Diesel TerraClean Service

Terraclean is a highly advanced patented cleaning system that requires unique machinery  that connects to your vehicle using high quality OEM adaptors. The TerraClean machine takes over as the vehicles fuel tank and fuel pump. This unique process enables the cleaning of internal engine components without dismantling the engine! This process is called Decarbonising, sometimes called Decoking or to Decoke, the majority of carbon deposits, tars and varnishes will be cleaned away from your: fuel injectors, fuel injection pump, combustion chambers, valves, manifold, oxygen sensors.

Is your vehicle showing Symptoms of Carbon Build Up!
  • General Vehicle performance issues, feeling sluggish etc

  • Rough Idle or Running rough

  • Flat spots in acceleration

  • Poor vehicle emissions, and excessive exhaust smoke

  • Poor fuel economy or MPG

  • Excessive cranking

Keep Your Vehicle Professionally Decarbonised

Regular servicing and maintenance should never be overlooked. By keeping your vehicle Carbon free with a regular TerraClean service you can improve fuel economy by 4 – 16%. TerraClean equipment is the best we have seen, simply put it will clean from your engine right through to the tip of your exhaust!


What’s cleaned by the TerraClean Diesel Treatment?

Exhaust and Emissions

Modern diesel engine vehicles are lean burn engines; this presents a problem to your exhaust emissions as they naturally produce more carbon particulates or soot than a petrol engine. This is why diesels generally have more problems passing exhaust emissions test.

Exhaust emissions pollutants include hydrocarbons (HC), Carbon Monoxide, Nitric Oxide and Nitrogen Dioxide, as well as soot or carbon particles. You may have heard the term ‘NOx emissions’ this term is for both Nitric Oxide and Nitrogen Dioxide combined. Both Carbon Monoxide (CO) and hydrocarbons (HC) levels are very important in passing your exhaust emissions test.
A Diesel Terraclean Treatment will remove hard baked carbon and soot from your engine, injectors, exhaust system, and sensors resulting in a cleaner and greener burn for your diesel vehicle, thus reducing harmful exhaust emissions.

Diesel Lambda Sensors or O2 Sensor

A Diesel lambda sensor is mounted inside the vehicles exhaust system; it measures how well the diesel fuel combustion is occurring inside the engine. The amount of diesel fuel allowed into the engine is controlled by the Electronic Control Unit also known as the ECU; this is the engines on board fuel injection computer or the brain.
The object of the sensor’s operation is to allow the engine ECU to adjust the amount of fuel allowed into the engine for best fuel economy and lowest emissions. If the Lambda Sensor/O2 Sensor becomes clogged with carbon deposits and soot it cannot perform its job properly. This will result in the ECU receiving incorrect information from the sensor, which compromises the efficiency of the engine, resulting in poor performance, lower horse power as well as poorer fuel consumption.

Catalytic convertors

The job of the catalytic converter on your diesel vehicle is to convert harmful pollutants into less harmful emissions before they leave the car’s­ exhaust system. During the last fifteen years or so, much time has been spent on developing catalytic converters for diesel exhaust systems, especially for carbon particulate emissions (soot), which is the primary cause for concern in your diesel exhaust.
Catalytic convertors have massively reduced emissions from diesel vehicle engines and have greatly improved our air quality – without them in fact it would be virtually impossible to sustain the number of diesel vehicles we have on our roads today.
Carbon and soot build up inside your catalytic convertor and is a big problem for diesel vehicles. A sooty exhaust pipe can be indication of a clogged catalytic convertor.

Diesel Fuel Injectors

Diesel fuel injectors that are functioning properly and clean are key to getting the best performance and mpg from your diesel vehicle. Clean fuel injectors will inject diesel fuel into the combustion chamber in an atomized-mist that burns cleanly and gets the best out of the fuel.
Over time, carbon deposits build up on the tips of fuel injector, which bakes hard and turns into varnish like deposits that affect the optimal spray pattern of the diesel injector. It is therefore vitally important to keep your diesel fuel injectors as clean as possible in order to help restore performance back to the way it was when new.

A word of Caution:
Unfortunately there are some references on Internet forums that encourage the practice of adding petrol to diesel fuel in order to clean your diesel injectors. DO NOT DO THIS! Petrol can strip essentially lubricating oils from your diesel fuel system and parts, like the common rail injection system and high pressure fuel pump resulting in expensive repair. This practice is completely outdated and we strongly advise against it with any modern diesel vehicle!

Diesel Fuel Pump

Your diesel fuel injection pump is like the heart of the diesel engine. It precisely delivers diesel fuel and maintains a rhythm or timing which keeps your diesel engine running smooth. Simultaneously, the fuel pump also controls the amount of diesel needed to attain the desired power. It does this by supplying diesel fuel to the injectors via the high pressure fuel rail or common rail.
Keeping your fuel pump clean and well lubricated will improve the life of this very expensive component. If your fuel pump is dirty or has had poor quality fuel or even worse the wrong fuel ran through it then it is highly vulnerable to damage which may result in expensive repair or replacement.

Combustion Chamber

A natural by-product of combustion is carbon; this black soot like substance deposits itself and hardens on the cylinder head, cylinder wall, pistons and valves. Carbon deposits collect in the combustion chamber and will affect engine performance, resulting in higher oil and fuel consumption, engine knocking or overheating.
Put simply, decarbonising your engine also known as decoking, involves the removal of carbon deposits from the combustion chamber, pistons and valves in your engine. Before TerraClean this procedure was hard manual work and time consuming, cleaning out carbon deposits would normally require removal of the cylinder head and then, physically scraping off carbon deposits from the top of the pistons, the combustion chamber and other components.

Our TerraClean diesel treatment  will clean away most of the carbon deposits in the same way as a full engine strip! Resulting in a more efficient burn
