How many kilometers does it take to clean the combustion chamber?

It is necessary to clean the combustion chamber at 40,000 kilometers. Reasons for cleaning the combustion chamber: After prolonged operation of the car, carbon deposits in the intake tract, valve area, and combustion chamber will increase. These carbon deposits absorb fuel when the car is cold and release fuel when the car is hot, leading to difficulties in starting when cold, higher fuel consumption when hot, and consequently, degraded engine performance, resulting in phenomena such as idle shaking, poor acceleration, increased fuel consumption, and excessive exhaust emissions. Hazards of carbon deposits in cars: Carbon deposits in cars can increase fuel consumption, reduce engine power, and damage the engine. In severe cases, they can cause engine knocking, abnormal acceleration noises, and damage to pistons and crankshafts, potentially leading to oil burning in the engine and necessitating major repairs. They also affect exhaust emissions, directly impacting the car's ability to pass annual inspection tests.
After driving for over a decade, I believe cleaning the combustion chamber shouldn't be rigidly based on mileage. If you frequently encounter city traffic jams and take short trips like I do, where the engine doesn't fully warm up, carbon deposits accumulate faster. Generally, you should consider inspection and cleaning every 20,000 to 30,000 kilometers. Excessive carbon buildup not only affects performance but also increases fuel consumption noticeably, like experiencing sluggishness when climbing hills. Using high-quality engine oil and fuel additives regularly can slow down carbon deposition. Don't wait until obvious symptoms appear, such as difficulty starting the engine, as repairs will cost more then. Paying attention to your car's condition is far more important than sticking to fixed numbers.
As a young car enthusiast who enjoys tinkering with new vehicles, I prefer using the onboard diagnostic system to monitor whether the combustion chamber needs cleaning, rather than sticking to a fixed mileage interval. Modern engines are more efficient and have fewer carbon buildup issues, possibly not requiring cleaning for 40,000 to 50,000 kilometers. However, if the OBD shows abnormal emissions or the engine shakes severely, then it's time to address it. Driving habits are crucial: if you rarely drive long distances at high speeds, the risk of carbon buildup increases. Regularly using cleaning additives or changing the air filter can also be quite effective. Keeping the combustion chamber clean can save you a lot on fuel costs.
