What does 2.0L mean in cars?

[GenevieveLynn]

The 2.0L in cars stands for 2.0, where L represents naturally aspirated, meaning the engine has standard air intake. Here is relevant information: 1. Naturally Aspirated: Naturally aspirated is a type of car air intake that relies solely on atmospheric pressure to force air into the combustion chamber without any supercharger. Naturally aspirated engines offer far superior smoothness in power output and direct responsiveness compared to supercharged engines. 2. Displacement: Displacement (Swept-volume) is a specialized term in hydraulic transmission, referring to the volume of fluid inhaled or discharged 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 'power performance'.
