Terraclean Diesel Process Described

Why Do Diesel Engines Need TerraClean?

Unfortunately it’s a fact that all Diesel engines will eventually build up deposits of carbon in their combustion chambers, exhaust ports, turbo and catalytic converter. It’s also a problem that’s getting bigger on modern Diesel engines, and the reason is due to lower combustion temperatures.

In order for carbon to burn, a combustion temperature of over 550 degrees C has to be achieved, and this where the problem lies in all modern Diesel engines, because they are fitted with emissions control systems that have a way of reducing the combustion temperature to around the 350 degrees C mark. 

This system is called Exhaust Gas Recirculation or more commonly EGR.

The reduced combustion temperature are there to lower the amount of Nitrogen Oxides (NOX) that are emitted from the vehicle exhaust into the atmosphere.

This is good news for the air quality but not so good news for the inside of your engine!!

You Can Benefit From A TerraClean If Your Engine Has:

Done More Than 12k Miles

Carbon build up starts to occur around this time. Using the TerraClean service will act as preventative maintenance.

Dropped In Power & MPG

Carbon deposit may be hindering your vehicles overall performance. Removing the deposits will restore your power.

Failed An M.O.T On Emissions

TerraClean helps to reduce the emissions that your vehicle omits. By using the service you can safely pass your MOT.

The Diesel Engine TerraClean

How Does It Work For Diesel Engines?

The way a diesel TerraClean works is by disconnecting your engine from your fuel tank, the machine is connected to the engine fuel lines and it then runs on the highly refined fuel inside of it. 

This fuel is very rich in additives which perform the cleaning process. Additionally, the difference that sets TerraClean apart from any other decarbonising or injector cleaning service is that the process cleans both pre and post combustion.

The TerraClean process removes gums, varnishes and carbon deposits from the injectors, which improves injector response times, reducing knock as well as also restoring the spray pattern. All this results in improved atomisation which creates a cleaner burn.

It doesn’t end there though, because once the fuel has burned, there are additives contained in the TerraClean fluid that turn into gasses which oxygenate the combustion chambers, turbo, cat and DPF. 

This allows the carbon to burn at much lower temperatures and it exits the exhaust as carbon dioxide and water.

The end result is improved engine efficiency, which leads to improvements in performance, mpg and emissions.

After the clean it’s been 550-700 miles of range. The best mpg l got on my trip to work was 24mpg and that was coasting A LOT. Doing the same drive now I got 30mpg

To be honest, I thought I would only see a small change in performance. I am however nicely surprised how much greater it in fact is. The car now has so much more grunt and is running so much smoother.

Great customer service from reception to the technicians. I've had my E350 Terraclean and remapped the same time. The car feel's a lot more responsive and smoother throughout the automatic gear changes with plenty of torque to hand for overtaking. Great work and highly recommended.

Had Terraclean service and remap done to my Golf TDI. The car is very much more responsive than before, but haven't done enough miles yet to work our the mpg. The service received was first class and would recommend them to anyone requiring similar work to their vehicle.

…I had to take this opportunity to say how impressed I am with the results. I have noticed an average increase of 6mpg on my normal 100 mile commute, the car is much more responsive and it smokes a little less on first start in the morning. It genuinely feels like it has had 60k knocked off the clock!

My Astra 1.9cdti recently failed Mot on emissions.After having the Terraclean service it flew through the Mot.I strongly advise folk to consider this service to pass the new tougher emission test. A big thanks to AceCarCare.

Hi everyone 👋 definitely recommend ace terraclean to anyone who is thinking of a remap they do a good discount on the both together,and cleaned my car for me,it was like picking a new car up from showroom.
