What does TSL mean in cars?

[FinnRose]

TSI refers to a turbocharged direct injection engine, which is more advanced than FSI and belongs to the category of high-power, high-torque engines. The relevant introduction of turbocharging is as follows: Characteristics of turbocharging: The characteristic of turbocharging is that after the turbo engages, the engine's air intake efficiency increases, allowing the engine to deliver greater power. Meanwhile, mechanical supercharging can effectively compensate for the delay in turbocharging, as mechanical supercharging can provide a boosting effect to the engine right from idle speed. Comprehensive advantages of TSI engines: They have minimal power loss, relatively increased output power, and can achieve greater torque and horsepower with smaller displacements, thereby delivering enhanced performance.
