How does the new Regal clean up carbon deposits?

If the carbon deposit is not serious, there is no need to clean it up for the time being. If the vehicle is used in urban areas for a long time, it is recommended to clean the fuel injector and air intake every 20,000 km and the electronic throttle body every 654.38+00,000 km. If the vehicle has very good road conditions and drives at high speed for a long time, the cleaning cycle can be extended. Harm of carbon deposition

1. When carbon deposits are attached to the exhaust valve, the intake valve and exhaust valve are not tightly closed, resulting in air leakage and pressure drop in the engine cylinder. The direct result is that the engine is difficult to start and jitter occurs at idle speed; At the same time, it affects the cross section of the mixture entering the combustion chamber, and the carbon deposit can adsorb a certain mixture, thus reducing the engine power. 2. When the carbon deposits are attached to the cylinder and piston crown, the volume (space) of the combustion chamber will decrease and the compression ratio of the cylinder will increase. If the compression ratio is too high, the engine will burn ahead of time (the engine will knock) and the power of the engine will be reduced. 3. The carbon deposit attached to the spark plug will affect the spark quality; Don't even jump on fire. When carbon deposits are formed between piston rings, the piston rings are easily stuck, resulting in deformation of oil and cylinder wall. 5. When the carbon deposit is attached to the oxygen sensor, the oxygen sensor can't correctly sense the exhaust condition and adjust the air-fuel ratio, which leads to the engine exhaust exceeding the standard. 6. When carbon deposits are formed in the intake manifold, the interior will become rough, thus affecting the formation and concentration of combustible mixture. Prevent carbon deposition

The diagnosis of carbon deposit is always a difficult problem in automobile maintenance. It is even more difficult for car owners to identify whether there is carbon deposition. It is best to nip in the bud and maintain the normal use of vehicles through daily maintenance. The following are several ways to reduce and prevent carbon deposition. 1. Fill with high-quality gasoline. Impurities such as wax and colloid in gasoline are the main components of carbon deposition, so the carbon deposition trend of high cleanliness gasoline is weak. Unfortunately, at present, the quality of gasoline in China is still low compared with that in developed countries, so we can only briefly talk about it. It should be noted that high grade does not mean high quality, that is to say, 97 # oil is not necessarily less than 93 # oil, and grade only represents the octane number of the oil, not the quality and cleanliness. In order to ensure the cleanliness of gasoline, some car owners will adopt the practice of adding gasoline detergent to gasoline. This can effectively prevent the formation of carbon layer on metal surface, and gradually activate the original carbon particles to be removed slowly, thus protecting the engine from damage. However, the addition of gasoline detergent must be cautious. If counterfeit and shoddy products are added, it will have the opposite effect. 2. Don't be idle for a long time.

The longer the idle time, the longer it takes for the engine to reach normal temperature, the slower the evaporation rate of gasoline sprayed on the back of the valve, and the carbon deposition will also occur. At the same time, often idling, the air flow into the engine is also small, so the scouring effect on carbon deposits becomes weak, which will promote the deposition of carbon deposits. 3, run more high speed, try to improve the shift speed of the walking car. The purpose of high-speed operation is to prevent carbon deposition by using the scouring effect of airflow on the inlet. In addition, improving the speed of shifting gears has the same effect as running at high speed. Changing the shift from 2000 to 2500 can not only effectively prevent carbon deposition, but also improve efficiency.
