Is it necessary to disassemble and clean the engine due to carbon deposition?

For carbon deposition, it is not "carbon" in the sense, but a mixture, which contains petroleum hydrocarbons, paraffin, and colloid left by engine oil, dust, debris, etc. when the engine works for a long time. We usually call these combined substances carbon deposition.

As for the cause of carbon deposition, the main reason is that the quality of oil products is uneven, resulting in different levels of residual carbon value. High residual carbon value is the main inducing factor of engine carbon deposition. The second is that the fuel injector does not work properly, which leads to insufficient combustion, thus forming carbon deposits. When the engine deposits too much carbon, it will cause many problems.

When dealing with engine carbon deposits, some drivers want to remove the engine and clean it. In fact, this method is costly and risky. Because it is limited by the removal and cleaning skills, it may cause greater safety hazards, so it is not necessary to remove the engine to clean up the carbon deposit.

Another way is to drive on the highway, because the engine will wash away the newly formed carbon deposits when running at high speed. If you often run at high speed, you don't have to worry too much about the engine carbon deposits.

In the final analysis, it is better to avoid carbon deposition in daily driving than to remove the engine and clean up the carbon deposition. First of all, avoid using inferior oil and use regular fuel. The other thing is to maintain the oil on time, and select regular oil according to the vehicle maintenance manual. In addition, in the daily driving process, the gear should also match the speed, otherwise it will not only cause engine wear, fuel consumption increase, but also cause engine carbon deposition.

When dealing with the carbon deposit in the engine, some drivers also think of using the internal cleaning agent of the engine. This product is an automobile maintenance product used to clean the harmful substances such as oil sludge, carbon deposit and colloid inside the engine, keep the engine clean inside, reduce wear and prolong the service life of the engine.

In the process of use, the detergent added to the engine crankcase will flow with the engine running, making its colloid dissolve, thus loosening and falling off. The cleaned colloid will be filtered by the oil filter or deposited in the oil pan along with the oil circulation, and will be removed together when the oil filter and oil pan are replaced or cleaned.

However, the use effect of cleaning agent is not very obvious, and it has certain harm. This is because the dissolving ability of cleaning agent is relatively strong. When the engine is cleaned too many times, it will cause certain damage to the seals and cylinder block inside the engine.

In short, in daily use, as long as we select and use oil properly, maintain correct driving habits, and carry out maintenance and frequent inspection of the vehicle according to the vehicle maintenance manual, it is not necessary to specially clean the engine carbon deposits.
