The so-called 'carbon accumulation' is the product generated inside the engine left by the engine when it is working for a long time, such as oil, dust, and debris. It is commonly called ‘sludge,’ and the sludge in the cylinder is generally called “carbon deposit”. In the normal operation of the engine, the gasoline and the engine oil that normally enters the combustion chamber cannot be completely burned in the cylinder under the condition of insufficient oxygen supply, and the particles of the soot and the lubricating oil are burned. When the engine continues to run. It is further oxidized to a gel and firmly adheres to the top of the piston and the piston ring, as well as the back of the valve, the inner surface of the intake pipe, the throttle body and the combustion chamber. Under the repeated action of high temperature, the gum is changed into asphaltene, resinous and carbonaceous, thereby forming carbon deposits.
There are many reasons for the formation of 'carbon accumulation', but in the final analysis, it is mainly caused by the long-term lack of attention to oil and driving habits. Since gasoline contains waxes and colloids (especially inferior gasoline), these materials will accumulate in the engine over time, and hardened to form carbon deposits after repeated heat. If the engine burns oil, or if the injected gasoline is of poor quality, the valve carbon deposit is more serious and the speed is faster.
It needs to be clear that the impact of engine carbon on the car is very big. As mentioned above, once the engine forms a stubborn carbon deposit, the performance of the car will inevitably be greatly affected, directly affecting the user's driving experience.
First of all, the car's reduced engine power, that is, the power output will become uneven and gradually decay, the car owner's most direct experience is that the car is getting less and less 'powerful', driving more and more laborious, especially when climbing uphill Especially prone to unexpected situations that affect safe driving.
Secondly, carbon accumulation will lead to an increase in fuel consumption of the car, which is obviously directly related to the consumption of the owner. This will undoubtedly increase the economic burden on the owner. In a sense, this is not a good deal for the owner. In this respect, it is also a kind of 'offer' for oneself.
Moreover, it is difficult to make a car cold start, which is the most difficult for the owner to endure. If a car can't always start, it's better to change the bicycle. This is also a test of the psychological quality of the owner. It is a moment of abuse. The owner of this experience must have a kind of change. The impulse of the car!
Finally, the carbon deposit in the engine's combustion chamber will cause cylinder knocking, causing damage to the piston and crankshaft, which will seriously affect the safety of the car, and the emission of the car will exceed the standard. This will not only pass the annual inspection, but also directly increase the pollution environment. Hazard. If it is serious, the valve will not be closed tightly, so that there is no cylinder pressure in the cylinder and it will not work at all, and even the valve will not stick back. At this point, the valve and the piston will have motion interference, which will eventually damage the engine.
