Is pulling the high speed before or after the first insurance?

What kind of high-speed is the new car pulling! Friend, do you want your car to be scrapped early? Don't take the word of those old drivers for it.

Understand the real reason for others at high speed, and the old driver cleans the pit people. It was a car from the carburetor era, and now you just need to drive well, and don't drive violently during the run-in period.

The so-called old driver doesn't know how to talk nonsense every day: some time ago I went to maintenance, and a guy who drove a joint venture car looked at my car, and then knocked on it and said, this sheet metal is really thin. I smiled and said nothing.

Some people always say that domestic cars are thin sheet metal, and thin means that the strength is not good? The strength of the steel plate depends on the material elements of the internal structure, not on the thickness of the problem. The strength of 10 thicknesses of high-strength steel may be much greater than that of 15 thicknesses of ordinary steel, which is a matter of material expertise.

Besides, the weight of the same level of sedan is basically the same, why does it say that the sheet metal of the joint venture is thick, if it is thick, it will be a large piece of weight high. So if you don't understand, you always tell others what you say, but in fact, you don't know what the real reason is!

If the car is first insured, it is generally half a year or about 5,000 kilometers, mainly to replace the oil filter, check the air filter, air conditioner filter, and pull the high speed after the first insurance.

The traditional saying is to pull before the first insurance, shake off the carbon deposits at high speed, and then the first insurance will discharge these wastes.

Hello, the so-called high-speed is generally the limit of running out of a car, after the first 5000 kilometers after changing the oil, in the open unlimited speed suburban road by the old driver, run to the limit of the car, the run-in period of a good car, can even run out of the theoretical speed value. But I personally do not recommend you to pull the high-speed, in fact, there is a misunderstanding of pulling the high-speed, the engine will produce great damage when overloaded and high-speed operation, especially new cars, many old drivers so-called high-speed, just to clean up the engine deposit, because the previous domestic gasoline is very low-grade, and Chinese drivers are generally low-speed shifts in order to save fuel, so the fuel is not very sufficient, resulting in engine carbon deposits, resulting in insufficient engine power, and the easiest way to clear carbon deposits is to run at high speed, The speed of the vehicle is controlled at more than 100km h, and it can run for about ten minutes. There is also a saying that the hot run-in of the engine, the domestic car has undergone a cold run-in after being produced, and the imported car has been run in both cold and hot because of technical reasons, so there is no need to deliberately run in, only need to jog for hundreds of kilometers to run in the tires.

So pull the high-speed saying a lot, it is recommended to do the first insurance, normal driving can be, if the limit value of the car is too much, even the engine will run the cylinder, affecting the service life of the car engine, the normal hot car all year round, each key position of the engine ignition is waiting for a few seconds, too fast ignition will reduce the life of the driving computer, occasionally add a little less high-grade steam will make the engine carbon deposit much less, occasionally run at high speed, the speed should not be too fast, safe driving, the car should not be borrowed, Only they will cherish their own car, the first insurance is best about 4500km to do, generally 4s more than 5000km will not give free first insurance, change the oil as much as possible to change the original factory, do not add the recommended so-called additives, oil additives do not have any benefits, add bad car I hope to help you, the new Bora car is good, if it is a turbocharged engine, when parking, wait for the engine speed to drop, and then turn off, because turbine engine maintenance is not cheap, they usually cherish the point, and there will be a lot less trouble in the future.

After the first guarantee, pull the bai highway.

It is recommended to maintain the new car for 2500 to 3000 kilometers (change the oil zhi and oil grid at your own expense), all.

DAO 4000 kilometers should be maintained, and the first warranty can be free of charge.

Do it again when it is 7500 or 8000 kilometers, and walk a little more for a longer time, so that the 4S shop can comprehensively check the problems after the operation of the vehicle engine and deal with it, which is good for your vehicle.

Before the first insurance, that is, the running-in period, the speed, the speed can not be too high, resulting in carbon deposition in the engine, after the first insurance run-in is completed, the waste engine oil and the like are also released, replaced with new engine oil, running high speed can burn off the previous carbon deposits, so that the engine enters a good working state. If you don't pull the highway, the carbon deposits in it may not be removed for a long time.

In fact, in the middle of the run-in, you should run a relatively high speed, which is good for the run-in. The real letting go of running must be after the first guarantee. A test run in the middle of the run-in can also hone yourself.

