What does 1.2t engine mean?

[Maverick]

Engine 1.2t refers to the engine displacement of this vehicle being 1.2 liters, where the 't' stands for turbo, meaning turbocharged. The Chinese explanation of turbocharging is as follows: 1. A turbocharged engine is an engine that relies on a turbocharger to increase the intake air volume. The turbocharger (turbo) is essentially an air compressor. It uses the exhaust gases expelled by the engine as power to drive the turbine in the turbine housing (located in the exhaust passage). The turbine, in turn, drives the coaxial impeller located in the intake passage, which compresses fresh air delivered by the air filter pipe and then sends it into the cylinders. When the engine speed increases, the exhaust gas expulsion speed and turbine speed also increase synchronously, thereby enhancing the air compression level. This results in a corresponding increase in the engine's intake air volume, which can boost the engine's output power. 2. The greatest advantage of a turbocharged engine is that it can significantly increase the engine's power and torque without increasing the engine displacement. After installing a turbocharger, an engine's maximum output power can increase by approximately 40% or even more compared to when it is not equipped with a turbocharger.
