What are the precautions during the run in period?

The speed should not exceed 100, and the journey should be more than 3000km after pulling down the high-speed, and it is recommended to add 97 or 95 oil to save money!

The following points should be paid attention to during the run-in period of the new car.

1.It is best to warm up for 3 to 5 minutes after starting, and wait for the engine water temperature to come up. Note that the warm-up time should not be too long. Engines that are too long are prone to carbon deposits.

2.When driving, the engine speed is not too high, not higher than 3000 rpm is fine.

3.Do not load the car more than 70% of the rated load

4.Don't brake suddenly. Rush to the direction.

5.Do not drive faster than 80 yards.

6.When killing the direction, you should go back a little. The time should not exceed 3 seconds.

The first warranty should be done in time, because there are more iron filings in the new engine. Generally, the first warranty for new cars is 3000 kilometers or 3 months, whichever comes first will prevail.

SAIC Volkswagen Langxing manufacturers suggest that Volkswagen Langxing run-in period is 3000 kilometers 300 days, there is a speed limit during the new car run-in period, generally within 40-70 kilometers, when the throttle is fully open, the vehicle speed can not exceed 80% of the maximum speed, and pay attention to the engine tachometer and speedometer in driving, under normal circumstances, the engine speed during the run-in period should be 2000-4000 rpm; Precautions for Volkswagen Langxing when using it during the run-in period:

1. Preheating at the start: This is for the EFI car, before starting, you should turn the key to the second gear and wait for 5-10 seconds, and then start, this is because after the key door is opened, the gasoline pump will start to work, so that the oil pressure and fuel injection volume will be adjusted, therefore, start after a few seconds to protect the new car engine;

2. Avoid emergency braking: emergency braking not only makes the braking system in the run-in be impacted, but also increases the impact load of the chassis and engine, and it is best not to brake urgently within 300 kilometers of the initial driving;

3. Avoid overload: If the new car runs at full load during the run-in period, it will cause damage to the parts, therefore, within 1000 kilometers of the initial driving, the domestic car can not exceed 75%-80% of the rated load, and the imported car can not exceed 90% of the rated load.

4. Avoid running long distances: If 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 the parts; The boy will return.

5, do not drive at high speed: there is a speed limit during the run-in period of the new car, the domestic car is generally within 40-70 kilometers, the imported car is generally within 1000 kilometers, when the throttle is fully open, the speed can not exceed 80% of the maximum speed, and pay attention to the engine tachometer and speedometer during driving, to ensure that the engine speed and speed work at medium speed, in general, the engine speed during the run-in period should be 2000-4000 rpm;

6. Use high-quality gasoline: the gasoline used by the new car during the run-in period should not be lower than the label specified by the manufacturer, and high-quality gasoline should be added as much as possible, and anti-wear oleaceum should not be added, so as not to have enough mileage and insufficient run-in;

7. Do not remove the speed limiter in advance: the speed limiter is a throttling device installed between the carburetor and the intake pipe, the owner can not remove it in advance, and should wait for the new car to travel 1000 kilometers before removing it under good maintenance;

8. Timely shifting: timely shifting is to avoid high gear low speed and low gear high speed, do not use a gear for a long time, and do not make the speed reach the limit in each gear, generally speaking, the speed of each gear is controlled in the range of top speed 3 4, specifically: 1 gear 25 km, 2 gear 40 km, 3 gear 60 km, 4 gear 90 km, 5 gear 100 km;

9. Correctly adjust the ignition system and oil supply system: this can solve the changes in the vacuum economizer caused by the installation of speed limiting plates, and improve the economy of the running-in period.

According to its instructions, it is 3000 km.

Several things to pay attention to during the run-in period:

1.Control engine speed:

The run-in period is not to control the speed of the car, but to control the speed of the engine, the engine speed is controlled between 2000-3000rpm (gasoline engine) The load of the engine is the lightest, due to the poor lubrication during the run-in period, too high speed is easy to strain the components, the speed is too low (the gear is too high), the power of the engine to do work becomes an impact, which will also cause wear, so it is necessary to change gears frequently to control the engine speed. Automatic transmission cars only need to control the engine speed below 3000rpm.

2.Load Reduction:

During the run-in period, because the best lubrication state of the sensitive belt can not be reached, the heavy load will aggravate the wear, so the load should be minimized in the first 500 kilometers, and the maximum load should not exceed 50% during the 3000 kilometers run-in period, and the load will be gradually increased after the running-in period. In addition, the braking system is not fully running-in, the braking effect is not good, and the load also needs to be lightened.

