What is the clicking sound of 20 19 Sylphy engine?
When idling, the engine makes abnormal noise, which is the sound of knocking on the cylinder, so there will be jitter. Just clean up the oil circuit. It's not a big problem. This low-speed and post-braking jitter is related to the oil circuit and belongs to low-speed jitter or idle jitter. Which parts can't be checked out, in fact, there is really no problem. As long as they are cleaned with Siyoupu fuel cleaner, the jitter will disappear completely. The main reason is that there is too much water and gum in the oil impurities, which may not be caused by your car, and it is also related to the fact that the gas station did not clean the fuel tank. The gas station must clean the fuel tank once in1-February.
Engine noise is getting louder and louder because of too much carbon deposit, which is probably caused by too much carbon deposit at first. Because many cities are very congested now, it is inevitable to have some bad driving habits when driving to and from work. In the long run, the engine will produce a lot of carbon deposits due to long-term low-speed operation, which will lead to increased engine noise. Secondly, many people covet cheapness and add some cheap oil. There are many impurities in these oils, and the quality cannot be guaranteed, forming a large amount of carbon deposits. With the continuous accumulation of carbon deposits, the engine will shake, the power will drop and the noise will become louder and louder. Therefore, if you drive on the congested road in the city for a long time, it is recommended to run at high speed regularly, so that a large part of the carbon deposit will be blown out of the cylinder or the carbon deposit in the engine will be cleaned regularly. Also, when you refuel, try not to go to a gas station where you can't guarantee oil products because of petty advantages. It is recommended to go to large regular gas stations such as PetroChina or Sinopec to refuel.
