We are a Terraclean Service Centre offering decarbonisation services for both Petrol and Diesel engines.
Carbon deposits build up over time in all petrol engines. This ultimately has a detrimental impact on your engines efficiency and subsequently, this can reduce miles per gallon and the power of your engine. To tackle the contaminants forming in combustion chambers, exhaust ports, catalytic converters (cat) and on lambda sensors, Terraclean can offers a 2-stage cleaning process. Firstly to treat the injection system and then clean the aforementioned; combustion chambers, exhaust, cats and lambda sensors. This allows the ECU to react faster to fuel mixture changes and adjust fuel and ignition timing to suit. This ensures your engine is more efficient with better throttle response, running smoother and quieter improving emissions and mpg.
As you might expect the technology is quite different to clean diesel engines. However, the principles of the process are the same, but the Terraclean machine is specifically designed for decarbonising Diesel Engines. The process involves running your engine on a special fuel to clean both pre and post-combustion providing all the same benefits. The system will clean through both Exhaust Gas Recirculation systems and Diesel Particle Filters, where fitted and providing there is adequate air flow.
Direct Injection Engines are susceptible to carbon build-up on the back of the intake valves. During the conventional fuel system service, the intake valves are not cleaned, therefore these require a separate cleaning process through the induction system.
TerraClean DPF Cleaning
The DPF (diesel particulate filter) sits within a vehicle’s exhaust system and is designed to “capture” soot/diesel particles to reduce harmful emissions. DPFs self-clean through a process called “regeneration”, this happens under certain diving conditions and the particles are emitted leaving only a small ash residue. Sensors in the DPF unit communicate with the vehicles central computer (ECU) to determine when to clean – regenerate the DPF.
There are a number of reasons a DPF might not always regenerate when it should, examples such as driving styles, driving conditions as well as technical reasons are often the cause. As the DPF fills up a warning light can appear on the dashboard. The issue should be rectified otherwise the vehicle’s performance will be affected and in some cases the vehicle could go into “limp mode” and become unusable until the issue is resolved.
A standard Diesel TerraClean service helps to remove particles from your DPF as part of a preventative maintenance programme. However, if the device is too blocked there is a specific tool within the TerraClean range to remove the accumulated particles.
DPF’s can become blocked with Ash and Oil which a standard TerraClean service will not remove. There are specific vehicle solutions available which can remove oil and ash from otherwise heathy DPFs. The TerraClean Service Centre network has access to this facility. This service involves removal of the DPF device from your vehicle for a few days whilst the unit is cleaned via a national service facility. With replacement DPFs costing up to £1000 for most vehicles and even more for those vehicles of a higher specification vehicles, it is worthwhile investigating the cleaning options offered through TerraClean.
