Is It Mandatory To Use An EGR Valve?

How to Use EGR Valve Cleaner Spray?

People only use a small fraction of the exiled gases which mix together with fresh air. However, that small fraction of the hot exhaust gases will significantly increase the entire mixture’s overall temperature.

I used a scan tool a few years ago to check something on my car, and I have seen that the air intake temperature was around 48 degrees Celsius.

We’re outside, and it was like 20 degrees Celsius. If we blocked or removed the EGR system, we would have more power and more diesel engine emissions.

If I remove the EGR system, I would see a lot more black smoke at the exit pipes. Manufacturers are forced to reduce emissions by all kinds of organizations around the globe. So introducing the EGR was one of them now.

Our Top 7 Best EGR Valve Cleaners Review

As you know what an EGR valve does for your car and the environment, you surely feel the importance of choosing the right EGR valve cleaner.

Your car engines are designed to be burned hot, but what is the limit? It is 2500 degrees Fahrenheit. When the limit is crossed, it starts producing some harmful gases like Nitrogen Oxides.

A car engine cannot burn fuel alone, but it needs air. It takes air from outside. Nitrogen Oxide is a by-product of fuel, oxygen and nitrogen. When combustion reaction mixes up all these elements at a high temperature, then Nitrogen oxide comes alive.

The most straightforward theory of keeping your engine and whole environment well is to keep your EGR valve clean. It will take care of the rest.

How To Use EGR Valve Cl

Is it mandatory to use an EGR valve?

First of all, you need to find out where your EGR valve is. Generally, it is located at the top of the engine or top right to it. The easiest way to find it is to look into your vehicle model and track down the EGR valve.

There could be a vacuum hose connector in older vehicles. And it is most likely look like a round metal disc, which is three inches across.

There is a sensor on top of the EGR valve in a newer model car, and it is comparatively small sized.

Some electrical harness or a cylinder or something else could be attached to it.

Since every car engine is designed differently, it is wise to follow the exact car manual to find the EGR valve shortly.

However, most of the time, you will find it around the cylinder head.

Arrange some handy tools and safety measures

FAQs About The EGR Valves and Cleaners

FAQs About The EGR Valves and Cleaners

Question: When should I clean my EGR valve?

Answer: Cleaning your EGR valve is a routine work for your car engine. There is no specific time limit to clean, but the recommended distance is 30,000 to 40,000 miles.

You do not need to go to a shop necessarily to clean your EGR valve, but you can do it home.

Here are some common symptoms which will help you to identify:

  • Rough idling
  • Poor fuel economy
  • Failed emission test
  • Smell of fuel while engine is running
  • Unusual noise
  • Engine stalling, and
  • The check engine light comes on

Question: What is the purpose of the exhaust gas recirculation (EGR) system, and how it works?

Answer: The sole purpose of the exhaust gas recirculation system is to reduce nitrogen oxide emissions. It’s currently being used on both gasoline and diesel engines. In the case of diesel engines, we have more nitrogen oxide emissions.

The EGR is pretty efficient when the exhaust gas is actually the cylinders. A small fraction of them will return in the intake, and they will be burned again. By doing this, I reduce the nitrogen oxide emissions by up to 30%, which is pretty significant.

The inconvenient part of the EGR is that it reduces the maximum power output of the engine. An engine has its best performance when it sucks air and when the air is called, it’s denser.

So basically, we have more oxygen to burn when the air is hot. Everything happens all the way around. So the performance will decrease.

Question: How does the EGR actually work well?

How does the EGR actually work well?

Answer: You have a valve which closes and opens depending on how much throttle you apply. The EGR system is almost completely closed at full throttle, whereas it’s pretty much open at lower rpm.

And it recirculates the eggroll gift if you would have a bigger engine v6 a v8 310 etc.

You would have an EGR valve on each side of the engine also in high-performance engines where temperatures go high. The EGR system also has a cooler you could see under the hood.

I’ve seen lots of cars coming in my car shop with EGR problems.

Most of them come with the loss of power and huge smoke emissions. When you have a huge loss of power, the EGR usually blocks, and it sends regular gases to the intake all the time.

So we have two options to remove this problem one is to block the EGR system, and the second is to remove the entire EGR system for the EGR valve. Also, if you don’t want to remove the EGR sy
stem, you can easily remap it.

You can basically tell it when to send the exhaust gasses. I wouldn’t recommend you to remove the EGR system. Because it is a pretty important part of your car. We also need to protect the environment.

Final words

EGR valve is a crucial part of a car, but many drivers don’t give enough importance to it. As this is one of the easiest parts to maintain in your car.

A healthy EGR valve helps to keep the environment better and makes the engine long-lasting. After every 30,000 to 35,000 miles driving, give a check to your EGR valve cleaner. And, don’t hesitate to pick the best EGR valve cleaner for your car!
