Since the beginning of this year, driven and encouraged by national policies,carSales are booming all the way, and many people have joined the car owners. For their first car, these new owners took great care. In fact, the use of the new car's running-in period is very critical to the future performance of the entire vehicle. So how can a new car pass the running-in period safely, what should be paid attention to during driving, and how should it be maintained? Today we first talk about the driving requirements during the break-in period.
The new car has to run for a 3,000-kilometer run-in period, which is the basic mileage to ensure full contact, friction, adaptation, and shaping of the parts. In order to maintain the best condition of the mechanical system and prolong its service life in the future, you must drive carefully during this period.
Phased maintenance
First of all, for 100 kilometers, the new friction brake pads have not yet reached 100% braking effect.brakeThere should be advance, especially within the first 200 kilometers,tireThe friction is not enough, so you need to use more force when braking than normal.This is also included in the newly renewedtireOr new brake pedal.
Secondly, in the first 500 kilometers, the new tires have not yet reached the best adhesion, so emergency braking should be avoided when fast turning.
Again, the driving speed does not exceed 100 kilometers per hour,Rotating speedNo more than 2500 revolutions.
Then, in the first 2500-3500 kilometers, the water temperature has reached the working temperature (the water temperature pointer is half of the scale), and it can be gradually increased to the maximum speed or the maximum engine speed.
Finally, after a routine maintenance of 3000 kilometers (using the original engine oil), all the moving parts in the car will be in a smooth motion state, which can give full play to the best performance of the car.
Don't drive in high gear for a long time
High speed can also increase the load on the engine and transmission components. Therefore, the vehicle speed should be controlled within the specified range. From 1000 kilometers to 1500 kilometers, the engine speed and vehicle speed can be gradually increased to the maximum acquiescence speed. It is not allowed to drive in the first gear or high gear for a long time; do not allow the vehicle speed to reach the limit in each gear, and the hourly speed of each gear should be controlled within three-quarters of the top speed, generally: 1 gear 25 kilometers, 40 kilometers in second gear, 60 kilometers in third gear, 90 kilometers in fourth gear, and 100 kilometers in fifth gear. Do not practice your car skills and run wildly at this time.
"Leave first and then brake" during the running-in period
Since the parts are still in the running-in period, excessive load and high speed will aggravate the impact on the parts. In addition, during the running-in period, the car should also be careful not to make an emergency brake as much as possible, and pay attention to preheating when starting a cold car. Strive to achieve slow start and slow stop.
Warm up at the start, and the brake is separated and closed. Try to avoid emergency braking. The hand brake must be completely released during driving, because the brake pads of the new car are thicker and the gap between the brake drum and the brake drum is small. If not completely released, the brake pads and brakes will be caused The drum is damaged by friction for a long time, even causing accidents.
It should be noted that the "first release and rear brake" approach is to protect the engine during an extraordinary period of running-in, and in an extraordinary situation (emergency braking), it must not be used as a good habit for a long time.When the vehicle has passed the "conservation" period, fromclutchIn terms of maintenance, it should be “brake first and then leave”. When learning to drive, many novices are afraid of stalling and do not forget to pedal the clutch. If they want to slow down, they must first step on the clutch. Also for the convenience of shifting, the clutch does not leave the foot. Braking and shifting in this way may make the car drive more smoothly for novices, but it will cause considerable damage to the clutch.
In addition, the gears must be shifted frequently. The running-in vehicle should be gradual when driving, start with the lowest gear, gradually increase gears, never use high gears to drive at low speed, or low gears to drive at high speed, and shift gears frequently. Do not use one gear to drive for a long time. (Car Help Network)
