Time belt connects the crankshaft gear, the bond of the camshaft gear, it is an important part of the engine ignition. Ensure the opening time of the inlet, the piston runs up and down, and the fuel injection time is performed according to the engine work requirements to ensure the normal operation of the engine.
Time belt is rubber products, so it will also be damaged. When the positive belt is broken, it will cause major losses of the engine. It will cause damage to the valve, piston, connecting rod, even hijab, and cylinder. Therefore, the manufacturers require regularly replace the timing belt.
Some people say that the manufacturer stipulates that the timing belt is replaced at 6_8,000 kilometers, and my car driving more than 100,000 kilometers is also good. Then I tell you, you are lucky. Some people just do not change the time when the belt causes the vehicle to break down, and the loss is great.
There is such a friend around me. The vehicle is close to 100,000 kilometers. It was originally ready to change the time belt, but that day was just going to run on the long distance. Sudden time on the highway was broken, it was not done. Less money.
Because the timing belt is a rubber product, it will also age, stretch, crack, wear, peel, and other phenomena. When this phenomenon appears in the right time, the engine often has some signs, but it is relatively mild. The car is relatively mild. Friends did not pay attention, and it may be caused by other reasons. For example, the soil door is dirty and the engine shakes, and the regular belt failure can also cause engine jitter. In the case, there is no positive belt on the heart.
What are the signs before the tactical belt failure?
1. If the time tape is stretched, the engine ignition time will become late, the idle speed shakes, the refueling is not smooth, the hair is stuffy, and the exhaust pipe may have gray smoke discharged. In severe cases, it is easy to turn off.
2. If the time the time belt is too abrasion, the sound of the front end of the engine is noisy.
3. The sound of the feet in the exhaust valve increases.
4. The engine of the engine has a recovery sound of Bufu.
In fact, we can check the timing belt ourselves. Open the upper cover on the outside of the time, you can find that there is the following situation and must be replaced.
1. The belt is obviously aging and has a small turtle crack.
2. There are cracks in the inside of the belt.
3, the belt starts.
4, belt teeth wear.
5, wear on both sides of the belt (expose the wire layer).
6. Other situations.
Time belts are the key position of whether the engine works, and it is mostly sudden. Therefore, it is necessary to replace regularly.
