The engine belt is the most important belt in the car, connecting the generator, air conditioning compressor, booster pump, idler pulley, tensioner pulley, crankshaft pulley, etc. Its power source is the crankshaft pulley, and the power is provided by the rotation of the crankshaft. If it fails, the generator will not be able to produce electricity, the booster pump will fail, and the steering will not turn. very dangerous situation. The motor belt must therefore be replaced regularly.
For example, if there is a problem with the brakes, obviously we can feel that the brake pedal is slow and the engine temperature is too high, then the reason may be that the reservoir of water lack of water. Although today, with the development of automotive technology, with driving computers and sensors, if there is a problem with the car, many situations arise.will appear in our dashboard lights and the root cause will be reported.
However, although many problems can be detected by sensors and reflected on the dashboard, there are still some problems that cannot be detected by sensors and require more advanced automotive technology. At this time, the car owner needs to find out the precursors and use the car precursors to determine the vehicle problem, which requires hard work from the car owner. The three main parts that cause the most problems with cars, and the ones that often have problems among the three main parts, are the transmission and the engine. If the transmission uses a manual transmission, the likelihood of problems is low, and there are many of them. types of problems with the engine. Among them, the sensor is prone to problems. What cannot be detected,It's the timing belt.
What is a timing belt? “The timing belt is an important part of the automobile engine's gas distribution system. It is connected to the crankshaft and associated with a certain transmission ratio to ensure the accuracy of intake and exhaust timings. Since the timing belt is a rubber product and has a certain service life, it is necessary to check the engine timing belt regularly depending on the make and model of the car, and determine whether it needs be replaced according to the inspection situation. The crankshaft and camshaft are connected by the upper toothed groove. ?The reason the timing belt is more likely to have problems is because it is made of rubber. When the engine warms up and then stops, the temperature drops suddenly. Because the temperature difference istoo much, the rubber material is easily oxidized. If things continue like this, the timing belt will age. Therefore, car owners should regularly check and replace the timing belt. Generally, the original timing belt should be checked and replaced when the car owner drives 60,000 to 80,000 kilometers. This value also varies depending on the driver's usage habits. the car owner is really worried, he can start the inspection at 50,000 kilometers.
The timing belt is an essential element of the engine and one of the guarantees of normal engine operation. If the timing belt breaks, the consequences will be very serious. At a minimum, the movement of the engine piston will be chaotic, the spark plug firing and air intake will not match, and in the worst case the engine will be scrapped. Consequentlyent, car owners should be careful. When these conditions occur in the car, it is a sign that the timing belt needs to be replaced.
If when we drive, we feel that the driving is unstable, the accelerator is not smooth, and the car shakes often, the car owner should pay attention to it. One of the reasons why this happens in vehicles is that the engine has heavy carbon deposits, and the other is that there is a problem with the timing belt. At that time, the car owner should pay attention and send it for inspection. If the car owner hears an obvious abnormal sound of metal collision in the engine compartment while driving, the car owner will stop immediately and ask a tow truck to be towed for repair, because the timing belt is is broken at this timehas. is caused by errors in the opening and closing times of the valves.
Everyone who is familiar with automobile repair knows that the engine mainly works according to the four processes of intake, compression, explosion and exhaust in the cylinder. The timing of each step must be related to the motion state and position of the cylinder. The piston cooperates with each other to coordinate intake and exhaust as well as piston lift. In this process, the timing belt actually plays the role of a bridge. It uses the engine's timing mechanism so that each cylinder has the piston exactly up. , just right. At top dead center, the valve is just closed and the spark plug lights.
The reason why a belt is used instead of a gear is that the belt has a precise and low noise transmission and its own changes are easy to compensate. However, the wrathie distribution is a rubber product and is. It is also a consumable product, so it must be replaced regularly.
Someone must have asked at this time, how long does it usually take to replace it? Generally, the replacement time depending on the brand is different. Strictly follow the car owner's manual and replace it in time. However, it is generally recommended to replace it before the replacement time is near, which is safer and more reliable. ?If you find that the engine is making an abnormal noise, you should check it regularly to see if the timing belt needs to be replaced. Experienced drivers can make an estimate based on time or kilometers, which is about 80,000 to 100,000 kilometers, or use 3. -Regular maintenance is required every 4 years, and the timing belt should be replaced in time.
The most important thingst that if the timing belt is not replaced in time, causing the belt to become disconnected while driving, the crankshaft will stop rotating while the camshaft is rotating, and the piston will be crushed when started. hits the open valve, the valve stem will also be bent or even deformed. At this time, the engine will need to be overhauled. Do you think it's worth it?
So when the car owner discovers the above situation while driving, he should immediately find a place to stop and check. The consequences of a broken timing belt are very serious. During daily maintenance of a car, you should also pay attention to the condition of the timing belt. Although it is recommended to replace it every 60,000 to 80,000 kilometers, it is best to replace it around 50,000 kilometers. If the timing belt breaks on the highway, it won't cost youare tens of yuan. The belt is so simple! Have you ever experienced a sudden breakage of your timing belt?
If the car belt is broken and you continue driving for a long time, the water tank will definitely boil because:
1. Since the car generator belt is a triangular belt, it is connected to the engine crankshaft, water pump and three parts of the generator;
2. As the above shows, if the generator belt breaks, the water pump will no longer continue to operate;
3. If you continue to drive, the engine antifreeze if there is no circulation cooling, the car will easily eat the cylinder seal. In severe cases, the car may be tiled. connected cylinder, etc.
