Ancient horses have cars, and vehicles are evolving with the development of society. Today's young people are basically car owners. As we all know, a car is composed of thousands of parts, and the engine is the core component of the car, each structure is very fine, and each screw plays an extremely important role in the entire engine and even the entire car.

In the engine, there is a more common component, that is, the engine timing system. At present, the timing system is divided into two types: belt drive and chain drive. Many car owners do not understand which is better, timing belt or timing chain. Today, the editor will continue to explain to you the secrets that have to be said about car belts.

Timing belt VS timing chain

Nowadays, more and more cars use timing chains. Its benefits are as advertised by the manufacturers. It is maintenance-free for life and basically there is no risk of breakage. But the disadvantage isThe manufacturing cost is high and the noise will be greater.After all, there is contact between metals. When the total mileage of the car reached 100,000 kilometers, the shortcomings of the timing chain began to appear.

Beautiful before 100,000, eldest mother after 100,000.At this time, the friction between the timing chain and the transmission wheel is getting more and more serious, and you can clearly hear the metal friction sound from the engine compartment. If you want to replace the timing chain, you will save money for 100,000 kilometers, and you will have to build some in. Another problem is that the chain needs lubrication, so there are certainOil leakageRisk.

In comparison, the timing belt is much more affordable. The sound of friction between rubber products and metal is very small, and after passing through the sound insulation layer of the engine compartment, the noise can be ignored. In addition, the friction between rubber products and metal is relatively small, so the transmission resistance of the belt is also small, which can ensure the normal power output and acceleration performance of the engine.

But it should be noted that we should also take good care of our hands and feet. Bad habits such as frequent rapid acceleration and high-speed shifting will affect the service life of the belt. Once the timing belt is damaged, the valve and ignition work will stop, and the engine will not work, so we must replace it regularly.

Timing belt replacement time

For different models, there may be differences, mainly depending on the maintenance items in your maintenance manual and the replacement cycle. Generally, the original factory is more durable, and the first replacement can basically reach 10-150000 kilometers. The 4S store is usually in60% of the maintenance periodIf you are asked to replace it, for example, if the maintenance cycle is 150000, it will probably tell you that you need to replace it from 8 to 90000. After all, others do not know the purpose of your vehicle.

If your car is long-termempty car running, can be checked at 100000 kilometers, no problem continue to use, 13-150000 replacement; If oftenload bearingIf the damage to the belt is large, check it at 6-80000 and replace it 100000; ifhas been replaced, then re-inspection and replacement should be 20000 kilometers in advance.
