We know that when a car is driving on the road, if you want to achieve high speed, you must step on the accelerator deeply, which means increasing the engine speed. At high speeds, the resistance increases, and the engine increases power output by increasing the speed.
The output power of the engine mainly depends on the displacement and speed of the engine. When the displacement is constant, the higher the engine speed, the greater its output power. When a car is driving at high speed, the higher the speed, the greater the resistance, and the greater the power the engine needs to output. With a certain displacement, more power can only be obtained by increasing the speed.
So, is it harmful to a small-displacement car to run at high speed? Not only does it hurt the car, it also hurts "money." Of course, this refers to the situation where you deliberately do not drive well. You can drive whatever you want while ensuring your personal safety! But when you should cherish it, you still have to cherish it. I have always preached the need to develop good driving habits. When you should go fast, you should go fast, and when you should go slow, you should really slow down. The higher the speed, the greater the amount of wear.
Of course, the amount of wear is not only related to the rotation speed, but also to the force on the friction pair. Under the same output power, friction loss is greater at high speeds and the amount of wear is also large. For example, when cruising at a speed of 60 kilometers per hour, you can use 4th gear, but you must use 3rd gear. At this time, the engine speed is high, the fuel consumption is high, and the friction pair wears out a lot. You say it will hurt the car but not the car!
