What is the carbon deposition in the parking heater actually washing?

It is obvious that carbon deposition is the residue in the cleaning of fuel injection nozzle, throttle valve, oil pipeline, spark plug and other components. The frequency of cleaning is the throttle valve, which is one of the components most prone to carbon deposition, and it is easy to affect the normal operation of the engine.
