Here you can find detailed information about EGR valve cleaner applications. How to use them, how to buy the best, and different products to consider.

What is EGR Valve?

First of all, we need to start from the basics. The EGR valve is a type of valve in car engines that allow the flow of exhaust gases to the engine cylinders for one cycle to burn them one more time. This increases the effectiveness of the engine to burn fuel, fuel efficiency, and performance of the engine. So, a working EGR valve is a must for such engines, especially diesel engines.

But clogs and filth are common problems for EGR valves in general. The most important factor in this clogs and dirt is the burnt fuels and carbon buildup. If the carbon build-up is at a very high stage on the EGR valve, the valve will not work properly. And the performance of your engine will reduce and the mileage of your engine decrease.

So, you need to use EGR valve cleaner applications periodically to take care of this component.

  • If you do not know how to use an EGR valve cleaner, you can consider the easy-to-use applications that we stated above.
  • And also, check the prices. Choose the best application that has the best price. Do not consider the applications that have lower prices than the usual market prices. These applications are not generally high-quality systems that you probably want to buy.

General Causes of Dirt and Filth on EGR Valve

We expect filth and carbon build-up on EGR valve applications in general. Because these systems are directly affected by exhaust gases. This means you need to clean the EGR valves frequently if you want to make them work properly.

But there are some parameters and situations that can accelerate the EGR valve filth and clogs.

  • Short trips with diesel cars: Diesel engines are designed to work in high temperatures and high pressures. And if the temperature inside the cylinders is not high enough, the production of bad smoke will be very high. And if you run your diesel car for short journeys such as tours inside the city, the clogs, and the filth will accelerate in the EGR valve.
  • Fuel quality: Also the quality of fuel that you are using in your engine has a profound effect on the EGR valve. If the fuel quality of your car is not good, the production of bad and harmful gases will be higher. And it will be a higher chance to EGR valves get clogged.

So you need to use the EGR valve cleaner applications frequently to discard these effects.
