Can Your Car Breathe?
If your vehicle is suffering from poor fuel economy, a lack of power when accelerating, an overall lack of power or the engine seems to be abnormally hot all the time it could be time for a carbon clean.
Then maybe your vehicle needs a diesel anti carbon clean..
A clean intake and fuel system on a diesel engine is critical in order to deliver smooth power and torque with reduced fuel consumption. The system uses a powerful cleaning fluid that runs through the machine and into the vehicle fuel system, and is complimented by a fuel tank additive component that continues the cleaning process for the critical period after the machine clean to ensure the best possible result.
Diesel engine intake and carbon cleaning is an essential but often overlooked part of maintaining a modern diesel engine. Most people do not realise how much carbon builds up in their engines. It accumulates on pistons, rings, valves and injectors. Build up in EGR valves and intake manifolds causes engines to run rough, have reduced power and use more fuel.
Since 1999 most cars in built in Australia will have an EGR system of some kind. If your vehicle is fitted with an EGR system there is something you should know. Carbon buildup in EGR Valves and the Intake Manifold could be choking your engine.
This can happen to both petrol and diesel engines but turbo and diesel engines tend to be more susceptible to the problem, especially where a PCV system is used. Medlyn's Auto Services have the skills and equipment to give your engine a full carbon clean to help ensure a correct fuel mix, improve efficiency and fuel economy and generally protect the engine.
What is EGR?
Fitted to modern common rail diesel engines in order to meet Australian Design Rules (ADR's), the EGR system is a form of emission control designed to reduce emissions of harmful NOx gases into the environment.
What does EGR do?
NOx (or Nitrogen Oxide) is produced by an engine during the combustion cycle and is considered harmful to the environment.
The EGR recirculates some of this NOx back through to the intake side of the engine to help maintain lower combustion chamber temperatures, minimising the amount of NOx emitted.
What is a PCV Valve?
As gases from the combustion cycle escape past the Piston Rings (called blow-by gases), they become trapped inside the crankcase, causing pressure to build up, promoting the build up of sludge and shortening the life of the oil.
This pressure must be relieved and this objective is achieved via a process known as Positive Crankcase Ventilation through the PCV Valve. While necessary to avoid damage to seals and eventually the engine, this process also releases small amounts of engine oil back into the intake at the same time.
What causes Carbon Buildup?
When the oil allowed through by a PCV Valve, turbocharger shaft or air compressor meets the recirculated NOx Gases within the Intake Manifold it becomes a problem. When mixed, a build-up of sticky Carbon deposits is created, slowly solidifying over time and effectively choking the system. EGR valves are also affected by carbon buildup.
What are the effects of carbon buildup?
Over time this build-up restricts air flow to the point where efficiency of the engine becomes impacted and fuel economy suffers. In very serious cases it could even end up with damaged seals and the engine needing to be replaced.
