Does it affect the uphill start three or four times during the run in period?

Due to processing and assembly errors, the frictional resistance of the moving parts of the new car is always much greater than normal when it starts to run, and the running-in (also known as walking) effect in the early stage of the car will have a great impact on the service life, working reliability and economy of the car. Therefore, the run-in regulations must be strictly implemented when using new cars.

1. Run-in regulations for new cars within 1000 kilometers:

1) Never drive at full speed.

2) - Generally not to drive at a speed of more than 100 km/h.

3) Avoid driving at high speeds in all gears.

2) The run-in of the vehicle between 1,000 and 15,000 km: it can be gradually increased to the maximum speed or at the maximum permissible speed of the engine.

2. After the run-in period, attention should be paid to:

1) When driving a car with a tachometer and shifting into the approaching high speed, the maximum engine speed allowed for a short time is 5 500 rpm when the pointer reaches the red indication zone at the latest. The maximum permissible speed in each gear is 40 kmh in the first gear, 65 kmh in the second gear, 100 kmh in the third gear, 135 km/h in the fourth gear, and 165 kmh in the fifth gear.

2) Avoid running the engine at unnecessarily high revs, and switch to high gear early to save fuel and reduce noise.

3) Do not drive the engine speed too low, and only change to low gear when the engine is working hard.

4) The speeds and rotational speeds listed in the instructions are only applicable to engines with normal temperatures. When driving cold, do not allow the engine to work at the highest revs, whether in neutral or in other gears.

5) New tires don't have optimal adhesion when they start with use, so new tires also need to be walked, slower for the first 100 km, and driven with care.

6) The new brake friction plate also needs to be run-in, in the first 200 kilometers of driving, there is not yet the ideal friction, if the braking effect is slightly worse at this stage, the pressure of the pedal can be appropriately increased. The same applies after each subsequent replacement of the brake pads.

7) Under possible conditions, the new car should avoid continuous driving for a long time during the run-in period, so as to avoid the engine and chassis parts continue to work for too long, resulting in the aggravation of the wear of the parts, and directly affect the service life of the car. Also avoid running at full load, generally in the first 1000 kilometers of driving, it is best to run below 80% of the rated load. Also, try to avoid driving at high speeds and don't go faster than 70% of the top speed with the throttle open for the first 2,000 km/h.

8) during the run-in of the new car, the driver should heat up in situ after the new car starts at the beginning, and then start after the water temperature rises to the working temperature range, and should choose a good road surface during driving, and slow down when the road condition is poor; When driving, the throttle should be smaller, the operation should be light, once the engine or chassis sound is found to be abnormal, it should be stopped to check the fault in the embryonic period.

No, but there are still caveats.

There are several major taboos during the run-in period of the new car:

1.Do not brake urgently.

Emergency braking not only impacts the braking system during the break-in, but also increases the shock load on the chassis and engine. During the first 300 km, it is best not to brake suddenly.

2.Do not overload.

If the new car is running at full load during the run-in period, it will cause damage to the parts. Therefore, within the first 1000 kilometers, the general load capacity should not exceed 75%-80% of the rated load.

3.Do not run long distances.

When the new car runs long distances during the run-in period, the continuous working time of the engine will increase, which is easy to cause wear and tear of parts.

4.Do not drive at high speeds.

There is a speed limit during the run-in period of new cars, and the speed of domestic cars is generally 40-70 kilometers per hour, and imported cars are generally within 100 kilometers. When the throttle is fully open, the speed of the car cannot exceed 80% of the top speed.

5.Do not change the oil too early.

The initial oil of the automobile is a special lubricating oil for the run-in period, which requires low viscosity, good heat dissipation, superior cleaning and oxidation resistance, and some car factories also add abrasives that are conducive to running-in. Therefore, the oil during the run-in period only needs to be changed according to the time specified by the manufacturer, and should not be changed too early.

Before the car leaves the factory, only the engine block has been cold-run without load. Formal driving is a thermal run-in with loads, including: brake system run-in, drive shaft, wheel run-in, etc.

Cars with poor run-in have noisy engines, fuel consumption, and weak acceleration. Therefore, the first few thousand kilometers of the new car are called the run-in period.

Start and stop gently, and brake slowly often to make the brake pads run in better. Try to be the only one in the car, don't carry too many passengers, and drive lightly. How do you run these 500 kilometers?

