The engine is the “heart” of the car, and its operating quality determines the safety of the traveling experience. With the increase in mileage, the sludge and carbon generated by the engine will precipitate and become a major “stubborn disease” that affects the healthy operation of your car side. To travel safely and ease the aging of the car, it is essential to remove carbon deposits from the car on a regular basis.

Carbon cleaning, also known as “engine decarburization,” removes soot and carbon deposits from the interior of the engine, thereby improving the performance of the vehicle. This article will elucidate the advantages of engine carbon cleaning and the rationale behind decarbonizing engines. Let’s start with a simple definition:

What is Engine Decarbonisation?

Engine decarbonization is the process of eliminating excess carbon deposits produced by the combustion of fuel. Over time, the accumulation of carbon produced by the combustion of fuel can cause damage to the engine’s internal components. The causes of carbon build-up include:
  • The accumulation of waste material resulting from the prolonged use of vehicles;
  • The use of substandard fuel quality;
  • Road conditions: the inability to drive effectively in stop-and-go congested traffic may also accelerate the accumulation of carbon in the engine;
  • The application of excessive force to the accelerator pedal : the application of excessive force to the accelerator pedal can cause gasoline to overflow, yet not be able to burn the gasoline adequately, leading to carbon buildup. 
The combustion of fuel can result in the formation of black smoke, which can subsequently harden on various internal engine components, including injector nozzles, cylinder walls, intake valves, and other components. This hardening can lead to damage to the functionality of these components.

Why do we need Engine Decarbonisation?

Soot, a byproduct of fuel combustion, accumulates around various engine components, including exhaust valves, pipes, cylinder heads, pistons, intake pipes, fuel injectors, and others. Over time, this buildup can impair the functionality of these parts. One effective method for preventing abnormalities is to decarbonize the engine. Another is to clean carbon from specific parts, such as:
  • Combustion chambers
  • Manifold
  • Exhaust pipe
  • Turbo
  • Valve
  • Injectors
  • EGR Valve

When should you Decarbonize your Engine?

  1. Cleaning the throttle: the cleaning cycle of the throttle is generally recommended at 20,000 kilometers;
  2. Cleaning the internal carbon buildup of the engine: the cleaning cycle is generally recommended at 30,000 kilometers;
  3. Cleaning the intake system internal carbon: cleaning cycle is generally recommended every 20000 kilometers;
  4. Injector carbon: 30,000-50,000 kilometers to clean once.

In general, if your car for a long time in the city, it is recommended that the owner of the car 2-3 million kilometers when cleaning a carbon; if long-term driving on the highway can be 3-4 million kilometers to clean.

Still struggling with carbon build-up in your car?

How do you Know if you Need to Decarbonize your Engine?

  1. Observe the exhaust: In the absence of any other factors, the exhaust from a car should be colorless or white. If the exhaust is black and has a pungent odor, it is likely that the three-way catalytic converter has been damaged. This damage cannot be purified, and it can be determined by the presence of carbon deposits.
  2. Increase in fuel consumption: This was attributed to the incomplete combustion of gasoline in the engine combustion chamber, resulting in the accumulation of carbon deposits. In normal daily driving conditions, the same distance was traveled, yet the fuel consumption exceeded the expected range. This indicated the presence of engine carbon deposits.
  3. Decline in engine power: There are numerous reasons for the formation of carbon deposits, which may be found attached to spark plugs or in the throttle. Throttle carbon overload can affect the engine intake, resulting in insufficient intake of gasoline, which in turn impairs the combustion process and reduces engine power. This phenomenon is a contributing factor to both the rise in fuel consumption and the decline in engine power.
  4. Difficulty in starting: If the battery and other car components are in good condition, but the car becomes difficult to start, this may be due to carbon deposits attached to the valves, which affects the engine’s air intake.
  5. Engine shaking: When carbon buildup is severe, carbon buildup on the engine, valves, and injectors can affect the smoothness of the engine’s operation, causing the vehicle to shake badly.

How do you Decarbonize an Engine?

The two most prevalent forms of carbon cleaning are chemical cleaning and logistic cleaning:

1.Chemical Decarbonization The term “no-disassembly cleaning” is also used to describe the process of bottle cleaning. In this method, the cleaning agent is discharged into the intake tract, where it dilutes and softens the carbon, transforming it into a slurry. This slurry is then discharged from the cylinder and out of the combustion chamber. The general cleaning objects include the intake tract, throttle, intake valve, throttle, fuel injector, and the cylinder interior. The advantage of this method is that it can be washed without dismantling. However, the disadvantage is that it is impossible to visualize the cleaning effect.
