmosphere.

The way that the EGR Valve achieves this is by precisely reintroducing exhaust gases back into the combustion mixture and diluting it. The resulting mixture burns at a much lower temperature, which in turn causes less nitrogen oxide to be produced, resulting in a cleaner exhaust.

Functionally this works by opening the valve by a certain percentage based on the current combustion gas makeup. For example, if a car is idling, less power is needed, so the EGR valve remains nearly fully open, diluting the combustion gases significantly. Alternatively, at higher speeds, the EGR valve can be closed entirely to ensure that plenty of oxygen is entering the cylinders.

Common Issues with EGR Valves

EGR Valves are constantly subject to high temperatures and exhaust gases. The primary reason why an EGR Valve fails or becomes damaged is through carbon buildup. Over time, the exhaust gases exiting the vehicle will clog the tubes and eventually the valve itself. Additional common failure points are perforation in the tubes or even a break in the valve’s casing.

A faulty EGR Valve can potentially have several symptoms, some of these symptoms include:

  • Check Engine Light – Due to how an EGR Valve is tied directly to the engine’s combustion, this light may come on to indicate an issue.
  • Odd Knocking Noises – Nitrous oxides have a higher burning temperature and volatility. A detonation will be more potent and cause an audible knocking noise.
  • Performance Issues – Because the EGR Valve’s primary function is diluting combustion gases, a faulty valve could consistently reduce the amount of oxygen in the combustion chamber, reducing performance.
  • Reduced Fuel Efficiency – Either less gas or more gas can be burned thanks to a faulty EGR Valve depending on how it has failed.

Introducing EGR Delete Kits

Due to the multiple points of failure, and how an EGR Valve is tied directly to a car’s performance, the removal of the EGR system through an EGR Delete Kit is becoming a popular choice. A reputable company such as DynoVox offers a wide range of high-quality EGR Delete Kits for many different models and makes of vehicles, boasting easy installation and affordability.

An EGR Delete Kit is aptly named, as its goal is to remove the EGR system entirely. Seeing as how the EGR system is directly responsible for reducing the amount of oxygen that enters the combustion chambers, removing it can easily improve performance drastically. Not only does an EGR Delete Kit allow the combustion chambers to have much more oxygen, but it also reduces the amount of carbon buildup in the entire exhaust system.

Conclusion

If you want to reduce maintenance costs, increase performance, and improve efficiency, an EGR Delete Kit can be an easy solution. However, an important question remains unanswered: How much does it cost to replace an EGR delete kit?

DynoVox currently has 10% OFF for all EGR Delete Kit by using code LA10 at checkout. As mentioned previously, DynoVox specializes in intake and exhaust systems. The company offers high-quality parts, and we strongly recommend checking out what they offer for your vehicle.
