How long is the run in period and what is the fuel consumption?

The run-in period of the car needs to be about 3000 kilometers, and the fuel consumption is still relatively high during the run-in period.

The general run-in period is 3000 km. This value is not absolute.

The fuel consumption of new cars is generally low.

Fuel consumption is a comprehensive value, which is related to many factors such as the engine, engine displacement, driving habits, road conditions, etc.

I generally check the fuel consumption of a certain car, all with the help of third-party software, from the bear fuel consumption.

Go to the gas station to fill up the fuel tank, jump the gun shall prevail, and then reset a vehicle mileage, after driving 100 kilometers, come and fill the fuel tank to jump rob, see how many liters of fuel are added, and a simple division can get the average fuel consumption, which is recognized as a more accurate method than the dashboard.

Instantaneous fuel consumption: that is, the fuel consumption of a certain moment of the vehicle, when the car is driving, it is displayed as a liter 100 kilometers, and when the car is stationary, it is displayed as a liter hour, so the instantaneous fuel consumption calculation is very complicated, and it is high and low, and basically has no reference value.

Average fuel consumption: The fuel consumption we usually refer to is the average fuel consumption, which is generally calculated in 100 kilometers, also known as 100 kilometers of fuel consumption. Generally speaking, it is the last 100 kilometers, the car consumes a few liters of fuel, but there are also cats in the middle, such as this 100 kilometers of the period, the vehicle starts but does not drive, and the fuel consumption generated by idling is not calculated by many cars.

Generally 1-2 oil heights are normal. The fuel consumption of a new car during the run-in period is not a fixed value. With the same displacement, a heavier car will definitely have higher fuel consumption.

The fuel consumption of an automatic transmission car is higher than that of a manual transmission car. The driving environment during the break-in period is also one of the important factors affecting fuel consumption. Fuel consumption is certainly not the same as driving on a highway and in a congested city.

Attached: New car run-in period strategy:

1. Don't be too high

During the run-in period, the engine is not completely run-in, and it is necessary to avoid the situation that the engine speed is too high, which will cause great wear to the engine and is not conducive to the normal run-in of the engine.

2.Hot up before departure:

Whether it is a new car or an old car, it is recommended that the owner warm up the car in time, especially the car during the run-in period. It is more necessary to warm up the car correctly, so that the engine has a full run-in during operation. Generally, the car can be started within a minute.

Pay attention to the first few minutes of running, don't accelerate sharply, turn on slowly, and then accelerate slowly after the water temperature is normal.

3.Avoid cruise control:

When the car is driving at high speeds, avoid cruising at a fixed speed. If the speed is kept constant for a long time, the temperature of all the parts in the engine can be too high.

When the new car leaves the factory, due to the machining accuracy of various parts and other reasons, the moving parts of all parts in the car have not been run-in, so it must be used with caution, otherwise it will aggravate the damage of the parts and bring hidden dangers to the future. Fuel consumption during the run-in period is not allowed, because it is related to personal driving habits and road conditions, and then it depends on what kind of car it is. Generally only 7-8 oils.

Run-in rules for new cars within kilometers: (1) Do not drive at full speed. (2) Generally, it is not allowed to drive at a speed of more than 100km h, and (3) Avoid high-speed driving in each gear.

Running-in rules for vehicles driving Chunqixian 1000 15000 km: gradually increase to the maximum speed or run at the maximum permissible engine speed. 2.

After the run-in period, it should be noted that: (1) When driving a car with a tachometer, change to the adjacent high gear, and when the pointer reaches the red indication zone at the latest, the maximum allowable engine speed for a short period of time is 5,500rpm. The maximum speed allowed for each gear is:

The first gear is 40 kmh, the second gear is 65 km/h, the third gear is 100 kmh, the fourth gear is 135 kmh, and the fifth gear is 165 kmh. (2) Avoid the engine running at unnecessary high speeds, and switch to high gear as soon as possible is conducive to fuel saving and noise reduction. (3) The engine speed should not be too low when driving.

Only when the engine is working hard does it shift to low gear. (4) The rotational speeds and rotational speeds listed in the manual are for normal temperature engines only. When the car is cold, whether in neutral or other gears, don't let the engine work at the highest speed.

If the novice is not familiar with acceleration and deceleration during the run-in process, and the driver suddenly accelerates to stop, the fuel consumption will be 2 to 3 times higher than that of driving at a constant speed. In the process of normal driving and running-in, the fuel consumption is generally about 1-2 oils.

The increase in fuel consumption is a multifaceted factor that has not been solved.