40 km h, 60 km h, 80 km h each run at a constant speed of 100 km, and the other kilometers are normal starts. Parking and driving on city roads (20-30 km). When there is more than one person on the bus, the speed of the vehicle should not exceed 60 km h.

Presumably, no matter who you are, the moment you get the keys to the new car, you must be full of excitement in your heart, and you can't wait to drive your new car for a ride, and at the same time you can familiarize yourself with the new car as soon as possible. But did you know that there are many precautions that may be overlooked during the run-in period of a new car, and the direct impact of ignoring these problems is that it will affect the performance of your car? Next, let's take stock of the most important speed issues and other precautions during the run-in period of the new car.

1. About the driving speed of the new car during the run-in period.

2. The impact of too fast speed during the run-in period of new cars.

3. The impact of too slow speed during the run-in period of new cars.

4. Other precautions for driving during the run-in period.

When the new car is driving during the run-in period, it is quite taboo to mismatch the speed gear, which is not only unfavorable to the run-in of the gearbox, but also will cause damage to the gearbox. Shift gears in time while driving, avoid mismatched speed gears, and do not use one gear for a long time. In addition, do not push the speed to the limit in each gear, and each gear can refer to the following standards:

1st gear 25 km, 2nd gear 40 km, 3rd gear 60 km, 4th gear 90 km, 5th gear 100 km. Although automatic transmission cars do not have to worry about gear and speed, they should also pay more attention to the engine speed.

How about it, there are still a lot of knowledge points in the run-in period of the new car, have you noticed these places?

For new cars that are still in the run-in period, pay attention not to exceed this speed, which will not only hurt the car but also be dangerous.

The time period of the run-in period is generally before the first insurance, and the run-in period is considered after the first insurance. During the run-in period, many parts of the vehicle, especially fine parts, need to be run-in, so if the car is well maintained during the run-in period, it can effectively increase the service life of the vehicle, and the probability of problems with the car in the back is also lower. During the run-in period, the following issues need to be paid attention to.

First of all, the driving habit should be soft, not strenuous driving, such as sharp acceleration, sharp braking, sharp turns, etc., and it is best not to go on the high speed first, because the strenuous use of the car will cause the engine, brake, throttle, steering, chassis and other systems to react and move violently without running-in, which may cause damage to the components in the system, and these fine parts are difficult to get through maintenance.

Secondly, during the run-in period, the speed should not exceed 80 kilometers per hour, and the engine speed should not exceed 3000 rpm, which is more beneficial to the maintenance of the engine. It is recommended to drive at low and medium speeds as much as possible, so that sudden braking can be avoided as much as possible.

In addition, do not use the car for a long time during the run-in period, generally use the car for 2 3 hours at most, you need to let the car rest for a while, too long to use the car will make the vehicle load heavier, and the car may cause damage to the car during the run-in period under overload. Also, don't go to a section of the road in bad conditions, or drive in the rain or wading for a long time, the new car can't withstand such a toss.

Finally, of course, during the run-in period, you should be careful with the car, and avoid traffic accidents such as collisions and collisions, because accidents will not only directly damage the car, but also cause many fine parts to be affected, which can be said to be irreversible.

In fact, the car is relatively fragile during the run-in period, so it is best to protect it well, which is good for the performance and durability of the car. Love the car as a lover, if you are good to it, it will be good to you.

With the increasing advancement of automobile technology, many people have said that the car run-in is the product of the underdeveloped cycling industry and the imprecision of auto parts, and now the technology is so good, the new car does not need to run in at all, as long as you buy it back, you can open it directly, and there is no need for any precautions for fuel pedal, brakes, speed, etc., and there is no need for any run-in period. Is this true? Obviously this is not right!

A new car is a must!

So what do you need to pay attention to during the run-in period of the new car? Just remember the following facts, and you don't need to pay too much attention.

1. Remember to drive at high speed for a long time.

2. Remember to drive with full load, and during the run-in period, try not to brake urgently within 75% of the vehicle weight within 75% of the kilometer.

4. Proper heating of the car is needed in winter, and turbocharged vehicles are even more needed.

5. Do not add engine wear-resistant additives during the run-in period.

Generally no more than 80

The run-in period of the new car is generally about 2000 kilometers, and the run-in period is to exercise the performance of the car engine, so during this period we must do a good job of running in all aspects of the car, do not exercise high speed during the maintenance period, control it below the maximum of 80 yards, operate it steady, and step on the clutch to the end when the gear is suspended, and you can exercise high speed after running to 2000 kilometers, and you will also feel that the strength of the car is slightly greater.

