TerraClean is a unique decarbonisation technology which makes a significant improvement to the Emissions, MPG and Driveability/Performance of your vehicle.


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.

TerraClean is a revolutionary, advanced and effective decarbonisation solution to this problem, ideal for today’s high compression, multi-valve, direct injection, petrol engines.

TerraDiesel now offers an equally effective solution from the same experts for decarbonisation of modern, high performance diesel engines.

Exhaust Gas Recirculation & Diesel Particulate Filter Cleaning

EGR (Exhaust Gas Recirculation) systems can become clogged with carbon deposits that can cause reduced power, misfiring, smoking and reduced MPG in diesel vehicles.

Cleaning EGR systems has traditionally involved component removal and cleaning by hand or replacement, which are both labour-intensive and expensive. Not any more…

Our new TerraDiesel EGR System Cleaning Tool enables us to clean and restore an Exhaust Gas Recirculation (EGR) system without the need to dismantle the engine. The tool works by applying TerraDiesel EGR and Induction System Cleaner into the system to remove stubborn carbon deposits from the clogged system.

Benefits of the service:

  • Removes carbon deposits from the EGR system
  • Restores performance
  • Improves fuel economy
  • Reduces vehicle emissions
  • Solves variable vein turbo issues such as sticking turbo veins
  • Cleans the DPF (diesel particulator filter)

DPF Cleaning:

Modern diesel vehicles are now fitted with a DPF (Diesel Particulate Filter) as standard as part of European rules that came into force five years ago.

When driving, soot settles on the cell walls of the filter and starts to clog the pores of the DPF unit. This layer of soot can be burnt off during the regeneration process of driving at constant speed for a prolonged period of time, such as motorway driving. During short journeys or city driving, diesel cars do not reach the required exhaust temperature to allow regeneration to take place. If this continues to happen and regeneration is no longer sufficient to clear the blocked filter, motorists can face some very expensive repair costs

Our patented DPF cleaning system means we can clean the DPF without the need of removal from the vehicle saving €€€€€s on labour costs
