What is the relationship between power and torque?
1 Answers
Power and torque are directly proportional. The following is an introduction to power and torque: 1. Automotive power refers to the work done by a car per unit time. The greater the power, the greater the torque, and the higher the pulling force of the car. Maximum power is commonly used to describe the dynamic performance of a car. Maximum power is usually expressed in horsepower (PS) or kilowatts (kW), with 1 horsepower equal to 0.735 kilowatts. Power is a physical quantity that indicates how fast an object does work. In physics, power P = work W / time t, and the unit is watt (W). 2. Automotive torque is the moment output from the crankshaft end of the engine. Under fixed power conditions, it is inversely proportional to the engine speed. The faster the speed, the smaller the torque, and vice versa, reflecting the load capacity of the car within a certain range.