3.Don't change the oil too soon:

The initial oil of the car is a special lubricating oil during the run-in period, which requires low viscosity, good heat dissipation, superior cleaning and oxidation resistance, and some car factories have also added abrasives that are conducive to the run-in, so the oil should not be replaced too soon during the run-in period. There is no need to worry about excessive abrasive debris as they will remain in the filter and the oil can be changed at the time specified by the manufacturer. It is also important to change the oil after the break-in period, and a lower viscosity oil is still required.

4.Do not use additives:

New car owners are not Li Mo who often cherishes their new cars, and at this time they are also the most likely to be persuaded to buy some so-called "protective supplies". After additives are added to the engine oil during the run-in period, it will seriously affect the run-in effect, prolong the run-in period, and even produce a chemical reaction with the oil additives, forming oil sludge or bubbles, which will reduce the oil pressure, and at the same time make the lubrication worse and accelerate the speed of wear, so do not use any additives during the run-in period.

5.Warm up before you start:

The new car must be warmed up before starting, the so-called preheating is actually to give the engine a full lubrication time, because the lubricating oil can not reach the friction surface immediately after starting, so it is necessary to wait until the lubricating oil has reached all the parts that need to be lubricated (especially turbocharged models) before starting. The time for adequate lubrication varies depending on the air temperature, oil viscosity, and permeability of the oil filter, so it takes at least one minute to ensure that the lubrication is in place.

Hello, within 3000 kilometers of the run-in period of Lang Demolition Sun Dong Zheng Code, it should be noted that the cold car idles for five minutes before starting, do not accelerate sharply when driving, the maximum speed should not exceed 100 kilometers per hour, and the maximum speed should not exceed 3000 rpm, I hope it can help you.

Within 3,000 kilometers of the run-in period, it should be noted: the cold stool car idles for five minutes before starting, do not accelerate sharply when driving, the maximum speed should not exceed 100 kilometers per hour, and the maximum speed should not exceed 3000 rpm.

Don't rev and shift gears too quickly. Try to drive at a constant speed as much as possible3Gasoline can be hailed with a good point, such as the 4 of No. 97

Don't use the car every day to imitate the sails too long, avoid long distances and high speeds. 5.The load should not be too large, pull a lot of people, so as not to make the engine power too heavy compared to the new car.

The following points should be paid attention to during the run-in period:

1) When driving a vehicle, you should try to avoid high-speed driving, long-distance driving, and full load driving, and try to let the engine have a warm-up process before driving, so that the internal parts of the engine can be fully lubricated.

2) First of all, it is necessary to strictly control the speed and engine speed, and try not to exceed 90 kilometers per hour and the speed of the engine should not exceed 3000 rpm during the run-in period, so as not to cause excessive load on the engine and gearbox and other components, but also try not to let the vehicle be in a low-speed driving state for a long time, and change gears in a timely manner during the driving process, so that the gearbox can be fully run-in.

3) In the process of driving, it is necessary to avoid the operation of rapid acceleration and sudden braking, because this kind of operation is easy to cause a large impact on the engine, gearbox, braking system, chassis and suspension.

In terms of power, Langdong will be equipped with an engine and a NU engine, of which the engine has a maximum power of 127 hp and a maximum torque of 155Nm, while the latest NU engine has a maximum power of 145 hp and a maximum torque of 175Nm. In terms of dynamics, the new car will be mated to a 6-speed manual transmission and a 6-speed automatic transmission, which will bring better power transmission efficiency and fuel economy compared to the current 4-speed automatic transmission of Yuedong.

Langdong new car run-in period, refers to the new car after the factory, the first time to drive a distance to make the engine parts of the run-in smooth period, the new car run-in mileage is generally 1000 kilometers - 3000 kilometers, roughly speaking, the new car run-in period has the following characteristics:

1. There are many driving faults: due to factors such as improper assembly of various components, there are many driving faults in the run-in period of new cars;

2. High fuel consumption: In order to ensure that the new car runs under a small load during the run-in period, the carburetor car is equipped with a speed limiting sheet, so it is easy to cause the mixture to be too thick, so as to increase the fuel consumption;

3. Lubricating oil is easy to deteriorate: during the run-in period of the new car, due to the rough surface of the parts and the small gap between the two parts, the temperature of the lubricating oil will rise, and at the same time, many metal chips will be worn off and fall into the lubricating oil, which is easy to oxidize and deteriorate the lubricating oil.

