New car break in problems! Analysis of new car running in skills

There is a misunderstanding in the run-in of new cars, thinking that you can't run at high speed, but it's actually wrong.

For example, even if the speed is only 50 kilometers, if the gear is in the first gear, the damage to the car is great, but if it is in the sixth gear, even if the speed reaches 130 kilometers, the damage to the car is not great. Generally, the car manufacturer requires that when the new car is running-in, the engine speed should not exceed 70% of the red line area of the tachometer, which is safe in this range and has no damage to the car. In addition, the precision of today's engine manufacturing is quite high, and it is no longer a concept from the so-called run-in engine with high drivers a few decades ago.

Regarding the run-in of the new car, there is another thing that needs to be paid attention to, that is, the run-in of the braking system, transmission system, and suspension system.

It doesn't have a big impact, the important thing is not to pull too heavy and not to use a gear for a long time to change it at any time This is good for the pressure box I hope it will help you.

In fact, 5,000 kilometers is before the first insurance (the mileage of each brand is different) after the high-speed driving.

At least the first 2000 kilometers are required, and before the first 90 kilometers are not more than 90 kilometers per hour, start smoothly, and do not slam on the brakes.

Why run in?

A car is a mechanical product in which many mechanical parts work together. Due to the limitation of machining accuracy and other reasons, the cooperation between them has not yet reached a very smooth state. A new car that has just left the factory, or a new car that has just been overhauled, needs to be run-in.

Running-in is the friction of the occlusal part between the parts, so that the occlusal surface is smoother and fits more closely with each other. With a better run-in vehicle, the overall condition will be improved, such as the vehicle is more dynamic, more fuel-efficient, less noisy and more agile than before.

Automobile running-in not only includes engine running-in, but also sells acres including transmission running-in, brake running-in, etc. Automobile break-in is the general term for these main components.

How do you run in?

Since the running-in is to make the surface of the parts with processing marks more delicate through the mutual "polishing" between mechanical parts, so as to achieve the purpose of smoother coordination between them, it is necessary to make the mechanical movement as light as possible during the running-in process, and all occlusal parts should be polished. Specifically, it should be noted that Nakamori:

1.The start is smooth and the acceleration is slow.

Be gentle and start steadily. After the engine is ignited, the car should be fully warmed up and then started slowly to avoid violent driving phenomena such as sudden acceleration, sudden braking, and high-speed turning. Start in low gear and accelerate slowly. After 1 km, it is best to change to a high gear.

2.Do not let the engine rev too high.

Generally, the automobile manufacturer will mark the maximum driving speed of the car during the run-in period, and the maximum speed limit during the run-in period shall not exceed 2 3 of the maximum speed of the car. However, this method is not accurate, because sometimes although the speed does not exceed the limit, the engine speed is too high due to improper gear control, so it is more scientific to use the engine speed to measure. In general, the maximum speed of a gasoline engine during the break-in period should not exceed 2000 rpm, while the maximum speed of a diesel engine should be 1000-1500 rpm.

If the rev speed is too high, the load on the engine will increase, causing a lot of damage to the engine.

3.Do not drive heavily loaded.

During the break-in of the car, excessive load can also damage the car, so the lighter the car during the break-in, the better. It's best not to pull several people around at once, and not to load heavy loads.

4.Don't drive it for too long.

When a new car starts to run in, it usually takes a few hours to stop and give the car a break. Don't let the car run all day, even long distances.

5.Do not save the gear for a long time.

When driving, you should change gears in time so that every gear can run in, and you have to run in all kinds of road conditions. Vehicles equipped with automatic manual transmissions should operate in both manual and automatic modes.

6.Try to avoid emergency braking.

Emergency braking not only impacts the braking system during break-in, but also increases the impact load on the chassis and engine, so do not use it for the first 300 kilometers. If there is an emergency, try to press the clutch first and then the brakes to reduce the impact on the engine.

Millions of car purchase subsidies.

Principle of driving during the run-in period:

2.Run-in in the urban area: slip the edge and sink to the bottom, and pick up slowly.

