Anglu Xiaobian:

The timing belt is located between the camshaft and the crankshaft of the car. Don't look at it as a belt. Its main purpose is to ensure that the valve and piston run with each other. During the entire engine operation, the most important operation is the crankshaft. All timing It is based on the rotation angle of the crankshaft, so it is an important part to ensure the normal operation of the engine.

When the timing belt fails or breaks directly, the valve and ignition work will be disordered or stopped. In severe cases, the valve may even be broken and the piston may be pushed through, requiring major repairs.

In addition to normal aging and wear, the reasons for the damage of the timing belt include problems with the operation of the tensioner, idler, and guide wheels, some external pollution or damage, incorrect installation, etc., including the following three reasons, which will also cause the timing The belt fails or breaks.

  • Belt installation tension setting error:When the timing belt is installed, if the tension is set too high or too low, it may cause breakage.

  • Excessive impact load:When the intermittent or periodic torque load required by the driven equipment is greater than the normal level, this impact load will exceed the force that the belt itself can withstand, which will often aggravate the fracture and failure of the belt.

  • Corrosion air, foreign matter:If the timing belt is working in a corrosive air environment for a long time or in an environment with poor air quality, it will also cause the belt to wear faster.

Of course, taking into account the actual situation of the car, may be due to a variety of factors, resulting in the replacement of timing parts in advance. This requires us to always self-check when driving!
