EGR valve cleaner

How to clean your EGR valve properly

Do you need to clean your EGR valve?
Since the 1960s, vehicle manufacturers have installed Exhaust Gas Recirculation (EGR) valves to reduce nitrous oxide (NOX) emissions. The EGR valve recirculates a small amount of exhaust into the combustion cycle. The warmth of the exhaust lets the combustion chambers warm up quickly, while the spent, inert gases keep the chambers from getting too hot when the engine fully warms up. Whether mechanical or electronic, EGR valves open and close to control the gas flow. If left open, the excess vacuum will cause the engine to act like it wants to stall, idling roughly or surging. If the valve stays closed, detonation could occur in the combustion chambers; this knocking or pinging will lower mileage and the lifespan of the engine. To smooth a rough idle or hesitant or surging acceleration, and reduce knocking, clean your EGR valve.
In diesel engines, fouling as a result of soot accumulation and depositing occurs as a result of driving at low revs, eco driving or from making short journeys. If fouling occurs anywhere in the diesel engine, the dirt quickly spreads through the entire intake system, as a result of which the engine starts to run irregularly and eventually it even cuts out. This dirt does not go away of its own accord or from regular motorway driving. The intake system must therefore be pointedly and preventively cleaned.
Do EGR valve cleaners Really Work?
There are some additives on the market that do indeed help keep engines clean. Some can even remove existing deposits left by lower-quality gasolines and help restore your car’s original performance. Chemistry plays a large role in an additive’s effectiveness. Some fuel system cleaners contain polybutene amine (PBA) chemistry and can remove deposits from EGR valve.
Instructions
• Start the engine and let it warm up.
• Remove a flexible hose in the air intake system as close to the air intake manifold as possible
• Let the engine run at 2000 rpm
• With a warm engine, spray EGR cleaner, using the pipe supplied, into the air intake manifold, ensuring as much of the spray as possible enters the engine
• Spray in short intervals to avoid uncontrolled rise of rpm and diesel knocking
• After each spray, wait until the rpm returns to idle before continuing. If necessary accelerate to avoid engine stalling
• Continue this process until the entire contents of the aerosol are consumed
• Let the engine run at idle for a few minutes. Refit the flexible hose
• After this idling period, accelerate the engine several times or drive the car for 3 to 6 miles. Do not exceed 3000 rpm.
• Before stopping the engine, let it run again for at least, 1 minute

Tips & Warnings
The spray can also be used to directly clean the EGR valve.
What are the symptoms of an EGR failure?
• Rough idle and possible stalling
• Loss of power especially at full throttle
• Flat spots when accelerating
• Excessive smoke
• Poor MPG
• Engine management light on
How to avoid the need of EGR valve cleaning? The solution is Carbon Cleaning
The least expensive option, with no need for disassembly and entailing the shortest service time, and which is an alternative to part replacement, is hydrogen treatment via the Carbon Cleaning station. This service works as a preventative treatment, recommended every 15,000 kilometers, but can also resolve existing problems in the engine. This operation costs only €65.

 
Before thinking to change your EGR Valve

Try Carbon Cleaning !

To save money and resolve the problem.

Preventive engine cleaning enables you to restore engine parts rather than replacing them, thereby saving vehicle owners on costly parts, such as a new turbocharger ($ 1.350 - 3.100), catalytic converter ($ 600 - 2.000), DPF ($ 600 - 2.000) or EGR valve ($ 370 - 500).

These problems result mainly from poor combustion, which stifles the engine.

So before replacing your engine parts, try Carbon Cleaning. A dirty engine as the result of carbon deposits is the new threat to vehicle performance.
