Whether the chain or belt used for the engine timing mechanism is reliable Each has its own characte

Comparison of the advantages and disadvantages of timing belts and timing chains.

Compared with the traditional belt drive, the chain drive is reliable, durable, and space-saving, the system is composed of gears, chains and tensioning devices, etc., and its hydraulic tensioner can automatically adjust the tension force, so that the chain tension is consistent, and it is maintenance-free for life. Superior durability allows the system to last as long as the engine.

The main function of the timing belt is to drive the valve mechanism of the engine, so that the intake and exhaust valves of the engine can be opened or closed at the appropriate time, so as to ensure that the cylinder of the engine can be inhaled and exhausted normally. In some models, the timing belt is also responsible for driving the water pump, such as the Jetta EFI, Santana 2000, Bora, Audi and other models in the Volkswagen models.

For all engines, the timing belt is absolutely not allowed to jump teeth or break, if once the gear jumping phenomenon occurs, the engine can not work normally, there will be unstable idling, poor acceleration or not on the car; If the timing belt breaks, the engine will stop immediately, and multi-valve engines will also cause the piston to bend the top valve, which can seriously damage the engine.

Timing belts belong to rubber parts, and with the increase of engine working time, timing belts and timing belt accessories, such as timing belt tensioners, timing belt tensioners and water pumps, will wear or age. Therefore, where the engine is equipped with a timing belt, the manufacturer will have strict requirements, in the specified cycle to replace the timing belt and accessories regularly, the replacement cycle is different with the structure of the engine, generally in the vehicle to 60,000 100,000 kilometers should be replaced, the specific replacement cycle should be subject to the vehicle's maintenance manual.

The timing of the engine is either a belt or a chain. Timing belt and timing chain, these two accessories are completely different from the material, one is a belt, is rubber, and the other is a chain, is metal.

The inside of the timing belt has a number of rubber teeth, which cooperate with the grooves of the corresponding rotating parts on the outside of the engine to drive the other parts to rotate synchronously as the crankshaft rotates. The advantage of timing belts is that they are less noisy; Low resistance; The transmission inertia is small; Easy to replace; Low maintenance costs; The power transmission and acceleration performance are better.

Since the main material of the timing belt is rubber, which makes it very elastic, the timing belt can achieve a perfect fit with the gear, and realize the accuracy of the engine piston movement and the opening and closing of the intake and exhaust valves.

Hello! Engine timing belts and timing chains are important transmission components of the engine, and their role is to ensure the synchronous movement between various parts of the engine to ensure the normal operation of the engine. The main differences between them are aspects such as material, service life, and noise.

1.Materials: Timing chains usually consist of metal links and plastic guides, while timing belts are made up of rubber and fibers.

2.Service life: The service life of the absolute timing chain is relatively long, generally can reach more than 100,000 kilometers, but with macro knowledge is the need for regular inspection and replacement.

The service life of timing belts is generally about 60,000 kilometers, and it is more susceptible to high temperatures and grease.

3.Noise: The transmission noise of the timing chain is comparatively small, whereas the transmission noise of the timing belt is comparatively large.

In general, timing chains have a long service life and low noise, but they need to be checked and replaced regularly; Timing belts are relatively inexpensive, but have a shorter lifespan, are more susceptible to heat and grease, and are noisy. The choice of which transmission form to use needs to be decided according to the specific model and use case.

Whether the engine timing is a good chain or a belt has its own advantages and disadvantages, according to the needs of the ear.

The advantages and disadvantages of timing belts and timing chains are divided into three aspects: 1. Advantages and disadvantages of manufacturers 1. There is no doubt that the use of timing belts can reduce costs, otherwise it will increase costs; 2. The use of timing belt manufacturers can continue to benefit in the later use (** leather brother trapped belt to earn profits); 3. The timing belt is used to improve the power of the engine (explained in the advantages and disadvantages of the belt chain). Second, the user's advantages and disadvantages 1, the use of the timing belt of the engine will increase the user follow-up car maintenance costs, on the contrary, the chain does not need to pay this fee (within 30w kilometers) 2, the timing belt due to the service life, if the replacement is not timely, it will lead to the car breakdown; 3. Advantages and disadvantages of timing belts and chains 1. Advantages of belts:

Low belt noise; The belt transmission resistance is small, and the transmission inertia is also small, which can improve the power and acceleration performance of the engine, and the belt is easy to replace. 2. The shortcomings of the belt are easy to age, and the failure rate is high; 3. The advantages of the chain have a long service life (no need to replace within 30w kilometers) The failure rate is low, and it is not easy to cause the car to break down due to timing transmission failure 4. The shortcomings of the chain The chain rotates with high noise; The chain drive resistance is large, and the transmission inertia is also large, which increases fuel consumption and reduces performance from a certain angle.

1. In the past, most engines were driven by belts, this is because the belt has the characteristics of low noise, low cost and simple maintenance, but the disadvantage is that the life of the belt is relatively short, generally 3-4 years or about 6-80,000 kilometers need to be replaced once, and it needs to be replaced on time.

