Shi Yun's car engine is the same oil. Why does the high-end gear rotate at a lower speed than the low-end gear? Isn't it the same speed to give the same oil? ?

This is the reason for the transmission ratio. The greater the transmission ratio, the lower the torque. The lower the transmission ratio, the higher the torque. This is the design of the gearbox. For example, if you climb a slope and use 1-2, it is easy to get up. If you use the fifth gear, you won't get up even if you step on the accelerator. Moreover, the engine design is not that simple. Doesn't mean how much gas you put in. In fact, what is the accelerator pedal of our vehicle? In fact, it controls the accelerator opening, and actually controls the intake volume, not the fuel injection quantity. The air intake determines the increase or decrease of fuel injection. In the middle, it is necessary to calculate the load, various altitude, intake pressure, intake temperature, knock feedback and other related data by computer, and then decide the fuel injection quantity, not how much oil you give, but how much oil the engine ECU decides. You only control the valve opening of the air inlet. Your reference should be speed. At the same speed, the low speed is higher than the high speed, mainly because the transmission ratio is different.
