What does an engine displacement of 1.490L mean?

[VanHazel]

1.490L refers to the engine displacement, which is a naturally aspirated engine. Natural aspiration is a type of car intake system that relies on atmospheric pressure to force air into the combustion chamber without the use of any supercharger. Introduction to Displacement: Simply put, it is the total volume of the engine cylinders. The working volume that 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. It is generally expressed in liters (L). Cylinder Volume: Because a larger cylinder volume (displacement) can accommodate more combustible mixture (air-fuel), under the condition that all other factors are the same, an engine with a larger cylinder volume (displacement) will definitely have more power.
