How often are car high voltage wires replaced? What is the good impact of replacing the high voltage

The recommendation for automotive high-voltage wires is to replace them once every 4-50,000 kilometers. Once the high-voltage line is damaged or aged and not replaced in time, the energy value of the ignition will be greatly reduced, the fuel consumption will rise, the power will decrease or even the fire will be cut off.

At present, the battery used in the car on the market is generally 2-3 years, and it may need to be replaced with a new one, if the car is usually well maintained, it can also be used for 3 or 4 years, but if it is often used violently, the battery may be scrapped in about a year. Many people think that car batteries do not need to be replaced, but this is actually wrong.

4w kilometers to change the feeling of power dropped, change the spark plug and high-voltage line, the high-voltage line can also be used again;

The high-voltage line must be replaced for a long time, because the high-voltage line transmits electricity, because electricity will make people hurt and cause unhealthy health;

It is a maintenance item, and it must be replaced regularly, and it must be replaced even more if it is broken.

Hello, there is no replacement cycle for automotive high-voltage wires, as long as it works normally, it does not need to be replaced, and its service life is generally 100,000 kilometers or even longer.

The automobile high-voltage package includes a high-voltage ignition coil, a transformer device, and a locomotive high-voltage envelope.

The line of the car is often a point that the owner is very easy to ignore, most car owners may know the engine, gearbox, brake system and other important parts of the car, and the line is very unfamiliar with this part.

From the internal structure, the high-voltage line has a single core, three cores, four cores, and five cores, the more cores, the smaller its resistance, the higher the ignition intensity, but then the higher the **!

There is also the well-known high-voltage ignition wire using silicone technology, which can withstand temperatures ranging from -40 to 220 degrees. However, the more inner cores, the greater the current that passes, which requires a better shielding material for the outer packaging of the high-voltage wire, otherwise electromagnetic interference will be generated. The prolonged heat, dust and vibration in the engine compartment during driving will inevitably cause aging and even damage to the high-voltage line.

As for how often the high-voltage line should be replaced, the safer recommendation is: replace it every 4-50,000 kilometers. The high-voltage line itself is not high, but most of them are produced and sold in sets.

Foreword: When people buy a car, few people will consider consulting some knowledge about the interior parts of the car. Under what circumstances do we need to replace the high-voltage wires of the car?

1. What are the problems of the damage of the high-voltage line of the car, if the high-voltage line of the car is damaged, the power will be insufficient, the engine is in the process of working, the spark plug of the car is a discharge spark, the ignition energy of the spark plug will be insufficient, and there is no way to better ignite the gas, so the engine of the car will be short of cylinders at this time. If the high-voltage line is seriously damaged, then the fire plug ring can not even release an electric spark at this time, and the power of the car will be significantly reduced at this time. At this time, the fuel consumption of the car will also be greatly increased, and the engine will shake violently in the process of working, and the noise will be very obvious, which will further affect the comfort of the driver.

2. What symptoms will occur If we find that the power of the car is insufficient during the normal driving process of the car, sometimes there is a high and a low situation. At this time, we have to consider whether there is a problem with the engine of the car, or there is a problem with the high-voltage line of the car. Usually, the load current of the car is returned by various electrical equipment through the body, and if the engine has a serious shake, it also indicates that there is a problem with the car's battery system at this time.

3. How to know if there is a problem with the high-voltage lineIf we want to know whether there is a problem with the high-voltage line of the car, we can use a voltmeter or measure whether the two ends are energized, pull the high-voltage line from the spark plug, and put the high-voltage line close to the iron, Yin Changhui, and then go to the fire, if the flashover between the high-voltage line and the wire, it means that the high-voltage line is energized. Generally speaking, the common form of damage to the high-voltage wire is open circuit or leakage, we can remove the high-voltage wire from the engine of the car carefully, if there is damage or leakage, it should be replaced.

That is, some circuits of the car have been affected by the rubber sound, and when the normal driving is slow, it will also encounter the problem of Shenheng, which needs to be replaced at this time, so as not to cause a serious impact on the body of the electric connection.

The fixed speed of the car slows down, and the car will have some faults when it is in gear, the car will rush one after another, and the car will be weak.

When the car can't hit the friendly fire, when the gear is not strong, when there is no power difference, the car will rush when it starts, and it should be replaced at this time.

First of all, it is necessary to remove the old high-voltage line, and then make the new high-voltage line rough to achieve the length of the high-voltage line, and then go to the repair shop to find a maintenance master to help you change the rock.

First of all, remove the old wire, and then select the first line and then install it, be sure to pay attention to the circuit safety, and do not start the engine when changing.

First of all, you need to open the hood of the car, and then choose to remove these old ones, and then install the high-voltage wires of the car.

