TerraClean Petrol fuel based Decarbonising Service.
Over time, all petrol engines build up carbon deposits in combustion chambers, exhaust ports, catalytic converters and on lambda sensors. Additionally, all petrol injection systems build up gums, tars and varnishes. Both these contaminants have a negative effect on your engines efficiency which we’ll explain how and why.
Petrol is a combination of two core components, Aromatic fuel and Aliphatic fuel. These two components are necessary to allow the fuel to achieve an optimum combustion rate as well as achieve optimum power.
Aliphatic fuel has a very loose molecular structure meaning that it burns very easily and almost completely combusts leaving little or no carbon deposits behind in the combustion chambers, but it creates very little power, which is why it’s blended with aromatic fuel which is very powerful. However, this is where the problem starts.
Aromatic fuel has a very tight molecular structure making it very difficult to burn and it relies on the aliphatic fuel to start the combustion process. Because of the tight molecular bond of the aromatics they never completely combust and leave behind carbon deposits which form in the combustion chambers, exhaust ports, cats and on the lambda sensors.
This carbon build up has a negative effect on engine efficiency as the fuel is now burning in a dirty environment (combustion chambers) which also restricts the performance of cats and lambda sensors.
But that’s not where it ends as over time inlet valves and ports on manifold injection engines, fuel injectors on all engines and fuel pressure regulators (if fitted) suffer from a build up of tars, gums and varnishes. This then slows down the injector reaction times, causing fuel timing problems, it impairs fuel atomisation causing incomplete combustion, it can also reduce fuel rail pressure, and in some cases can coat the inlet valves causing cold start miss fires.
This is where a TerraClean service is different from any other engine/injector cleaning service. TerraClean is the only service that has two stages of cleaning.
The first stage cleans the injection system and inlet valves (manifold injection only) which restores functionality to injectors and fuel pressure regulator resulting in improved fuel pressure, timing and atomisation.
On manifold injected engines it cleans inlet valves and ports of sticky deposits allowing improved flow of fuel vapour into the engine. This all results in cleaner fuel burn reducing the presence of Hydrocarbons caused by un burnt fuel in the exhaust gassed.
The second stage of the process is where the science begins. Using aliphatic only fuel, this fuel while passing through the TerraClean machine goes through a process called columbic fractionation, and it is given a passive negative electrical charge.
This breaks down the molecular structure of the fuel even further, turning it from a liquid into a vapour, and as the carbon in the combustion chambers, exhaust, cat and lambda sensors has a natural positive electrical charge the fuel and subsequent exhaust gasses are attracted to it. This then turns the carbon into carbon dioxide which exits through the exhaust tail pipe
What A TerraClean Does:
The end result is cleaner combustion chambers, exhaust, cats and lambda sensors, allowing the ECU or engine management system to react faster to fuel mixture changes and adjust fuel and ignition timing to suit.
The end result is an engine that is more efficient, has better and quicker throttle response, runs smoother and quieter, and has improved emissions and mpg.