In general, the optimal "economic speed" for a new car is 60 to 90 kilometers per hour. On the highway, it is better not to exceed 100 kilometers per hour for a four-cylinder car. If the speed is 120 kilometers per hour, it will consume 20% more fuel than the speed of 100 kilometers per hour.

Tires are also afraid of insufficient tire pressure. The data shows that as long as one less 40kpa air tire is installed, the tire life will be reduced by 10,000 kilometers, and the total fuel consumption of the car will increase by 3%. If the tire pressure is reduced by 30%, the car will increase fuel consumption by 5%-10% when driving at a speed of 40 kilometers per hour.

Therefore, car owners should pay more attention to tire pressure adjustment in different situations to avoid excessive fuel consumption.

Road conditions include whether the road is smooth, whether there is friction, uphill and downhill, and whether the road is congested. Generally, in the section with many curves and frequent sudden braking, the fuel consumption will definitely be much higher. If you can only walk a few kilometers in an hour during the morning and evening rush hours, then in this severe traffic jam, fuel consumption can be more than three times that of a smooth traffic.

Because the new car is likely to have errors in the whole assembly process, the machining accuracy of the parts is likely to be poor, so it needs to be driven within the corresponding mileage, which can play a very important role in the performance of the car and prolonging its service life. The run-in period of the whole vehicle is usually about 2000 kilometers, which is divided into the run-in period of new tires, the run-in period of the engine and the run-in period of the gearbox. Among them, the most important is the run-in between the engine and the gearbox.

Initial stage (new tire running-in): 0-500 km, run-in between tires and the ground, the speed can not be higher than 2200rpm mid-term (engine run-in): 500-1000 km, mainly including piston and cylinder ballast sleeve, connecting rod and bearing pad and other grinding brakes.

The speed can be maintained at 60-70 km/h, the speed can be increased to 90-100 km/h, and the speed can be kept below 2500 rpm; Middle and late stage (transmission running-in): 1000-2000km, the run-in between gearbox gears can be increased to less than 120kmh, and the speed cannot be higher than 3,000rpm. During the entire run-in period, the car must gradually control the speed and speed, and it is not allowed to drive violently, slam on the accelerator, brake sharply, and slam the direction.

Usually the fuel consumption during the run-in period is relatively high, 1-2 oil higher than normal, mainly because the middle parts of the new car have not reached the best working conditions, and it is not very smooth, the friction resistance is large, and the driving is hard, so the fuel consumption is more. However, the vertical hail is coarse, and after the run-in period, the fuel consumption will be reduced. Millions of car purchase subsidies.

The fuel consumption is high during the run-in period.

The run-in period of the new car is generally 1000 1500 kilometers, which is the basic mileage to ensure the full contact, friction, adaptation and finalization of the parts. During this period, it can be adjusted to improve the slag ability of each part of the car to adapt to the environment, and grind off the protrusions on the parts. The quality of the car run-in will have an important impact on the life, safety and economy of the car.

After leaving the factory, although the new car has been run-in, the surface of the parts is still rough. In addition, there are certain deviations in processing and assembly and some hidden dangers that are difficult to find. There are many metal particles falling off between new parts and accessories, which not only aggravate the wear between parts, but also reduce the quality of the oil after falling into the oil, which affects the lubrication effect.

Since the new parts have more frictional resistance during operation than in normal times, the fuel consumption will also be higher.

The run-in period is more fuel-intensive, and it will be saved after the first guarantee of the run-in period. The viscosity of the oil used during the run-in period is higher than that of ordinary engine oil, which is conducive to protecting the engine, but the flow resistance is large, so it costs oil.

How to save fuel during the run-in of a new car:1. Develop good driving habits during the run-in period.

According to the normal rhythm of running-in, the most fuel-efficient driving method is generally the best running-in method. For example, when driving at a constant speed, the body should not be overloaded, avoid driving for a long time, and the engine speed should not be too high when used. In general, the rotational speed should not exceed 3000 rpm, and if it is automatic, it should not exceed 3500 rpm.

2.The right oil also saves fuel. There are two aspects to choosing fuel-efficient oil, one is the choice of oil, and the other is the choice of gasoline.

If pure engine oil or low-quality fuel is not used, it can cause fatal injuries to the vehicle. The fit between the new engine components is rough and requires an oil of the right viscosity. In general, cars do not need to change their oil when they leave the factory.

However, due to some fouling during the initial run-in of the new engine and changes in the viscosity of the oil during the initial run-in, the manufacturer required that the oil must be changed during the first warranty period.
