What does a 1.5-liter displacement mean?

[LeValeria]

1.5 displacement refers to the volume of fluid inhaled or discharged by the cylinder per stroke or cycle. Power and vehicle displacement: The larger the vehicle displacement, the higher the power. With a larger displacement, the energy released by the engine per unit time—that is, the conversion of chemical energy of fuel into mechanical energy—is greater, resulting in better dynamic performance. Vehicle displacement: It is an important parameter for measuring a car. Location: Some domestic cars do not have this type of car model number on their rear, but the displacement is usually indicated on the body or rear. Displacement classification: Mini cars have a displacement of ≤1.0L; compact cars have a displacement in the range of 1.0-1.6L; midsize cars have a displacement in the range of 1.6-2.5L; executive cars have a displacement in the range of 2.5-4.0L; and luxury cars have a displacement of >4.0L.
