What Do Car Engine Power and Torque Mean?

[MorganFitz]

Car engine power refers to the amount of work done by an object per unit of time, which is a physical quantity describing the speed of work. Torque refers to the moment output from the crankshaft end of the engine. The relationship between engine power and torque is: power equals torque multiplied by angular velocity. An engine is a machine capable of converting other forms of energy into mechanical energy, serving as the device that provides power to a car, determining its power performance, fuel economy, stability, and environmental friendliness. Engines include: internal combustion engines, external combustion engines, jet engines, and electric motors. Their function is: to serve as the device that provides power to the car and as an energy conversion device, converting the thermal energy of gasoline into mechanical energy by burning and expanding gas in a sealed cylinder to push the piston and perform work.
