The formula for engine power is rotational speed multiplied by torque equals horsepower, which must be calculated using international standard units. The resulting horsepower is then multiplied by 735 watts to obtain the power, where 1 horsepower equals 735 watts. Below is a relevant introduction to engine power: 1. The concept of engine power: The work done by an engine per unit time is called the engine's power. Corresponding to indicated work and effective work, it is referred to as indicated power and effective power (output power), with the difference between the two called mechanical loss power. 2. The maximum power of an engine: The rotational speed at which an engine reaches its maximum power is called the maximum power speed. In automotive manuals, the unit for rotational speed is denoted as mn.
