Why you might need your engine carbon cleaned?

First, let's look at the reasons an engine may need to be cleared of carbon at all. Petrol and diesel produce power by burning fuel, and this creates sooty exhaust gasses. Emissions control devices such as catalysts and diesel particulate filters keep the amount of soot that reaches the atmosphere to a minimum, but there are still some that are deposited on elements inside the engine and exhaust the system.
