On the relationship between automobile throttle (throttle size) and power

1, 4000 rpm in neutral and 4000 rpm when floor oil is added, the power is different, and the latter is larger because the latter engine outputs more torque, while the neutral engine outputs less torque. (Engine output torque = load torque, the load determines the input,,, I will give you as much torque as you have resistance torque,,, similar to the hydraulic "load determines the pressure")

2. Throttle determines power, load determines maximum output torque, and power and maximum torque determine engine speed.

3. At the same speed, the power during gear shifting is higher than that in neutral for the same reason as 1.

4, manual transmission car, there is no rated power, only the maximum power, when the product of torque and speed is the largest, it is the maximum power.
