What is Horsepower in Cars?

[StMorgan]

Here is an introduction about horsepower: 1. Introduction: Horsepower is a commonly used unit of power measurement in engineering technology. It was proposed by James Watt. 1 horsepower is approximately equal to 735 watts. Generally, it refers to metric horsepower rather than imperial horsepower. 2. Factors affecting car horsepower: Displacement, the volume of gas expelled by the engine in one revolution. It can be roughly understood as cylinder volume * number of cylinders. The larger the displacement, the more fuel it consumes, and the greater the horsepower. Compression ratio, the volume of the cylinder at bottom dead center divided by the volume at top dead center. According to Moore's Law, the higher the compression ratio, the greater the horsepower. It does not increase fuel consumption. Turbocharging, which increases intake pressure, enhances the engine's maximum power.
