Several usage advice and maintenance tips are available during the running-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 in 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, to avoid overload: New car running at full load during the run-in period, will cause damage to the parts, so within 1,000 kilometers of the first drive, domestic cars can not exceed 75%-80% of the rated load, imported cars can not exceed the rated 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 a new car. Domestic cars are generally within 40-70 km/h, imported cars are generally within 100 km/h. When the throttle is fully open, 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 number, 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 the 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, and 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, the correct adjustment of the ignition system and oil supply system: This can solve the problem caused by the installation of speed limiter vacuum change, improve the economy of the run-in period. The maintenance running-in during the running-in period is completed Check the maintenance before entering the normal service period:    Check and adjust the tension of the fan and water pump drive belt; check and adjust the tension of the camshaft timing belt; adjust the valve clearance; check the tightness of the engine cylinder head screw; replace the engine oil filter; replace engine oil; add radiator Coolant; adjust ignition timing; remove air filter dust; adjust idle and idle mixer pedal clearance; check brake fluid volume to see if there is any leakage; adjust brake pedal travel; check hand brake lever and pull Cable stroke; Check and fasten wheel and hub nut connection; Check transmission and differential oil quantity; Check tightening torque of other key mothers; Check tightness of steering system clearance and leakage of lubricant oil, and if the free travel of steering wheel is appropriate . The running-in period is similar to the warm-up exercise of the athlete before the competition. This is the basic milestone for ensuring full contact, friction, adaptation, and shaping of the machine. During this period, it is possible to adjust the ability of the various components of the automobile to adapt to the environment and to abrade the projections on the components. After leaving the factory, the new car, although already running, but the surface of the parts is still rough. In addition, there are certain deviations and some hidden difficulties that are difficult to find during processing and assembly. Between the new parts and accessories, there are a lot of metal particles off, these metal particles not only make the wear between the parts worse, but also fall into the oil will make the quality of the oil drop, affecting the lubrication effect. Since the frictional resistance of new parts is greater than normal during operation, the fuel consumption will be relatively high.
