What should I pay attention to during the run in period of a new car?

Be careful not to brake suddenly, as it will shock the braking system. Do not run long distances, which is easy to cause wear and tear of the parts. Don't change the oil too soon, some car factories add powerful abrasives.

Kilometers, maintenance issues. When the new car is in the run-in period, it should be maintained according to a certain number of kilometers. At the same time, we must pay attention to maintenance problems and insist on maintenance in the 4S store.

In the run-in stage of the new car, it is necessary to carry out maintenance in time, and we need to carry out timely inspection and maintenance of the vehicle after reaching a certain number of kilometers according to the manufacturer's recommendations on the vehicle manual.

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.

Precautions for the run-in period 1Try not to brake urgently: Emergency braking not only impacts the braking system in the run-in, but also increases the shock load on the chassis and engine, and it is best not to brake urgently during the first 300 kilometers.

2.Don't overload: If the new car runs at full load during the run-in period, it will cause damage to the parts.

Therefore, at 1000 mm of the first run.

It is necessary for the driver to know the expertise of the car. There are too many people driving now, but there are too few people who really know how to drive. Understand some professional knowledge of cars, learn the knowledge of using cars, truly grasp the rules of car use, and improve the communication ability between cars, which can not only save gasoline for car owners, but also allow car owners to maintain their cars while driving, so that cars can "make the best use of things" and "prolong life".

Put forward the core idea of combining "car love and human love". So what are the precautions during the run-in period of the new car?

1.Avoid speeding.

The speed limit of high-speed new cars in the starting stage is regulated, and domestic cars are generally within 40-70km h; It is generally stipulated that the speed of imported cars in the first 1000 kilometers when the throttle is fully open can not exceed 80% of the maximum speed, and the engine tachometer and speedometer need to be observed when used, so that the engine speed and vehicle speed can run at medium speed.

2.Avoid removing the speed limiter in advance.

In the early days, the vehicle was equipped with a speed limiter before leaving the factory, which was a throttling device installed between the carburetor and the intake pipe. The pilot should not take off in advance, but should take off after the initial speed of 1000 km, taking into account the initial maintenance situation. At present, there is generally no speed limiter on the vehicle, and the driver has full control over the speed.

3.Avoid emergency braking.

Emergency braking will not only impact the braking system during the run-in process, but also increase the shock load on the chassis and engine, so do not use emergency braking for the first 300 km. If there is an emergency, you should press the clutch pedal as much as possible to reduce the impact on the engine.

4.Do not use non-standard oils.

The oil used in a new car should not be lower than the label specified by the manufacturer.

5.Avoid long journeys in your new car.

It will increase the continuous working time of the engine and increase the wear and tear of parts. If you need to run long distances, it is recommended to stop for half an hour every 200 km.

6.Avoid careless driving maneuvers.

After starting, the car should be heated on the spot and then started after the water temperature reaches the starting temperature. When driving, you should choose a good road surface, keep driving at a moderate speed, do your best to avoid sudden acceleration and sudden braking, keep the throttle small and light operation, and pay attention to the sound and temperature of the engine at any time.

7.Avoid exceeding the rated load.

Running a new car with a full load or a newly repaired car with a full load can damage machine parts. Therefore, in the first 1,000 kilometers, domestic cars cannot exceed 75%-80% of the rated load; Imported cars cannot exceed 90% of the rated load.

8: Avoid not changing gears in time.

When driving, you should shift gears in time. Do not use high-speed low-gear or low-speed high-speed, and do not use one gear for a long time.

Millions of car purchase subsidies.

Before the assembly of the car, each running part is processed separately, and there are geometric deviations on the surface of the parts, that is, the accuracy will not fully meet the requirements of the design, and there must be some tolerances, so after assembly, some running parts will be in direct contact locally, and the lubricating oil is difficult to rub the surface, resulting in early wear. The run-in period is to grind off the part of direct contact within a certain period of time, which is called the run-in period. The run-in period of new cars is generally 1000-3000 kilometers.

The break-in period is not just about the engine being run-in.

When it comes to the run-in period of the car, many people think of the run-in of the engine, which is not comprehensive. There are two key purposes for the run-in of a new car: the first is to achieve the run-in of people and vehicles, and the second is the run-in of the contact friction parts of the vehicle.

The running-in of people and vehicles can be said to be three days and three nights, so I won't go into detail here. If you need it, you can find a time to dedicate an article to this matter. The mechanical run-in of the vehicle is mainly along two main lines, one is the power line (engine):

Power and lubrication systems, transmission systems. follower steering system, etc.; The other main line is the braking system: the smooth contact between the brake oil circuit, the brake disc and the brake disc.