In fact, the run-in is not only applicable to the engine, the gearbox is also to be run-in, which is the reason for the shift in the first 100 kilometers, the manual transmission model will be relatively stable, the clutch is stepped on the end of the shift, and then gradually lifted to complete a shift, but to prevent the clutch from stepping half to the gear, at this time not only the gear is very difficult to hang, and there is a very serious injury to the gearbox.

How many kilometers does a new car have to travel before it can pull the highway?

Generally speaking, it is not advisable to run at high speed within 200 kilometers of a new car, because the tires and brakes have not yet been run-in, which affects braking. It is best to avoid running at high speed within 2000 kilometers, and it is best not to run for a long time and continuously when you have to run, and then run at high speed after running a non-high-speed period after 15 minutes in a row, of course, this is also a recommendation, and it is also suitable for old cars.

The so-called run-in period of a new car, most car owners who have just bought a car know a little. However, it is more scientific to maintain the speed of how many kilometers can not be on the highway, and many people may not have experience. Although the current engine assembly has been adjusted at low speed and high speed, and some cars are known as zero kilometers of running-in, but for the power system of the car, not only the engine, but also many other aspects are recommended to be well run-in.

In our interviews with some of the senior mechanics, we learned that their advice:

The first is not to create high-speed operation too early. Even if the engine is tested at high speeds, it is a test without load.

Specifically, within 2500 km, it is recommended that the speed of each gear should not exceed 20 yards in 1st gear, 40 yards in 2nd gear, 60 yards in 3rd gear, 80 yards in 4th gear, and 100 yards in 5th gear.

The main purpose of the automatic transmission model is to make the new clutch engagement smooth, the gearbox gears are well engaged, and the power output is smooth.

But be careful, don't always run in a certain gear. In order to avoid the serious heating of the gears of this group, the internal heating of the gearbox will be unevenly deformed, and the metal chips will be generated if there is a problem with the occlusion when changing gears. We all know that many metal parts need to be placed in the natural environment for a period of time after they are produced, so that they can be annealed naturally, and the internal stress is balanced everywhere, and the run-in of the car is also the same reason.

Break-inIt is the process of combining the components in the car, but more importantly, the process of combining people and vehicles. Run-in is also called walk-in.

Car break-in periodIt refers to the initial driving stage after the new car or overhaul, generally 1000-2500 kilometers, which is the basic mileage to ensure the full contact, friction, adaptation and finalization of the parts. During this period, the ability of each part of the car to adapt to the environment can be adjusted and the protrusions on the parts can be sharpened. The quality of the car run-in will have an important impact on the life, safety and economy of the car.

1. 500 kilometers of the new car is the initial run-in, the speed should not be too fast, generally 70-80 kilometers below, and the speed should not exceed 2200 revolutions; 500-1000 km is the mid-term run-in, the maximum speed can be appropriately increased, generally can reach 90-100 km, and the speed is still below 2500 rpm; 1000-1500 km is the later run-in, the speed can be increased to less than 120 km, and the speed should not exceed 3000 rpm.

2. Other precautions during the run-in period of the new car:

a. When all cars are driving at low speed, the actual burden is greater than that of medium speed, so the run-in period should not be run in below 60 kilometers per hour for a long time. The speed must be gradually increased, if the speed has been running at 80 kilometers per hour after the run-in period, the sudden increase in speed will make the new car unsuitable, so it is necessary to gradually increase the maximum speed during the run-in period.

b. Avoid sudden braking and rapid acceleration during the running-in period.

c. Preheat before starting.

d. Avoid overload, the new car will cause damage to the parts when it is fully loaded.

e. Do not run long distances, new cars run long distances, which will increase the continuous working time of the engine and aggravate the wear of parts.

g. During the run-in period of the new car, the oil, coolant and battery electrolyte should be checked frequently, and the lack must be replenished in time. After reaching a certain number of kilometers (during the run-in period or after the end), it is necessary to go to the service station in time to inspect and maintain the vehicle, change the oil, filter, etc., and comprehensively check the chassis system. Generally speaking, it is necessary to change the oil once after walking about 1500 kilometers.
