Terraclean – Technical Information and History

What is Carbon Build-up

Carbon deposits are the by-product of combustion inside your engine. This build up will affect the efficiency of your engine and typically result in reduced performance, reduced fuel economy and increased emissions.

Keep Your Car Properly Decarbonised!

Proper vehicle maintenance should never be overlooked. Keeping your engine properly decarbonised can improve fuel economy by 4 – 15%. Terraclean is designed to remove carbon from combustion chambers and injectors to safely restore horsepower, lower opacity and restore MPG in diesel engines. In petrol engines, fixing a faulty oxygen sensor can improve your fuel economy by as much as 40%.

So what does Terraclean do and how does it benefit me?

How to keep your diesel car de carbonised

Terraclean is an advanced cleaning system that requires unique patented machinery and chemicals that connect to the vehicle using high quality OEM specific adaptors. The Terraclean machine takes over as the vehicles fuel tank and fuel pump. The process enables cleaning of internal engine components without dismantling the engine!

The majority of carbon, tars and varnishes are removed from; fuel injectors, injection pumps, combustion chambers, valves, manifolds and oxygen sensors. Terraclean can also prevent EGR and turbo vane related problems when used as a preventative measure.*

  • Cleans and lubricates the fuel pump which in turn extends component life.
  • Removes carbon build up from the combustion chamber, this results in a more efficient burn.
  • Cleans the fuel injectors so the spray pattern is restored which gives back lost fuel economy.
  • *Once every 10,000 miles or once a year whichever comes first.

  • Fuel Injector
    Terraclean will remove the varnish and carbon build-up on the fuel injector tips and restore the spray pattern. It has been shown that a varnish layer as fine as 5 microns within the pintle head can restrict fuel flow through the injector by as much as 25%
  • Combustion ChamberTerraclean also removes carbon from within the engine’s combustion chamber and on the intake valves, reducing octane requirements and improving idle and drivability.
  • Oxygen Sensors
    Oxygen sensors get dirty over time from the constant bombardment of carbon, soot and chemicals, which shortens their life. When this happens they can send improper or delayed information to the car’s ECU, which alters the engine’s fuel mixture, causing poor fuel economy, poor performance and excess pollution. Terraclean has been proven to clean and extend the life of your oxygen sensors, thereby restoring fuel economy and performance.
  • Catalytic Converter
    Terraclean has been proven to extend the life of the catalytic converter by removing the carbon deposits from inside.


All over the world competing companies develop decarbonising products by reformulating existing chemical technologies. TerraClean though, like many medical and scientific breakthroughs, was discovered by accident.

TerraClean is the by-product of research being carried out by a group of environmentally conscious Canadian physicists in their attempts to create an ultra low emission internal combustion engine. Their test vehicles were retrofitted with a “molecular injector” so they were operating the “TerraClean” system as part of the vehicle’s on board fuel system. When their technicians stripped down the vehicles to evaluate impact of the technology they identified the fact that there was little evidence of carbon build up. Uncertain if this was due to the vehicles ages they specifically applied the technology to a known older vehicle, operated the TerraClean technology, then stripped down this vehicle too. The point was proven, all the carbon which would have build up in this vehicle throughout its years of operation was gone. Regrettably the running costs of operating a vehicle full time on the chemical solution with the molecular injector as part of the vehicle made the project commercially non viable. BUT, A new idea came to light –

A reverse engineering exercise was then conducted to identify why the TerraClean process had cleaned the engine. Also they extended the technology to consider how to develop the technology further to decarbonise an engine and the entire fuel system.
