what is engine horsepower? the horsepower of a car refers to the unit of engine power. here's more information about horsepower:
1. horsepower is the working capacity of the engine per unit time: horsepower is a unit for measuring the performance of a car engine, and it is also an important parameter for measuring the performance of a car.
2. how to calculate car horsepower: horsepower is equal to torque times speed.
3. factors related to horsepower:
(1) discharge volume refers to the volume of gas exhausted by one revolution of the engine. the larger the displacement, 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.