Precautions for the use of new cars during the run-in period:

1. Preheating at the start: This is for the EFI car, before starting, you should turn the key to the second gear and wait for 5-10 seconds before starting, this is because after the key door is opened, the gasoline pump will start to work, so that the oil pressure and fuel injection amount will be adjusted, therefore, start after a few seconds to protect the new car engine;

2. Avoid emergency braking: emergency braking not only makes the braking system in the run-in be impacted, but also increases the impact load of the chassis and engine, and it is best not to brake urgently within 300 kilometers of the initial driving;

3. Avoid overload: If the new car runs at full load during the run-in period, it will cause damage to the parts, therefore, within 1000 kilometers of the initial driving, the domestic car can not exceed 75%-80% of the rated load, and the imported car can not exceed 90% of the rated load.

4. Avoid running long distances: If 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 the parts;

Precautions for the break-in period of automatic transmission.

Each car may be slightly different (e.g. speed), but the principle of speed is the same, let's take a look.

500 kilometers for the initial run-in, at this time the speed should not be too fast, generally 70-80 kilometers below, the speed should not exceed 2200 rpm as well.

1000 kilometers is the mid-term run-in, the maximum speed can be appropriately increased, generally can reach 90-100 kilometers, and the speed is still below 2500 rpm. Increasing the speed appropriately will not only not affect the engine, but can promote the running-in, and you can see if there is any abnormality when the speed is increased again.

1500 kilometers is the later run-in, and the speed can be increased to less than 120 kilometers. Because running-in is a gradual process, it must be gradually increased. The speed should not exceed 3000 rpm.

4. 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 increased gradually. At the same time, if you have been running at a speed of 80 kilometers per hour after the run-in period, a sharp increase in speed will make the new car unadaptable, so it is necessary to gradually increase the maximum speed during the run-in period.

5. Do not drive at a fixed speed for a long time during the run-in period, and there should be a speed change.

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

In the case of automatic transmission, the run-in specified gear cannot be determined by manual gear shifting, so it can only be achieved by driving speed. In short, the run-in should be driven at a constant speed, 30km h

Easy car netizens.

The quality of car running-in will have an important impact on the life, safety and economy of the car. The run-in mileage of cars is generally 1,000 to 2,500 kilometers, and imported cars are longer, mostly 1,500 to 3,000 kilometers. The run-in period is divided into 3 phases.

That is: 100 kilometers at the initial stage, 200 kilometers at the beginning of running-in, and 3000 kilometers at the run-in to form an oxide film.

In order to let our car pass the run-in period smoothly, we should do a good job of inspection and maintenance at ordinary times, and pay attention to the following aspects to improve the quality of the run-in.

1) Preheat up at the beginning.

Before the EFI truck starts, you should turn the key to the second gear and wait for 5 to 10 seconds before starting. After the key door is opened, the gasoline pump is turned on to adjust the oil pressure and fuel injection volume, so it is good for the motor and engine of the car to start it after a few seconds.

In fact, this method of preheating is very wrong, because the EFI engine is not like the carburetor engine, before reaching the working temperature, the fuel supply system can not work normally, and the phenomenon of unstable speed and stalling will naturally occur when driving reluctantly, so the carburetor engine is a last resort. However, if the EFI engine is preheated for a long time, it is not only unnecessary but also harmful. Shortening the warm-up time can extend the service life of the three-way catalytic converter, and can also improve the conversion rate of pollutants in the exhaust gas and save fuel.

Therefore, the correct approach is: after the engine starts, as long as it can maintain a stable speed, you can start the car, before the water temperature rises, properly control the speed, and wait for the water temperature to be normal after driving. During the run-in period, avoid slamming on the accelerator and avoid slamming on the brakes.

There are speed regulations in the initial stage of new cars, and domestic cars are generally stipulated within 40-70 kilometers per hour; Imported cars are generally stipulated in the initial 1000 kilometers, when the throttle is fully open, the speed does not exceed the maximum speed of 80, and it is required to pay attention to the engine tachometer and speedometer in use, so that the engine speed and speed are working at medium speed. Generally speaking, the engine speed during the break-in period should be strictly regulated.

Running a new car at full load will cause damage to the parts. Therefore, in the first 1000 km, domestic cars can not exceed 75 -80 of the rated load; Imported cars cannot exceed 90 percent of the rated load. In addition, try to choose a better quality road surface to avoid excessive vibration, collision or emergency braking, and reduce the load on the body and power system.
