Many friends are discussing the issue of pulling the high speed, let me tell you what I know
What needs to be done after getting the new car is meticulous running-in. The first 100 kilometers are best to be completed under flat conditions without traffic jams, such as the 4th and 5th ring roads. This stage is rough grinding,pistonThe surface is still very rough and there is no mirror surface, the engine temperature is fast, the coolant must meet the requirements, and the car should be warmed up for 5 minutes in winter. At this stage, it is required to run smoothly and the speed should not exceed 100 kilometers. It is best to drive at 70 kilometers in 5 gears to avoid sudden acceleration and sudden braking. If the initial run-in is not good, the later run-in cannot make up.
In fact, pulling the high speed is plain, that is to speed up the running-incarThe mechanical parts of the mechanical parts make the surface of the mechanical parts smoother. During the running-in, the oil is relubricated, and the so-called oil will be generated due to the running-in of the parts. Therefore, if you have enough silver, it is recommended that you change it first. Engine oil, and then high-speed, and then change the oil after the high-speed is finished:) If you want to save money, then pull the high-speed first, and then change the oil:)
The first time to pull the high speed, it is best to drive 2500 kilometers-3000 kilometers, and not to pull in one gear, but to pull the speed in each gear! ! ! Keep each gear at 3000 rpm or 3500 rpm, and you can walk for about 10 minutes after hearing the low roar of the engine:), and after pulling the high speed, immediately change the oil! ! ! It's just crazy blindly pulling the high speed of the most gear, but the misunderstanding of pulling the high speed! ! ! ! !
Please use normal mode for automatic transmission. 100-1000 kilometers belong to the transition period,Rotating speedDo not exceed 4000 rpm, within 3,000 rpm is the best. If more than 100 kilometers, always pay attention to shift gears and run in.brakesystem. The speed of more than 1000 kilometers can be relaxed to 120 kilometers, and the speed should be controlled within 4000 rpm to 2500 kilometers. Pay attention to the use of gears 2 and 3 in the running-in of the gearbox, and do not blindly increase gears. 2, 3 gears run in well, and the noise will be greatly reduced at 3000 rpm.Over 2500 kilometers, do a maintenance and replace the new carOil filter, Replace the high-quality engine oil above SG, preferably SJ. The 2500---8000 km stage is mainly the gearbox running-in period. You can focus on the 3, 4, and 5 gear running-in period. For example, you can gradually try 3, 4, and 5 gears at 4000 rpm. Automatic transmission cars can occasionally try the sport mode. At the beginning, pay attention to the transition from 2400 to 3000 rpm in the first and second gears. After 10,000 kilometers, if you can have the opportunity to travel 110 kilometers-160 kilometers continuously for 500 kilometers, you will soon be able to taste the sweetness, that is, the noise of the vehicle will be significantly reduced. After 5 hours of continuous operation, the engine pistons and cylinders run-in is quite complete, forming a mirror-like fit, and the oil film and air tightness are greatly increased.
After 10,000 kilometers, you can try the limit speed if you have the conditions. It should be noted that you must have considerable driving experience before trying. In addition to responding to emergencies, there is also the technology to control the car. If you have the courage to know others, please be cautious! Safety first! ! !You have to be careful not to beCameratake a photo of:)
