As a core component of the engine, we often ignore when maintaining or buying a car, that is, the engine is the toothed belt, according to the function of the connection with the crankshaft and with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. The timing toothed belt of the car plays an irreplaceable and important role in the interior of the car, and the transmission belt on the car is responsible for driving the movement of all parts, and it cannot move when the car is broken. According to the structure of the vehicle engine, the current engine is equipped with timing toothed belts are divided into belts and chains.
This one can be said to have its own merits! It has its own characteristics, but from the big picture of the timing chain and belt, the performance of the chain far exceeds the belt, from the cost and other aspects of the analysis, the engine mounted timing belt in the transmission mechanism is relatively simple, under the effect of the belt, the noise of the belt is much smaller. However, depending on the material, it needs to be replaced regularly, and the maintenance cost is high.
The belt kit needs to be replaced regularly, the belt must be replaced from 5-8w km, once there is no timely maintenance and replacement, once the belt is broken, it will lead to the piston top valve of the engine, the gain outweighs the loss.
Although the chain drive is more complex in structure, due to the low follow-up maintenance cost of the chain due to its own material and structure, it can basically be said to be maintenance-free. Even if it is damaged during use, the maintenance cost in the later stage is lower, and the maintenance and replacement should be simple, which can accurately ensure the valve timing of the engine.
With the continuous progress of the engine's technical level and industrial development, the timing belt of some engines has been replaced by the engine chain, compared with the traditional belt drive, the transmission of the chain drive mode is reliable, the durability is good and can also save space, from the current development trend of engine technology, they prefer to use the chain, after all, the durability of the chain is very strong.

What is the difference between a car engine timing belt and a timing chain? This tells you, car owners: teachable!
The engine of a sedan is the heart of a sedan. Therefore, the transmission belt of the engine is particularly important. Timing belt I believe most drivers have heard of it, once the timing belt breaks, the light will be the top valve, and the whole engine will be wasted.
However, there are also some vehicles that use timing chains, so some netizens have questions, which is better, timing belt or timing chain? What is the difference between the two?
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 used for 3-4 years or about 6-80,000 kilometers and needs to be replaced once, and it needs to be replaced on time.
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 when they rotate freely, there will be 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 up, the top of the piston will also be injured, and the serious connecting rod will also be deformed. If you need to repair it, you need to overhaul the engine, which is expensive.
The timing chain is an alloy material, inside the engine, organic oil lubrication, and the service life can theoretically be scrapped to the car, but the chain "tensioner" has only 8 100,000 kilometers of wear life, and the time is up to replace, and the replacement of the tensioner is basically only one-tenth of the timing belt.
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 are 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 life and can basically be maintenance-free, but it is not absolute.
The so-called maintenance-free is within a certain extent, not that there is no need to replace, if the chain and the chain guide plate wear too much, it also needs to be repaired and replaced, and because the chain tensioner is dependent on the oil pressure to provide tension, if the oil pressure is insufficient, it may cause engine damage, the disadvantage of the chain is that the noise is slightly louder, and the maintenance is more troublesome, and the cost is very high.
From the current engine technology trend, are 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 replaced on time, do not feel that it can be used.
-
The difference is the material, the belt is generally made of neoprene, while the chain is generally made of steel, I think the chain is better because of the long life.
-
I think timing chains are better because the chains are made of steel, while the belts are made of rubber.

Hope it helps.
Infiniti QX50, that one is a belt, or a timing chain of the chain.
How about the fuel consumption of this car, the fuel consumption is usually high, but the fuel consumption performance of the variable compression ratio engine it is equipped with is still very good under complex working conditions.
It's that engine, thank you.
The comprehensive fuel consumption is generally about 12L, and the stability of this car is relatively good, so you can choose.
Is its four-wheel drive ability good, and is there something wrong with love?
It's not bad, especially for family cars, this is completely enough, and it's not a big problem to maintain it well. But it can't be used as an off-road vehicle.

Answer: Whether the timing of the engine is 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. The timing belt is generally made of rubber, and it will wear or age with the increase of the engine's working time, so the engine generally equipped with the timing belt needs to be replaced after a certain cycle.
For all engines, timing belts must never skip or break. If the gear jumping phenomenon occurs, the engine will not work normally, and there will be unstable idling, poor acceleration or inability to hit the car; If the timing belt breaks, the engine will stop immediately, and the multi-valve engine will also cause the piston to bend the top valve, which will seriously lead to the direct scrapping of the engine.
During the working process of the engine, the intake and exhaust valves need to be opened in a timely manner, and the engine crankshaft timing gear transmits power to the timing gear of the camshaft, and the power transmission is required between the two timing gears, and the timing chain is one of the transmission modes.
The timing chain is usually made of alloy material, and inside the engine, the organic oil lubrication, and the service life can theoretically be scrapped until the car is scrapped, but there will be wear, stretching, etc.; In addition to being stretched, timing belts also have a risk of breakage, problems, and more damage to the engine.
Some models, about 10-120,000 kilometers need to replace the timing chain, and some models are maintenance-free for life (see model maintenance manual for details); However, in fact, the chain tensioner also has a normal wear and tear life, and the time is almost to check and replace, and the parts of the tensioner are naturally very small compared to the belt kit when changing the alignment.

