What is the relationship between engine throttle and speed?

The throttle of the engine is proportional to the output power of the engine. The concrete relationship is complex and cannot be expressed by accurate mathematical equations.

The rotational speed is related to the resistance, and the greater the resistance, the smaller the rotational speed.

f(x)=kx/n

K is a coefficient, there is no accurate value, and it needs to be obtained through experiments. This value is related to many parameters, such as throttle opening, resistance, temperature, oil pressure, fuel pressure, oil product, oil temperature, mildness, engine structure, etc. It is a constantly changing value.

N stands for assistance, for example, the greater the speed when driving, the greater the force acting on the engine.
