What does a 2.0L car engine mean?

[AustinMarie]

Car engine 2.0L means: 2.0 indicates the displacement is 2.0 liters, and L stands for naturally aspirated, which refers to the engine's standard air intake. Naturally aspirated is a type of car air intake system that relies on atmospheric pressure to force air into the combustion chamber without any supercharger. Naturally aspirated engines are far superior to turbocharged engines in terms of smooth power output and direct response. Displacement (Swept volume) is a specialized term in hydraulic transmission, referring to the volume of fluid inhaled or exhausted per stroke or cycle. Generally, a larger displacement means the engine releases more energy (converting chemical energy from fuel into mechanical energy) per unit time, resulting in better performance.
