Buying a new car at home is naturally a very happy thing. However, besides being happy, have you ever thought about this problem: Does the new car need maintenance during the run-in period? I think that most new car owners will think it is not necessary, but the answer for car beauty specialists is needed, and it needs careful maintenance.
The new car running-in period refers to the time when the new car is first set at a distance after the new car leaves the engine to run smoothly. The running range of the new car is generally between 1,000 km and 3,000 km. Generally speaking, the new car running-in period has the following characteristics:
1, driving faults: due to improper assembly of various components and other factors, the new car during the running-in period of more failures;
2. Large fuel consumption: In order to ensure that the new car runs in a small load during the running-in period, the carburetor car is equipped with a speed limiter. Therefore, it is extremely easy to cause the mixture to be too rich, thereby increasing the fuel consumption.
3, Lubricants are susceptible to deterioration: the new car in the run-in period, due to the rough surface of the parts and the small gap between the two parts, will make the temperature of the lubricating oil rise, at the same time, many metal shavings are falling into the lubricating oil, easy to make the lubricating oil oxidation And deterioration.
Here's something to note when using a new car during the break-in period:
1, start warm-up first: This is the case for the EFI car, before starting, you should first turn the key to the second block after 5-10 seconds, and then start, this is because the key door is open, the petrol pump Start work, adjust the oil pressure and fuel injection amount, so start it again after a few seconds to protect the new car engine;
2, avoid emergency braking: emergency braking will not only impact the brake system in the run-in, but also increase the impact load of the chassis and the engine, within the first 300 kilometers of travel, it is best not to emergency braking;
3. Avoid overloading: If the new car runs at full load during the running-in period, it will cause damage to the parts. Therefore, within 1,000 kilometers of the first driving, the domestic car cannot exceed 75%-80% of the rated load, and the imported car cannot exceed the rating. 90% of the load, in addition, to reduce the body and power system load, should choose a relatively flat road surface to avoid vibration, collision or emergency braking;
4, avoid running long distance: the new car running long distance during the run-in period, the engine will continue to work longer hours, easy to cause mechanical wear;
5. Do not drive at high speeds: There is a speed limit during the running-in period of new cars. Domestic cars are generally within 40-70 km/h, imported cars are generally within 1000 km/h. When the throttle is fully opened, the speed cannot exceed 80% of the maximum speed. , And pay attention to watching the engine tachometer and speedometer while driving, to ensure that the engine speed and speed in the middle speed work, under normal circumstances, the engine speed during the run-in period should be 2000-4000 rev / min;
6, the use of high-quality gasoline: the new car during the run-in period of use of gasoline can not be lower than the manufacturer's label, should try to add high-quality gasoline, do not add anti-wear oil, so as to avoid mileage is enough and insufficient running;
7. Do not remove the speed limit piece in advance: The speed limit piece is a throttling device installed between the carburetor and the intake pipe. The owner cannot remove it in advance. Wait for the new car to travel for 1,000 kilometers and then maintain it in good condition. It is removed;
8, timely shift: timely shift is to avoid high gear low speed and low gear high speed driving, do not use a gear for a long time, do not make the speed limit in each gear, in general, the various gear Speed ​​control in the top speed 3/4 range, specifically: 1 block 25 km, 2 block 40 km, 3 block 60 km, 4 block 90 km, 5 block 100 km;
9, correctly adjust the ignition system and oil supply system: This can solve the problem caused by the installation of speed limiter vacuum oil change, improve the economy of the run-in period.
In addition, in order to keep the new car mechanical system in its best condition and prolong its service life, it is recommended that new owners maintain your car in phases during the run-in period:
Within 1,100 km: The friction brake pad has not reached 100% braking effect, and the tire friction force is not enough. Therefore, when braking, apply more force than normal. In addition, in inspection and maintenance, exposed bolts and nuts should be tightened. Add fuel, engine oil, replenish the coolant, check the pressure of the transmission, front and rear drive axles, drive shafts, hubs, and tires, and check the braking capability of the lighting instrument, battery, and brake system;
2,100-500 kilometers: tire adhesion has not yet reached the best effect, the owner should try to avoid the emergency braking when cornering quickly, in addition, in terms of inspection and maintenance, at this time to replace the engine oil, and use kerosene to clean the oil pan, replace the oil Filter element and tighten the front and rear hub nuts;
3,500-2,500 kilometers: the owner should drive gently, the speed should not exceed 100 kilometers, and the speed should not exceed 2500 rpm;
4,2500-3500 kilometers: When the water temperature reaches the working temperature (water temperature pointer in the middle of the scale), the owner can increase the speed to the maximum speed or the maximum engine speed. In addition, if your car is a domestic car, you must replace the transmission , gear oil in the final drive and steering gear, and check the adjustment clutch pedal.
In addition to the correct driving during the break-in period of the new car, the owner should also strengthen the maintenance of the new car during the run-in period. Everyone should start from the following aspects:
1, the new car for the first time conservation: the first maintenance, body care is the most important, you should be in the professional car beauty care institutions for your car body waxing and other beauty maintenance, this is the key to car maintenance in the future, otherwise, such as improper maintenance , your car will have problems;
2, paint for the first time conservation: Although the new car paint no aging problems, but its from the factory to the owner to buy, the body paint on the contact with the air, acid rain, sand, etc., so timely and correct maintenance of your car is It is very important to carry out maintenance. If you are buying imported cars, you must first notice that car waxes contain paraffin, resin, and Teflon, and you cannot use wax or kerosene for wax removal. Professional waxing fluids should be used. , Or to a professional car beauty maintenance shop, ask the technician to help handle, as for domestic cars, most of the body using electrostatic spraying, the paint surface was shiny mirror, without waxing;
3. Clean the body for the first time: The body should be carefully cleaned for the first time. Otherwise, it will damage the oily part of the outer layer of the car, and make the car wash darker. You should go to a professional clean room and use a neutral detergent. The dirt on the surface of the car body is cleaned. In addition, dirt that cannot be seen with the naked eye, such as flying paint, gum, acid, alkali, etc., can only be removed with the detergent. The decontaminated clay can be removed by careful cleaning;
4, sealing glaze treatment: This is a new technology, sealing the glazed car without waxing in one year, clean water after cleaning with a clean suede cloth can be dry, after sealing the glaze, body anti-oxidation, anti-ultraviolet radiation, and Make sure the paint does not fade.
Finally, it should be noted that when the vehicle is driven to 3,000 kilometers, the owner should do a routine maintenance for your car, including changing the oil, changing the filter, measuring the cylinder pressure, removing the carbon deposit from the fuel chamber, and removing the speed limiting device. Adjust the engine idle speed, check the brake system, adjust the clutch pedal, tighten the front suspension, etc., so as to achieve smooth cooperation between all parts of the vehicle, so that it can perform its best performance.
