What is the difference between t and l in car displacement?

[BrielleRose]

Difference between t and l in car displacement: 1. Different representations: t stands for turbocharging; l stands for natural aspiration. 2. Different application scopes: t turbocharging is mostly used in private cars; l naturally aspirated engines work more stably with better continuity, making them suitable for racing cars. A turbocharged engine is essentially a naturally aspirated engine equipped with a turbocharger to increase the engine's output power and torque. Although turbocharged engines are more fuel-efficient and produce lower levels of carbon monoxide, hydrocarbons, and particulates in emissions, their lifespan is shorter compared to naturally aspirated engines of the same displacement.
