How Often Should the Combustion Chamber Carbon Deposits Be Cleaned?

[JuneLynn]

Engine combustion chamber carbon deposits are generally cleaned every 2 years or approximately 40,000 kilometers. Below are the relevant details: 1. Function: The combustion chamber is a device where fuel or propellant burns to generate high-temperature gases. It is a combustion apparatus made of high-temperature-resistant alloy materials, forming the space between the piston top and the cylinder head when the piston reaches the top dead center. Fuel burns in this chamber. 2. Hazards: Over time, carbon deposits accumulate in the intake tract, valves, and combustion chamber. These deposits absorb fuel when the engine is cold and release fuel when the engine is hot, leading to difficulties in cold starts and higher fuel consumption when the engine is warm. This results in degraded engine performance, manifesting as idle shaking, poor acceleration, increased fuel consumption, and excessive exhaust emissions.