The high-voltage line of the car is mainly to ensure that the ignition line and fuel are set, and if the high-voltage line of the car is replaced, it can be a good solution to the acceleration weakness. However, if the high-voltage wiring of the car is damaged, it will also lead to an increase in the car's fuel consumption. These are very serious injuries to the car, so if the above symptoms are found, the high-voltage wire should be replaced in time, so that the loss will be minimized.

How often should the high-voltage wire be replaced? Most people understand that spark plugs are susceptible to damage, so they should be replaced regularly. However, little is known about high-voltage wires, and many people do not know that high-voltage wires in cars also need to be replaced regularly.

Because when you start the car, there will be tens of thousands of volts of current on the ignition wire. Long-term wear and tear will lead to the aging of the high-voltage line, and if it is not replaced regularly, then there will be an increase in fuel consumption and a slow decrease in power. So after about 4 or 5 kilometers of driving, the high-voltage line needs to be replaced.

How do you maintain your car on a daily basis? In addition to the maintenance of car accessories, the most important thing is the maintenance of the body. Many car owners will choose to wash their cars frequently, which can not only make the body look new, but also find the damage on the body in time.

If there are dents or scratches on the car, it will greatly affect the overall aesthetics. In this case, you should deal with it in time and find a professional 4S shop to take care of yourself. And you can also wax the body frequently, and pay attention to covering the car when you usually park.

How do I take care of the tires in my car? Tires are a very important accessory for cars, but many people should know that there are some grooves on the surface of tires. These grooves are a great way to increase the friction of the tire, especially when driving in rainy weather, and if they are not available, it is likely to cause the tire to slip.

Therefore, it is necessary to replace the grooves regularly to prevent the grooves from being worn out over time.

Pacific Automobile Network] The recommendation for automobile high-voltage lines is to replace them once every 4-50,000 kilometers. Once the high-voltage line is damaged or aged and is not replaced in time, the energy value of the ignition will be greatly reduced, the fuel consumption will rise, the power will decrease or even the ignition will be broken.

The high-voltage line has a single core, three cores, four cores, and five cores, the more cores, the smaller its resistance, the higher the ignition strength, but then the higher the pretension. In addition, the well-known high-voltage electric fire wire uses silicone technology, which can withstand temperatures ranging from -40 to 220 degrees and high voltages up to 35kV. However, the more inner cores, the greater the current that passes, which requires the outer packaging of the high-voltage wire to use better shielding materials, otherwise it will produce electromagnetic interference and interfere with the car audio or driving computer.

Many people know that spark plugs are consumables, which need to be replaced frequently, but for other parts of the ignition system such as high-voltage lines, they are often ignored, once the high-voltage lines are damaged or aged and not replaced in time, the energy value of ignition will be greatly reduced, fuel consumption will rise, power will drop and even fire failure, these huge injuries are fatal blows to engines with three-way catalysis, so it is imperative to regularly check and replace high-voltage lines.

From the internal structure, high-voltage lines.

It can be divided into single core, three core, blind four core and five core. The more cores, the smaller the resistance, the higher the ignition intensity, but the higher! In addition, well-known high voltage.

The gas fire line adopts silicone technology, which can withstand the temperature range of -40 to 220 degrees and the high pressure can reach 35kV. However, the more cores there are, the greater the current that can be passed, which requires better shielding materials for the outer packaging of high-voltage lines. Otherwise, electromagnetic interference will occur.

Interfere with car audio or drive a computer.

Delete an old line, compare it to the new line, select a line of the same length, and connect the line. This method is the same until it is replaced; It may be that the length of the old lines is different; Remove an old line, compare the length with the new line, and choose the most appropriate plug length, remembering which row of the old line is in which position.

Due to the limitations of the coating material, the high-voltage wires on ordinary cars are designed with resistance to prevent electromagnetic interference, but this resistance value will reduce the transmission efficiency of the wires and cause current loss. If the wire coating material is changed to silicone.

can solve the interference problem; It can also greatly reduce the resistance value and reduce the losses caused by high-voltage current transmission. The original high-voltage line is copper wire inside and heat-resistant rubber outside; The silicon wire has a carbon core on the inside and two to three layers of silicone resin on the outside for insulation and heat insulation;

Electrical conductivity of copper wires.

It is very high, even better than the carbon core wire used for silicon wire, but the head and tail plugs are slightly less conductive, and they emit large electromagnetic waves when the engine is running at high speed.

Interference with the in-car audio system, due to the high temperature of the engine, the rubber on the outside will burn. When replacing, it should be noted that the ** of the high-voltage line is not very expensive, but most of the high-voltage lines are produced and sold in sets. Because the length of the high-voltage line of each cylinder block is different, it is difficult to buy one!

Even if the merchant is alone, it will be a lot.

I think we must seek the help of professional and technical workers, and we must choose the right size and the right model when replacing, and we should also choose the right tools for Ye Qiju, and then we also need to find the right position for the change.

You should find a professional person to replace it, which can solve a lot of problems, and it is also safer and more secure.

I think it would be better and more convenient to choose some reasonable high-voltage cables and replace them.
