Engine jumping teeth (engine jumping teeth): How to deal with it?import export database The car engine is one of the important parts of the car. Its main task is to mix fuel and air, burn it, and convert it into power to drive the vehicle.One of the well-known parts of the engine is the timing system. The timing system is mainly responsible for controlling the relative position and time of the valve and piston, so as to ensure the normal operation of the engine. However, during the high-speed operation of the engine, sometimes there will be a problem of engine jumping teeth (engine jumping teeth), which will have a serious impact on the operation of the engine. This article will introduce how to deal with this problem. What is the reason for the engine jump (engine jump)? First of all, we need to understand what engine jump teeth are (engine jump teeth). Engine jump teeth (engine jump teeth) refers to the loosening of the engine timing chain or timing belt caused by high-speed driving or insufficient oil and other reasons. The loosening of the timing chain or timing belt will cause the valve to lose sync with the piston, which will cause the engine to shake or even stop. There are many reasons for engine jumping teeth (engine jumping teeth), some of the main reasons include the following points: 1.Timing belt or timing chain aging and wear Timing belt or timing chain will be subject to friction loss and aging for a long time, so it will lose its elasticity and no longer have stability. This means that in high-speed operation or in low-temperature and high-humidity environments, the timing belt or timing chain may jump due to loss of strength. Two. Faults between the timing wheel and the timing belt or timing chain. The fault between the timing wheel and the timing belt or timing chain can also cause the engine to jump. For example, if the timing belt or timing chain is damaged, too much loosening will occur, which will cause the timing wheel to slide to a position out of sync with the piston, causing the engine to jump. 3. Excessive wear of friction materials. Excessive wear of friction materials may also cause engine teeth to jump. For example, the friction material wears out when there is too little oil, resulting in the timing chain or timing belt to jump.Four. If the motor loosens other parts of the engine, such as the motor, loses stability, it will affect the timing synchronization of the engine, resulting in problems such as engine jumping teeth. 5. Wrong maintenance. Wrong maintenance may also cause the engine to jump. If the number of meters of the timing belt or timing chain does not match the requirements of the transcription cycle, or the hydraulic tensioner, steering pump and other parts are not replaced in time after replacing the new timing belt or timing chain. These unreasonable maintenance measures may cause engine gear failure. How to deal with engine tooth jumping (engine tooth jumping)? What action should we take when we encounter the problem of engine jumping teeth? First of all, you need to drive the vehicle into a safe parking lot or roadside and turn off the engine. At this time, the vehicle needs to be sent to a professional repair station for maintenance. If you have rich mechanical knowledge and enough experience, you can handle such problems by yourself.The following are some ways to deal with engine jumping teeth (engine jumping teeth): 1. Check the timing belt or timing chain. Check whether the tension of the timing belt or timing chain is correct, especially during the warranty period of the new car. For example, the 1.8L Qichen R50 new car needs to be replaced at the 3000-kilometer checkpoint. If the timing belt or timing chain is worn or cracked, it needs to be replaced in time. Two. Check the lines of the timing belt and timing chain. The timing belt or timing chain should not be cracked and worn. The grain should be clear. 3. Check the regulator of the timing belt or timing chain. The adjuster of the timing belt or timing chain also needs to be continuously checked. If the timing belt or timing chain is not tightened, it is easy to have the problem of jumping teeth. Four. Replace the vehicle's oil. If there is too little oil, there will be a problem of engine jumping teeth. Therefore, the comparative solution is to replace the engine oil of the vehicle in time.In a word, engine jump (engine jump) is a common car failure. In order to reduce the possibility of engine jumps, we can maintain it every six months or 5,000 kilometers. If there is a problem with tooth jumps, notify the car repair station immediately to solve the problem. Dealing with the problem of engine jump gear as soon as possible can make the engine more stable and reliable, ensuring normal driving and low maintenance costs.