First of all, after the initial run-in of the engine of the new car, the operation of the parts tends to be harmonious. At this time, pulling and pulling at high speed, so that the engine can maintain high-speed operation for a period of time, can test the extreme working condition of the machine, and expand the resistance range of tensile, compressive, collision and torsion resistance of the parts and materials. Especially when working at high temperatures, the strength of metal materials can be greatly improved, and the overall performance of the parts can be further enhanced.

Therefore, it is not false that the new car can improve the performance of the engine by properly pulling the high speed, and the reason is here.

On the other hand, pulling the high speed also has a considerable effect on cleaning the oil circuit and cylinders of the engine. The reason is that when the engine is running at high speed, the oil supply increases, and the flow rate of the fuel also increases, which helps to wash out the dirt and impurities in the oil circuit to achieve the cleaning effect. Moreover, due to the high-speed movement of the piston, the temperature in the cylinder is higher, and the flow and speed of the air flow in and out of the valve are also high, and the combustion will be more sufficient, which is conducive to removing the carbon deposits of the valve and smoothing the blocked passage.

Therefore, it is self-evident that the power of the engine will increase after pulling through the high speed.

In order to make your car in better condition and more powerful, it is necessary to pull not only after the run-in period, but also every once in a while or a journey. This way you can go to the repair shop less. If you don't dare to drive so fast, you can also stop and step on the accelerator for a while.

The advantage of pulling the high speed is that when you run at high speed in the future, there will be no more hoarse roaring sound from before, and when driving at normal speed, the sound of the engine becomes better, and the acceleration is smoother and more powerful.

Preparations before pulling the highway:

1. After the first insurance is completed, the high speed will be pulled, because after the first insurance is completed, the torque of various screws and the hidden dangers of various liquid levels will be detected and investigated, and you can open it boldly with confidence.

2. Find a candidate according to the full load quality of the vehicle on the manual, if you can't find it, you can stuff things into the trunk.

3. Choose a safe route, remember to fill up the oil, and drive about 2,000 kilometers to change the oil after pulling the highway.

Finally, in order to avoid being fined for speeding on the highway, you can use the practice of high-speed and low-gear, that is, with three gears of 100 km/h, the speed can reach 4500 rpm. However, the low-gear high-speed pulling time should not be too long.

I thought it was very strange! Even angry!

Du actually came to zhi, and now some people suggest that vehicles should "pull the highway".

First of all, it is ridiculous to pull forward the high-speed of the first insurance! I haven't done any maintenance, what is the high speed?

Secondly, many people say that "pulling a high speed after the first guarantee" is actually completely unnecessary!! After the first insurance, you can use it normally! There's no need to do it at all!

Who told you that the first insurance front pull high-speed! This kind of person, you can basically say goodbye to dating! I didn't stop back when I bought the car.

Have you ever heard of a run-in? The run-in period is to let the engine run in, you drive a 180 and run in a fart! Don't pull the highway for too long! For example, 180 yards for 1-2 minutes is enough, and 3-5 pulls are enough.

It is the first guarantee after pulling the high-speed.

Reasons: First, the purpose of pulling the speed is to let the new piston and camshaft in the engine try to work quickly for the first time, so that they have better close contact with each other. In addition, the gears in the gearbox can be rotated at high speeds, so that the joint between the new gears and the gears is smoother.

After the first guarantee is completed, the torque of various screws and the hidden dangers of various liquid levels are detected and investigated, so that you can rest assured that you can pull the high speed.

Second, you can't pull the high speed before the oil change, because when the high speed is pulled, the engine working speed is high, the wear and tear of the machinery is the largest, and the first tank of oil is the most metal debris and the most impurities. In this way, the car will not be in the best condition after the run-in period.

First of all, we must understand the purpose and function of pulling the highway.

There are several types of pulling speeds, first of all, pulling up the speed of the engine for the purpose of burning carbon deposits. This practice is usually more than 30,000 kilometers of cars need to do, the first warranty of the new car before and after the maximum of 3,000 kilometers, carbon deposits have not reached the level of combustion, pulling the speed is just a needless increase in early wear, the gains outweigh the losses.

The second is high-speed driving, the purpose of which is to run in the gearbox. In fact, as long as the gearbox is running, it has been in a run-in state, the difference between low-speed run-in and high-speed run-in is only the length of run-in time, just like sharpening a knife, grinding 20 times per minute and grinding 60 times per minute, the fast speed will not grind better, but to achieve the goal faster. Instead, it increases unnecessary fuel consumption.

There is no need to deliberately run at high speeds for the sake of running-in.

