Does the Mercedes-Benz combustion chamber need cleaning?

[AnnieRose]

Engine combustion chambers do require cleaning to remove carbon deposits, which helps with engine maintenance and reduces engine wear. Causes of carbon buildup in combustion chambers: Although modern engine technology has advanced considerably, combustion chamber efficiency still only reaches 25% to 30%. Therefore, carbon deposits are primarily caused by mechanical factors and poor fuel quality. The quality of gasoline produced by refineries may vary, resulting in slight differences in the degree of impact. However, using solvent oil or illegal fuel products can lead to more severe carbon buildup. Knocking caused by carbon deposits: Severe carbon buildup in the combustion chamber can increase its temperature, causing the air-fuel mixture to self-ignite simultaneously with the spark plug's ignition. The two ignition points suddenly increase cylinder pressure, damaging internal engine components and producing a sound similar to knocking on the cylinder block, which is known as engine knocking. Solutions for knocking: First, the carbon deposits in the combustion chamber need to be thoroughly cleaned, followed by fuel system maintenance and cleaning.
