What is the relationship between displacement and horsepower?

[SanAnna]

Normally, displacement and horsepower are directly proportional. The larger the displacement, the greater the power, and consequently, the higher the horsepower. Below are the relevant introductions to displacement and horsepower: 1. Displacement: Displacement refers to the energy released by the engine per unit time (i.e., converting the chemical energy of fuel into mechanical energy). The working volume through which the piston moves from the top dead center to the bottom dead center is called the cylinder displacement. If the engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement. 2. Horsepower: Another expression for horsepower is power. The physical definition of power is the amount of work done by an object per unit time. It can be understood as the amount of energy generated by fuel per unit time. Therefore, power is merely a physical quantity describing the speed of work. The higher the power, the more energy is generated per unit time, and often, the higher the maximum speed of the car. Maximum power is generally expressed in metric horsepower (PS) or kilowatts (kW), where 1PS=0.735kW.