3.The run-in period should be half loaded, especially for the first 1000 kilometers, and it is best to have no more than 2 adults and one child in the car;

4.Check at any time during the run-in period: coolant, oil dipstick, tire pressure, driving computer;

5.It is not recommended to use the air conditioner for a long time during the run-in period, because the air conditioner will occupy the engine, it is best to use it only when driving smoothly;

<> "Precautions during the run-in period:

1. Try to be as slow as possible, not fast. The initial driving speed of the new car should be controlled within 60-80 km/h.

2. Remember routine inspections. New cars must be routinely inspected to identify and eliminate problems in advance to prevent future troubles. Check oil, water and gas (engine oil, brake fluid, battery, cooling water and tire pressure).

If a shortage is found, it should be replenished in a timely manner. If it is found that there is running, running, dripping and leaking, it should be repaired in time. Second, check whether there is abnormal noise in each part of the car, and repair it in time if abnormal noise is found; Third, check the dashboard of your car.

If the alarm light is on or the computer prompts, it should be repaired in time.

Contraindications for the run-in period:

1. Avoid emergency braking.

Emergency braking not only affects the break-in braking system, but also increases the shock load on the chassis and engine. It is better not to use emergency braking for the initial 300 km.

2. Avoid overloading.

If a new car is run with full load during the break-in period, the parts will be damaged. Therefore, in the first 1000 km, the general load should not exceed 75%-80% of the rated load.

3. Avoid running long distances.

When a new car runs for a long time during the break-in period, the continuous working time of the engine increases, which can easily cause wear and tear of parts.

4. Avoid driving at high speeds.

There is a speed limit during the break-in of the new car. Domestic cars are generally within 40-70 kilometers and hours, and imported cars are generally within 100 kilometers and hours, and the speed of the vehicle cannot exceed 80 percent of the maximum speed when the throttle is fully open. While driving, pay attention to the engine tachometer and speedometer to make sure they work at moderate speed.

Under normal circumstances, the engine speed should be 2000-4000 rpm during the run-in period.

5. Avoid premature oil changes.

The initial oil of the car is a special lubricating oil in the running-in stage. It requires low viscosity, good heat dissipation, excellent cleanability, and oxidation resistance. Some car factories also add abrasives that help with the break-in.

Therefore, the oil in the run-in phase can only be changed according to the time specified by the manufacturer and cannot be changed prematurely.

6. Avoid starting without a hot car.

A new car must be warmed up before it starts. The so-called warm-up actually gives the engine enough lubrication time, especially for turbocharged cars, which must be warmed up before starting, and the lubrication time must be less than a minute or more.

Now in the new car, the engine run-in is not as strict as before, and the engine of Kaiyue has been very durable and stable, and the run-in period mainly grasps the following essentials:

1. Avoid sprinting and stopping, and avoid idling for a long time!

2. Within 1500 kilometers, try not to exceed 80 mph.

4. Try to let each gear be run-in, if it is used in urban areas, it is rare to use 5 gears, then you need to run in five gears at high speed after the first guarantee. Pay more attention to the changes in the various liquid levels inside the cabin, and observe whether there is any leakage under the car in the morning before starting the vehicle. The warm-up time is reduced to 800 rpm, and the first 1 to 2 kilometers should be driven slowly until the water temperature reaches a normal state, and you can drive normally.

5. 4000 to 4500 kilometers as the first insurance!

1. Don't be fully loaded.

2. Don't brake with a big foot on the accelerator or brake on a big foot.

3. The speed is not more than 80

4. Try not to climb the slope.

Have you ever run in for your new car?

Amankara. Regarding your question, although the new car has been cold-run in the Senli brother factory, the sports friction parts of each part still need to go through more than 3000 5000 kilometers of running-in in order to establish a good cooperation relationship. The following points need to be paid attention to during the run-in period of a new car:

1.The speed of the high-speed engine should not be too high during the run-in period, and it should not exceed 3500 rpm, and the speed is not very important. 2.

There should be a process of warming up the car during the cold start, and driving on the road after the water temperature changes, generally about 3-5 minutes. 3.The load must be reduced according to the load regulations of the model, and it is advisable not to exceed 70% of the specified load capacity.

4.The impact damage of the engine, braking system and chassis of the new car should be dealt with in advance, and the gear should be reduced. 5. Avoid sudden refueling and braking, and try to maintain a constant speed.