2. If the formal belt is broken, due to inertia, the crankshaft and camshaft will continue to rotate, but there is no belt connection between them, and they are in free rotation, when the valve is opened, the piston also happens to move to the upper fulcrum, and the two hit each other, the valve will be bent, the top of the piston will also be injured, and the serious connecting rod will also be deformed. If you need to overhaul the engine, it will be expensive;

3. The timing chain is made of alloy material, inside the engine, organic oil lubrication, and the service life can theoretically be scrapped until the car, but the chain "tensioner" only has a wear life of 8.1 million kilometers, and the time is up to replace, and the replacement of the tensioner is basically only one-tenth of the timing belt;

4. The timing chain is a kind of engine timing belt, their main role is to drive the engine's valve mechanism, the upper connection is the timing wheel of the engine cylinder head, and the lower connection is the crankshaft timing wheel, so that the engine intake valve and exhaust valve can be opened or closed at the appropriate time to ensure that the engine cylinder can be suction and exhaust normally. Both the chain and the belt serve the same purpose. It can be said that the chain is a "variant" of the belt.

In recent years, there are many models used, and the advantage of timing chain is that it has a long service life and can basically be maintenance-free, but it is not absolute;

5. The so-called maintenance-free is within a certain extent, not that it does not need to be replaced, if the chain and the guide plate are too worn, they also need to be repaired and replaced, and because the chain tensioner is provided by the oil pressure, if the oil pressure is insufficient, it may cause engine damage, and the disadvantage of the chain is that the noise is slightly louder, and it is more troublesome to maintain, and the cost is very high;

6. From the current engine technology trend, it is inclined to use the chain, because the chain is indeed much more durable, once the belt forgets to replace, there is a problem, that is, the valve is bent, the maintenance cost is very high, generally tens of thousands, so it is recommended that friends if the car uses the timing belt, must be changed on time, do not feel that it can be used.

Hello! 1.Timing belts:

1) Advantages: relatively low, low noise, low transmission resistance, good engine dynamics and acceleration performance, easy to replace, etc.;

2）.The disadvantage is that it is easy to age, the failure rate is relatively high, and the maintenance cost is high.

2.Timing chain:

1）.Advantages: long service life, low failure rate;

2）.Disadvantages: high turning noise, slightly increased fuel consumption, and reduced performance. Of course, with the improvement of technology, the shortcomings of timing chains are slowly improving, and according to the current development trend, timing chains will also be used more.

The difference between the two: the timing belt is very taboo about oil pollution, and after a long time, it will break, and the damage to the engine will be relatively large; Timing chains, which require good lubrication (oil splash lubrication), will hardly break, but the sealing requirements for timing covers are relatively high. Each has its own advantages and disadvantages, but it is necessary to refer to the vehicle manual regularly to do relevant maintenance of the timing belt or chain.

The service life of the chain is long.

First of all, the timing system controls the opening and closing time of the valve to ensure that each cylinder is exactly right, and when the piston compresses upwards and approaches the top dead center, the spark plug ignites, igniting the oil-gas mixture, and realizing the work of the engine. The main material of the timing belt is rubber, which is a consumable. It wears out gradually with mileage and years until it breaks.

If the timing belt breaks, the valve system cannot operate according to the engine's operating conditions, resulting in errors. Open the valve at the same time, at this time the valve is likely to collide directly with the top of the piston, and the valve may bend or even destroy the piston, causing very serious consequences.

Secondly, the role of the timing chain can well drive the engine to work effectively. The noise is relatively loud, but it has little impact in the car, and it is basically inaudible. In addition, the development of technology has produced a "toothed silent chain", which can be said to be less noisy than a belt, so there is no need to worry about the noise of the chain being much better than the belt, and the utilization rate of the chain is steadily increasing.

In timing systems, the transmission components used to connect the crankshaft and the valve system often play an extremely important role. This transmission component connects the engine to the intake and exhaust camshafts, transmitting the force to the distributor through the drive of the crankshaft.

The second is that timing belts have been used in engines for a long time, with mature technology, low cost and low noise. However, it needs to be checked and maintained regularly, and it generally needs to be replaced every 50,000 to 100,000 kilometers. The timing chain has significant advantages such as compact structure, high transmission power, high reliability and wear resistance, and maintenance-free for life.

However, they are generally slightly noisier than conventional timing belts. If you can't determine the timing belt replacement cycle, you can refer to the maintenance interval specified by the car manufacturer. The maintenance cycle stipulated by different car manufacturers is not exactly the same, and the specific replacement cycle is subject to the requirements of the car manufacturer.

Finally, the material of the timing belt is indeed not as strong and wear-resistant as the timing chain, but its technology is mature, the popularity rate is high, and the mute effect is also very good. TomatoIn contrast, most models with timing chains have largely overcome the so-called wear and tear of 100,000 km, but with the added effect of increased dynamic noise and the need for regular adjustments. Timing belts and timing chains are indistinguishable from each other.