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, in free rotation, there will be when the valve is opened, the piston also just moves to the upper fulcrum, 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, and the engine will need to be overhauled if it is repaired. However, the chain, tensioner, only 8,100,000 kilometers of wear life, time to replace it, tensioner replacement ** is basically only one-tenth of the timing belt.
-
The timing chain is different from the timing belt in terms of material, which is the chain microalloy material, lubricated by organic oil inside the engine, and the service life can theoretically be used to scrap the car, but the tensioner of the chain has only 8 to 100,000 kilometers of wear life, and when the time comes, it must be replaced, and the purchase of the tensioner is basically only one-tenth of the timing belt.
-
The energy consumed by the rotation of the machine driven by the belt is relatively large, and the power required for the belt to make the engine work is also relatively large, and the use of the chain can relatively reduce a certain amount of energy consumption, so that the work efficiency is improved, and the additional loss is greatly reduced.
-
The belt needs to be maintained, and it must be replaced for 6-80,000 kilometers, otherwise there is a risk of belt breakage leading to the top valve. The timing chain, on the other hand, is maintenance-free and has engine oil lubrication to reduce wear and extend life.

What are the advantages and disadvantages of using chains and belts in the engine? Today is a long time to see.

The timing belt is an important part of the engine valve system, which ensures the accuracy of the intake and exhaust times through the connection with the crankshaft and a certain transmission ratio. The belt is used instead of the gear for transmission because the belt is quiet, the transmission is accurate, the amount of self-variation is small and easy to compensate. Obviously, the life of the belt is definitely shorter than that of metal gears, so it is necessary to replace the belt regularly.
The function of the timing belt is that when the engine is running, the piston stroke (up and down movement), the opening and closing of the valve (time), the sequence of ignition (time), and the "timing"."to keep "synchronous" at all times.
Timing, that is, through the timing mechanism of the engine, so that each cylinder is just right: when the piston is up to the top dead center, the valve is just closed, and the spark plug is just ignited.
The timing belt is a consumable product, and once the timing belt is broken, of course, the camshaft will not run according to the timing, which is very likely to cause serious damage due to the collision between the valve and the piston, so the timing belt must be replaced according to the mileage or time specified by the original factory.
In the working process of the automobile engine, four processes of air intake, compression, exhaust and exhaust continue to occur in the cylinder, and the timing of each step should be matched with the movement state and position of the piston, so that the intake and exhaust and piston lifting are coordinated with each other, and the timing belt plays a "bridge" role in the engine, and the force is transmitted to the corresponding parts under the drive of the crankshaft. In order to ensure the stable operation of the timing system, many high-end cars use metal chains instead of belts. Because the internal valve of the engine will be damaged after the timing tooth belt of the vehicle is broken, which is more harmful, the general manufacturer stipulates a replacement cycle for the timing belt.
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.

To drive the east belt, some cars have one, and some have two separate belts such as water pump belts or air conditioning pump belts. Then there's the timing belt, but most cars now have timing chains. Timing belts, power pump belts are important.

This general belt is the belt of the generator and the belt of the compressor. If the belt of the generator is broken, the generator will not generate electricity, which will cause your battery light to turn on, and the car will not start directly.

Glad for the question! Whether it is the engine belt (the belt here should be the timing belt) transmission is good or the chain drive is good, this can be said to have its own merits! Each has its pros and cons!
1.Timing belt: Timing belt drive can be said to be used by most old cars!
Advantages: mature technology, low maintenance cost, easy maintenance! Low noise!
Disadvantages: short service life, every 80,000 km or 60,000 km must be replaced! It's a pity that after the break, the consequences are quite serious.
Timing belt breakage can lead to valve and piston jacking, valve bending, piston bending, and even engine scrap! So the consequences are serious, and the cost of repairs will be **! 2.
Timing chain: Now many ** are timing chains, of course, there are also some family shirts. For example, the Volkswagen Jetta model is a timing belt.
Its biggest advantage is that it has a long service life, which is two or three times longer than that of a timing belt. Generally, it will not be broken directly. If there is a problem, only the chain is stretched or the fault light is on, basically there will be no jumping or broken teeth!
If an engine failure reports a timing delay or an intake and exhaust camshaft too early, if there is no problem with the actuator, it could be a timing issue! Its disadvantages are also obvious: it is noisy and there will be a rattle!
The cost is high and the maintenance is too troublesome! Zhaocao summary: If you have to say which one is better, I think the chain is better.
After all, it was timing chains that eliminated timing belts a few years ago. Now that the elimination has become a fact, it shows that the chain is definitely stronger than the belt! In terms of the service life of the chain annihilation mountain, it is also very desirable, but the noise is relatively loud and can be completely ignored!
Sometimes it's easy to forget to change the timing belt and cause big problems!
An engine is a complex machine that consists of many mechanisms and systems. Whether it is a gasoline engine, or a diesel engine; Whether it's a four-stroke engine or a two-stroke engine; Whether it's a single-cylinder engine, or a multi-cylinder engine. In order to complete the energy conversion, realize the work cycle, and ensure the continuous normal operation for a long time, the following mechanisms and systems must be in place. >>>More

The T-72 tank, for example, used a 780-horsepower V12 diesel turbocharged engine, which was officially installed in 1939. In many technologies, it is no different from the current diesel engine, and it also adopts a water-cooled heat dissipation system, which is completely consistent with the civilian diesel engine. Of course, given the age of development of this engine, it does not have the high-pressure common rail fuel supply system found in today's diesel engines, but instead uses a mechanical fuel supply system that is not easily damaged and easy to repair. >>>More
The biggest advantage of the direct injection design of the fuel supply system is that the fuel is directly injected into the combustion chamber at a very high pressure, so in addition to the structure and position of the fuel injector are different from the traditional oil supply system, the atomization and mixing efficiency of oil and gas is also more excellent. Compared to the 6-cylinder and 4-cylinder cars, the 6-cylinder car works more stably, and if there are two cars in the same price range, such as the Teana and the Accord, I personally recommend that you consider the Nissan Teana first, the Teana is more cost-effective. >>>More
