What does the T in car displacement mean?

[Elliot]

Car displacement T is the abbreviation for turbo, meaning turbocharging. Here is a brief introduction to turbocharging: 1. Function: The turbocharging device can change the air intake of the engine, allowing the fuel to burn more fully in the cylinder, thereby increasing the engine's output power. Turbocharging uses the exhaust gas generated during the operation of the internal combustion engine to drive an air compressor to increase the air intake. 2. Principle: The turbocharger is essentially an air compressor that increases air intake by compressing air. It utilizes the inertial impulse of the exhaust gas from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller compresses the air delivered through the air filter pipe, pressurizing it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and turbine speed also increase synchronously, allowing the impeller to compress more air into the cylinder. The increased air pressure and density enable the combustion of more fuel, and correspondingly increasing the fuel amount can enhance the engine's output power.