You must know that now the new car gearbox, especially the high-speed gearbox of the car, has a wear-resistant soft metal coating on the surface of the gear, if you are forced to run high speed before the run-in is completed, it is easy to cause the soft metal strain and even peeling off and cavitation on the surface of the gear meshing, which is not a car at all but a ruined car.

Extended Materials:

The correct way to pull high speed:

Stop the car in a safe place, pull the handbrake, increase the throttle to 5000 rpm smoothly, and hold for 1 and a half minutes.

Then release the throttle to idle for 30 seconds, and then increase the throttle for a minute and a half, if the carbon deposit is not very serious, about every 5000 kilometers to do it, it is useless to do more.

Then accelerate the vehicle to a speed of 40 kilometers per hour when conditions permit, and then let go of the steering wheel to check whether the vehicle has deviation; Then speed up to 60, and listen to the engine, gearbox and chassis for abnormal noises.

Then speed up to 80, check again, and if you find any abnormal response, write down the speed of the vehicle and the engine speed at that time.

Then stop immediately for inspection. In the parking neutral state, pull the engine up to the same speed to see if there is any abnormal noise, if so, it means that the abnormal noise is from the engine, if not, it means that the abnormal noise is from the gearbox or chassis.

After the first insurance, pull the high speed, because after the first insurance, the torque of various screws and the hidden dangers of various liquid levels are detected and checked, and then you can drive safely. According to the full load mass of the vehicle in the manual, all candidate vehicles are found. If you can't find them, you can put something in the trunk.

Choose a safe route, remember to fill up the fuel, then drive about 2000 kilometers, and change the oil after pulling the highway.

There are two criteria for the first insurance. One is time, the other is mileage. Generally speaking, two to three months of initial insurance is a standard, and 3000 kilometers is a standard.

These two standards are based on the manufacturer) and the standard that arrives first prevails. You've only been running 600 kilometers in two months, and you can see that you really don't need to buy a car. Also, when it comes to pulling the highway, it's better not to pull.

It's for you. First of all, there is no need for today's cars to pull at high speed or not. Second, you only run 600 kilometers in two months.

Can you adapt to high speeds? If you really want to use high speed to remove carbon deposits from the silver source machine, only if the speed is above 160 can it be effective.

Strictly speaking, the run-in period of the vehicle does not simply mean the run-in period of the engine, but also the run-in period of the drive system, braking system and various circulation systems. At present, the engines of many high-end cars use high-tech grinding technology, and the assembly accuracy is also very high. However, I think it is good to drive cautiously during the run-in period, and generally the first insurance can be about 1000-2500 kilometers (and it is best not to exceed 3 months).

When it comes to high speeds, this is an old problem. First of all, the high speed is not a simple high speed to high speed, but a period of stable operation under the high-speed conditions of each gear (generally in addition to overdrive, each gear can run at 4000-5000 rpm for 1-2 minutes). Moreover, the high speed should be gradual and gradual, and it is harmful to the engine if you do not pull the red line as soon as you come up.

It is best to gradually increase the running speed from 2000-2500 rpm until the desired effect is achieved. Therefore, it is advisable to set the break-in period and then change the oil before pulling up the rpm.

The first car warranty is the first maintenance after the car is purchased, and it is a very important maintenance for a new car. However, many car owners will have a question when carrying out the first insurance, that is, is it better to pull the high speed before the first insurance or pull the high speed after the first insurance?

First of all, we need to understand the meaning of car first insurance. The first warranty of the car is mainly to check and adjust the performance of key components such as the engine, gearbox, suspension, and braking system to ensure the normal operation and safety performance of the car. Therefore, if the speed is pulled before the first warranty, it will cause a large load and pressure on the vehicle, which may cause damage to the key components of the new car or affect its performance.

Secondly, the high speed after the first guarantee can effectively promote the operation and running-in of the engine, which is conducive to the performance improvement of the engine. At this time, the various parts of the car have been inspected and adjusted, and after the maintenance is completed, the overall performance of the vehicle will also be improved. Therefore, pulling the highway after the first warranty is good for the health and performance improvement of the car.

To sum up, for new cars, it is a more suitable choice to pull the highway after the first warranty. However, it should be noted that before pulling the high speed, the vehicle needs to be fully warmed up to avoid unnecessary damage to the vehicle. At the same time, it is also necessary to pay attention to the time and place of pulling the highway to avoid affecting the safety of other vehicles and pedestrians.

Finally, remind car owners that before or after the first warranty, they need to comply with the maintenance recommendations and requirements of the car manufacturer, and regularly maintain and maintain the car to ensure the normal operation and safety performance of the car.
