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!!
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.
