What to dismantle for carbon deposit cleaning?

Cleaning of carbon deposits requires disassembly: throttle, fuel injector, intake manifold, combustion chamber, three-way catalytic converter, etc. Carbon deposition refers to the deposits produced after incomplete combustion of fuel and lubricating oil, which are mainly divided into valves, combustion chambers and intake pipes. The formation of carbon deposit is directly related to automobile fuel and lubricating oil. If carbon deposition is serious, it will change the original structural parameters of the engine, reduce engine power and increase fuel consumption. In severe cases, the engine will knock, accelerate abnormal sound, cause damage to the piston and crankshaft, and even eventually lead to oil combustion, which requires overhaul.