6 major contraindications during the run-in period.

1. 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.

2. Avoid excessive load: If the new car runs 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. Avoid running 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 the parts.

4. Avoid high-speed driving: there is a speed limit during the run-in period of the new car, which should generally be controlled within 100 kilometers per hour, 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 it works at medium speed. Under normal circumstances, the engine speed should be 2000-4000 rpm during the run-in period.

5. Avoid premature oil change: 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 running-in, so the oil during the run-in period only needs to be changed according to the time specified by the manufacturer, and should not be replaced too early.

6. Avoid starting without heating the car: the new car must be warmed up before starting, the so-called preheating is actually to give the engine a full lubrication time, especially turbocharged models, must be preheated before starting, and the lubrication time should be at least one minute or more.

Hello, the number of kilometers during the run-in period should be controlled within 3500 kilometers as much as possible, and the speed of the vehicle should not exceed 100 kilometers per hour. The purpose of pulling the high speed is: 1. The continuous high flow of fuel injection washes away the gum accumulated by some fuel injection nozzles, so that the oil injection atomization is improved.

2. The non-stubborn carbon deposits inside the spark plug and cylinder are removed due to full combustion. In fact, the role of pulling high speed is not only the above two points, but also the suspension of high speed, shock absorption, rotation mechanism, gearbox and even tires have certain benefits, of course, the most important thing is the engine. It is recommended that you pull the high speed after the first guarantee, and keep the engine speed at 4000-4500 rpm under half load or full load in the middle and high gear in manual mode, and run for 5-10 minutes at 4000-4500 rpm in the middle and high gears, for the lower the gear, the lower the gear, the corresponding time should also be shortened, such as the first gear to choose to pull 1-2 minutes, the second gear to 1-2 minutes, the third gear to 3-5 minutes, the fourth gear to 3-5 minutes, the fifth gear to the sixth gear 5-10 minutes, each cycle interval of 10-15 minutes, cycle operation to drive 50-100 kilometers, At this time, pay attention to the speed and safety of the high-end level, but when reducing the engine speed.

What are the precautions for a new car?

1.Whether it's a new car or an old car, the car needs to be warmed up for starting, and it's very necessary. Because the temperature of the engine that has just started is low, the lubricating oil in each part is not in place, and the parts that are in contact with each other will not be fully lubricated, resulting in the loss of parts.

In this case, friends who love both environmental protection and cars will be entangled, because after starting the engine, the vehicle will begin to produce exhaust gases (more than normal driving emissions), but the vehicle must get a certain "warm-up". However, if a long time of "warm-up" will not only cause a lot of carbon deposits in the engine, but also is not conducive to environmental protection, so I recommend that you start the vehicle in about 10 seconds before you can go, which is equivalent to the time to fasten your seat belt and tidy up your clothes.

2.Avoid overloading. New cars during the break-in period cannot exceed 80% of the rated load.

3.Avoid long-distance driving and high-speed driving. Long-distance travel also means that the engine works continuously for a long time, which is a load on the parts that still do not "communicate" well inside the engine, which will directly affect the coordination between the parts, which is not conducive to the long-term use of the engine.

4.Use better quality fuel. In fact, whether it is a new car or an old car, they cannot use fuel lower than the manufacturer's specified mark (the label is generally on the fuel tank cap).

This is still in the mileage is enough to run-in. The suggested method is to put the gear in low gear first, and then let the engine speed increase to the middle and high sections, hold for 20-30 seconds, not too long, and the speed should not be too high. Then, let go of the throttle to actively reduce the speed and rev of the car, and then each gear is used in this way to carry out the appropriate gearbox, you can switch to manual mode, and then according to the above method, each gear for the braking system needs to run in the period, do not slam on the brakes to make the brake pads of the new car to achieve a better match clearance.

5.Shifting gears needs to be timely, and this is mainly for novices and friends who use manual transmission models. Timely gear change is to avoid the situation of low rpm in high gear and high rpm in low gear, which is not good for the long-term use of the engine.

Don't use one gear for a long time, upshift when it's time to upshift, downshift when it's time to downshift, and don't switch every time you reach the top speed of the gear.

6. Do not brake in an emergency from time to time. This is closely related to the running-in and will also affect the safety of the car in the future. Whether it's a new car or an old car, if emergency braking can be avoided, try to avoid it, because every emergency braking will damage the braking system and increase the danger.

In order to avoid emergency braking. In other words, try to make it as slow as possible to stop the car while making it safe.
