What is the Difference Between 1.0 and 1.5 Displacement?
1 Answers
The two have different engines and displacements, which in turn affect power, fuel consumption, and subsequent maintenance. In congested areas, a 1.0-liter car has the advantage of being more fuel-efficient. At higher, more stable speeds, a 1.5-liter car performs better. A 1.0-liter displacement car can carry a weight of 1 ton, while a 1.5-liter car can carry 1.2 tons. The displacement of a car is an important parameter for measuring performance and is usually marked on the body or rear of the vehicle. Below are details about displacement and horsepower: 1. Displacement: Displacement refers to the energy released by the engine per unit time (converting chemical energy from fuel into mechanical energy). The working volume swept by the piston from top dead center to bottom dead center is called the cylinder displacement. If the engine has multiple cylinders, the sum of all cylinder working volumes is called the engine displacement. 2. Horsepower: Horsepower is another expression for power, which is defined in physics as the amount of work done by an object per unit time. It can be understood as the amount of energy produced by fuel per unit time. Therefore, power is simply a physical quantity that describes the speed of work—the higher the power, the more energy is generated per unit time, often resulting in a higher top speed for the car. Maximum power is usually expressed in metric horsepower (PS) or kilowatts (kW), where 1 PS = 0.735 kW.
