Diesel Intake & EGR Carbon Cleaning
Is your Car Breathing Properly?
If you notice your car seems to be suffering from poor fuel economy, is lacking power when accelerating, displays an overall lack of power or the engine seems to be unusually hot all the time, it could be time for a carbon clean.
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.
Why Get a Carbon Clean
Since 1999 most cars in built in Australia will have an EGR system of some kind. If your vehicle happens to be fitted with an EGR system, there is something you should know. Carbon buildup in Intake Manifold and EGR Valves could be choking your engine.
This is commonn in 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. Les Haldane Mechanical Gawler have the skills and equipment to give your engine a full carbon clean. This helps ensure correct fuel mix, improve efficiency and fuel economy and generally assists in protecting the engine.

NOx (or Nitrogen Oxide) is produced by an engine during the combustion cycle. Nitrogen Oxide considered to be very harmful to the environment.
The EGR system 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.
As blow-by gases from the combustion cycle escape past the Piston Rings they become trapped inside the crankcase, causing pressure to build up, facilitating the builld up of sludge and reducing 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.
When the oil, allowed through by a PCV Valve, turbocharger shaft or air compressor, meets the recirculated NOx Gases within the Intake Manifold problems become apparent. When mixed, a build-up of sticky Carbon deposits is formed, slowly solidifying over time and effectively choking the system. EGR valves are also affected by 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 completely replaced.
