What does 1.2t in a car represent?

[DiZane]

Car 1.2t indicates that the vehicle is equipped with a 1.2L displacement turbocharged engine. The preceding number represents the engine's displacement, while the 'T' stands for Turbo, meaning turbocharging. This can be understood as the engine utilizing forced induction technology, typically applied to small-displacement engines. Below is relevant information about turbocharged engines: 1. Core Concept: A turbocharged engine relies on a turbocharger to increase the engine's air intake. The turbocharger essentially functions as an air compressor. 2. Working Principle: It utilizes exhaust gases from the engine as power to drive the turbine in the turbine housing (located in the exhaust passage). The turbine then drives the coaxial impeller located in the intake passage, which compresses fresh air delivered through the air filter pipe before sending it into the cylinders. As engine speed increases, the exhaust gas velocity and turbine speed synchronously accelerate, enhancing air compression and consequently increasing the engine's air intake, thereby boosting the engine's output power. 3. Function: The engine delivers higher power and torque. Models equipped with turbocharging typically output approximately 40% more power than non-turbocharged models.
