What is engine horsepower? The horsepower of a car refers to the unit of engine power. Here is more information about horsepower:
1. Horsepower is the working capacity of the engine per unit time: horsepower is a unit to measure the performance of a car engine, and it is also an important parameter to measure the performance of a car.
2. How to calculate car horsepower: Horsepower is equal to torque multiplied by speed.
3. Factors related to horsepower:
(1) Displacement volume is the volume of gas eliminated by the engine in one revolution. The greater the displacement volume, the greater the fuel consumption and the greater the horsepower.
(2) The compression ratio is the volume at the bottom dead center of the cylinder divided by the volume at the top dead center of the cylinder. The greater the compression ratio, the greater the horsepower.
(3) Turbocharging increases the intake pressure and increases the maximum power of the engine.
