CARBON DOCTOR SOUTH AFRICA

Modern petrol and diesel engines create carbon deposit build-up on the inner walls of the intake system due to strict emission control devices such as EGR (exhaust gas recirculation) and the use of low viscosity oils. 

Carbon cleans are specifically carried out on direct injection engines.  The main difference between direct and port injection is where the fuel injectors are located in the engine. With direct injection engines, the fuel injectors will be located within the actual engine cylinder. With port injection engines the fuel injectors will be located in the air intake of the engine.

Carbon build-up manifests as a thick black sludge that severely inhibits the performance of your vehicle.  Carbon deposits occur on the inner walls of the intake system and directly on the intake valves.  

Carbon Doctor utilises the walnut blasting method which cleans all carbon build-up on the intake system and valves.
