Generally speaking, what is the appropriate distance for the run in period of a new car?

The running-in period is to grind the mating clearance of the friction parts to a reasonable range within a period of time in order to achieve better lubrication. If the engine speed is too low during the running-in period, the impact of the crankshaft connecting rod bearing is greater, and the cylinder wall is easy to be strained if the speed is too high, causing early wear, so the running-in period should refer to the engine speed rather than the vehicle speed, the gasoline engine speed is between 2000 and 3000 rpm, and the diesel engine is between 1000 and 2000 rpm.

Does the current new car still need to be run-in? Regarding the run-in period of a new car, you may have heard a lot of such words: the accelerator and brake should be gentle, not too fast, do not go at high speed, and try to keep moving forward at a constant speed, otherwise it will hurt the vehicle engine and so on. >>>More

Curtain width = a = window width + meters.

The width of the addition is 25 30 cm on both sides of the window, js generally tells you to add 30 cm each, but according to my observation, 25cm is enough (25 cm is enough for a Roman rod, the cloth is 20 cm wider than the window frame, and 5 cm is the head of the Roman rod). If the room is not square and has a hypotenuse, you should pay attention to whether it can be added to 25cm, I have a hypotenuse in my house, and the head of the Roman rod with 25 cm cannot be installed. It should be noted that because the balcony window has longitudinal edges on both sides, there is no need to add meters. >>>More
