The learning of the new car running-in period
Generally speaking, it is 1500-2000 km. The specific models are slightly different. We should strictly follow the calibration maintenance mileage of the on-board maintenance manual or the manual. First, the need to control the speed during the running-in period During the running-in period and the speed of the engine to control the initial 500 km of normal driving, the speed should not exceed 5000 rpm, do not exceed 501500 km, the speed should not exceed 6000 rpm, the speed should not exceed 8000 rpm before the speed should not exceed 8000 rpm. The speed should not exceed 80 during the running-in period, the engine speed should be changed frequently, the gears should be run-in, and the throttle should not be fixed at a certain speed. The purpose of this is to make the components work evenly, but not more than The maximum speed specified here should be emphasized here. The above data has not been scientifically justified. The landlord does not have such a professional level to demonstrate. These are based on years of experience and the practice of the old birds for many years. Each time you change the oil, you can pull the high speed in each gear position. The time should not be too long. It is enough for ten seconds. The purpose is to eliminate the running iron scrap when the carbon deposit and oil release are eliminated! 2. About the engine of the hot car during the running-in period Whether in the hot state or the cold state, after the ignition, the engine should have sufficient idle time to preheat, at least one minute to two minutes, in order to better flow the oil to all lubrication parts. . Third, change the engine oil There are many kinds of arguments on this topic. Some old birds have a view of 300 500 1000 1500 2000. It is necessary to change a lot of oil during the running-in period. This method is more secure. At most, it is more to spend more oil. At the very least, it will not damage your car. . However, some vehicle maintenance manuals write that the first oil change is 500 kilometers, the second oil change is 1000 kilometers, and the oil is changed every 2000 or 3000 kilometers later! At this point, I personally prefer the first statement, but I can make a change. Change to 300 800 1300 2000 After the running-in period, you can change the oil in four times. You can choose to use the fully synthetic motor oil during the running-in period. Why? As the name suggests, it is to be run-in. If you use fully synthetic motor oil, because of its excellent anti-wear properties, it will cause a more embarrassing situation, that is, the number of kilometers is enough, but the engine does not wear out! Use ordinary mineral oil! After the break-in period, the vehicle with high compression ratio can choose full synthetic motor oil. Here is a small tip. You can buy one bottle of the worst oil before changing the full synthetic oil. After draining the old oil, put the bottle into the machine. 2 to 3 minutes, then let go, then add fully synthetic motor oil! Fourth, the change of the engine during the primary running-in period Everyone should know that the motorcycle running-in period is 1,500 kilometers. There are many ways to change the oil in this 1500km. I suggest that you change the oil by 300km, 600km, 1000km and 1500km. Because the gears of the new car engine, the ejector pin or the chain work will produce waste, it is necessary to change the waste oil in time to drain the waste. And don't think about changing the oil for a few hundred kilometers and adding that cheap oil. This idea is not correct. No matter how many kilometers the car runs, as long as the engine is running, it is hot, it is on the oil. There is a lot of reliance, so when choosing oil, try to use the special engine oil that is sold with the engine at the place where the car is sold. Five, the choice of gasoline label This mainly depends on the compression ratio of the engine, and the instructions. Under normal circumstances, it is to look at the compression ratio of the engine. The compression ratio is 90 below 9:1 (but there are not 90 in many places now). 93 above 9:1 can be used for conditions above 10:1. Some cars have a compression ratio of even 12:1 or even higher. Sixth, the primary running-in period driving motorcycle Motorcycle driving during the running-in period is the biggest headache for novices. In fact, it is not necessary to be so demanding. After all, it is a mechanical thing, not so delicate. As long as you don't want to let the car out too much force, the speed of each gear should not exceed the limit of this gear. Motorcycles should try not to bring people and climb too steep slopes within 600 kilometers. Don't let the car eat vigorously. When you refuel, add 10 yuan for each time to reduce the weight of the car. The speed of the first 600 km is 10 km in the first gear, 20 km in the second gear, 30 km in the third gear, 35 km in the fourth gear and 40 km in the fifth gear. It is necessary to shift gears repeatedly from one gear to five gears. Cut back one file from the fifth gear. From 600 kilometers to 1000 kilometers, you can add weight to the car. It is better to say that you are not too fat, but try not to take people to climb steep slopes. The gear speed is maintained at 12 km in the first gear, 22 km in the second gear, 32 km in the third gear, 37 km in the fourth gear, and 45 km in the fifth gear. It is still necessary to shift gears repeatedly. After changing the new engine oil for 1000 kilometers, find a place with a good road and a small number of people. Use a five-speed pull-up high speed (do not exceed 70KG below 150cc, and do not exceed 80KG above 150cc). The guarantee time is about 30 seconds. Then still have to return to normal running-in state. The gear speed is maintained at 15 km in the first gear, 25 km in the second gear, 35 km on the third floor, 40 km in the fourth gear and 50 km in the fifth gear. Pull back a high speed at 1200 kilometers. At 1500 km, ride to the after-sales, clean the air filter (if it is a paper filter, you can only change it) and the Oil Filter , drain the oil and clean the engine (after cleaning the engine, be sure to dry the cleaning liquid in the engine) Add new oil).
