Is an EVR Valve Right For Your Car?

If you’re looking to reduce the emissions from your car, you may be wondering if an EVR valve is right for you. This technology can help reduce nitrogen oxide emissions from internal combustion engines, such as gasoline and diesel engines, and some hydrogen engines as well. Essentially, this system works by recirculating some of the exhaust gas back into the engine’s cylinders, where it is burned again.


A faulty EGR valve is a serious issue, which can affect the performance of your vehicle. It can make your engine run slower than normal, and can decrease the power of your car. It can also cause the air-fuel ratio to be out of balance, which can reduce fuel efficiency and increase fuel costs.

A faulty EGR valve can also lead to a rough idle, which can make your car feel rough. In addition, it may cause the steering wheel to misfire or bounce off the seat. It is important to repair this problem as soon as possible, because a malfunctioning EGR valve can cause further damage.


If your vehicle has a faulty EGR valve, you should consider getting it repaired. It may not be dangerous to drive, but it can affect the car’s emissions. You should contact a certified technician for help. You can also clean it yourself. But remember to be thorough – the EGR valve can become stuck or damaged.

To begin, you must first determine the type of valve that needs replacing. ThereĀ evr valve are two kinds of EGR valves: universal and direct-fit. The former requires a new EGR valve, while the latter is compatible with older vehicles. A replacement valve must be calibrated to fit the vehicle’s engine. To find this out, you can look in the car’s manual or check the small plate located on the dashboard. Make sure that the valve is cool enough to touch before attempting to replace it. Also, make sure that you disconnect the valve from any electrical wiring and hoses that go to it.


Proper maintenance of your EGR valve is essential to keeping your vehicle running at its best. By performing a simple cleaning of the EGR valve, you will not only improve the performance of your vehicle, but it will also protect your engine. In fact, regular cleaning of the EGR valve can save your engine from significant engine damage.

To clean the EGR valve, first remove the gasket and spray it with a good cleaner. This cleaning solution will remove any carbon build-up that may have accumulated in the valve and its connected components. You can also use a carb cleaner to clean the metal connecting pipes. It is also a good idea to use a soft brush to remove stubborn carbon deposits. Make sure not to contact the electrical connectors, rubber hoses, and plastic parts with the cleaning solution. Before you begin, turn off your vehicle’s CEL (Check Engine Light) and make sure that your engine is not running.


The price of an EGR valve varies. There are two basic types: electronic controlled and vacuum operated. Electronically controlled valves are more complicated, and they can cost more than $150 a piece. If you’re replacing an old valve with a new one, the cost will likely be lower. If you’re replacing a new one with a vacuum operated valve, the cost will be higher than if you’re replacing a new one with an electronic one.

The EGR valve helps improve fuel efficiency and reduce the amount of nitrogen oxides entering the atmosphere. These pollutants cause lung and eye irritation and are a major ingredient of the brown haze we call smog. The EGR system also reduces the temperature of the combustion chamber. This reduces heat stress on the valves, allowing for more precise ignition timing without pre-ignition.
