What is the difference between L and T?

[HarleyRose]

T stands for turbo, meaning turbocharged. L stands for liter, indicating the engine displacement in liters. Engines marked with L without a T are generally naturally aspirated engines. The main differences between them lie in their nature, working principles, and performance. Below is an introduction to turbocharged engines: 1. Principle: A turbocharger is essentially an air compressor that increases air intake by compressing air. It uses the inertial force of exhaust gases from the engine to drive a turbine in the turbo chamber, which in turn drives a coaxial impeller. The impeller compresses air delivered through the air filter pipeline, pressurizing it before it enters the cylinders. 2. Power: As the engine speed increases, the exhaust gas flow rate and turbine speed also increase synchronously, allowing the impeller to compress more air into the cylinders. The increased pressure and density of the air enable more fuel to be burned. By adjusting the fuel quantity and engine speed accordingly, the engine's output power can be increased.
