What is Carbon Build Up?

What is carbon build up? In order to understand where carbon comes from a quick explanation of how an internal combustion engine functions is helpful. Vehicles use air, fuel, and spark to create the boom effect inside the engine. Air is sucked into the air intake manifold by the engine and inside this intake manifold contains fuel injectors that spray fuel into the manifold, the fuel then mixes with the air and is delivered to the combustion chamber through the intake valve, this process is called port injection. Carbon is a by-product of the internal combustion engine and is ultimately unavoidable. Carbon build up happens when fuel in the combustion chamber is not fully burned and leaves a dark sticky residue on the surface it comes into contact with. On older vehicles the carbon build up was not as prominent as it is in newer models. This is because the fuel is delivered within the air intake system, as the fuel runs down the intake valve and is delivered into the ... read more
